Running Preggers: Baby Belly Support

A maternity belt is going to be a must have for most running moms-to-be as they near the third trimester. Many women even with the support of a maternity belt decide to stop running during the third trimester because it becomes too uncomfortable. There is no shame in taking a brake during your last weeks of pregnancy ladies.

Keep in mind a belly band and a maternity belt are different. If you’re running, a belly band isn’t going to help support your baby belly. The band allows you to continue to wear your pre pregnancy clothing for a longer time and delays the purchase of maternity clothing. It will cover your belly as your shirt creeps up and it will hold your pants up when you leave them unbuttoned and the zipper more and more down as baby grows.

A maternity belt will help lift some of the baby belly weight up and distribute it more evenly across your back and hips. You can start wearing one whenever you want. I started wearing mine around week 27. I actually tried a bit before then, but found that my belly wasn’t big enough to make any difference. I should have bought a size small rather than a medium, which would have allowed me to wear it sooner.

When you reach the third trimester, baby is about 2 pounds, still pretty small, but over the next 13 weeks baby will add on 4.5-5 pounds, and maybe a little more. Running with a medicine ball attached to your abs that increases in weight every week is tough. Many women begin to feel very tired and have round ligament pain as the uterus grows to its max height and baby’s weight increases. Pelvic pain can be problematic because the hormone relaxin is relaxing those tendons/ligaments holding your pelvis together. You can also have a feeling of increasing downward pressure (not time to exit yet kiddo), which is uncomfortable.

I bought the Gabrialla belt after reading some reviews from other running mamas. Things you want to be aware of when selecting your belt are: first, washability. That thing is going to get sweaty and you’ll want to wash it pretty regularly. Second, regular washing, means you want it to be durable. The third thing to consider is breathability. Being pregnant generates a lot of extra heat, so wearing something around your middle that traps heat in, is not going to work.

The Gabrialla goes around your low back and then under your belly. If you do it up too tight it can push on your bladder. You want it snug and comfortable. My daughter will kick and push at the belt before and after our run, but she is rocked to sleep while we are running. You can wear it over or under your clothing. I wore it over just because I didn’t want to risk any chafing.

I’ve had a few women come and ask me about the maternity  belt when I finish a workout at the gym and I’m always happy to help keep another mom-to-be active and happy.

 

Running Preggers: Clothing issues

Sure, you can just wear larger sizes of clothes, but who really wants to do that? It’s much more fun to show off that baby bump, especially, at the gym, on the trail, or out running on the road. Show the world pregnant women are strong and fit.

The problem is maternity fitnesswear is kinda expensive and then you’re only going to be wearing it for a few months. Every woman and every pregnancy is different and will change what clothes you need and when you need them. If you’re planning on future pregnancies and/or you have extra money (after all the baby purchases), buy the clothes that make you the most comfortable, even if they are a little pricey.

Depending on how you’re carrying your baby (high or low) changes what you may need. If your carrying low, pants and shorts can become a problem before shirts do. If you carry high, shirts are a problem earlier in your pregnancy. By the end, it’s all going to be a problem though. Shorts with drawstrings and longer shirts may be the most cost-effective solution.

Sports bras are another ball game all together. You’re going to need a larger size and you may need to go up a size after that depending on how things play out. If you’re planning to breastfeed your baby, you’ll want to invest in some nursing sports bras, plus their just a bit more comfortable than normal nursing bras.

Sports bras are expensive especially as the size increases and you need more and more support. No one wants the girls bouncing around and when you’re pregnant it can be painful. If you’re going to be breastfeeding, it is probably worth the extra cost to get the higher quality nursing bras that have good support since you’ll be using them for a while. But, don’t get them too early because once your milk comes in you could go up another size. You’ll want to wait about five days postpartum before you get more than one (because you might want one to wear home after the birth).

What’s a woman to do, when you know your bra size is most likely going to change throughout pregnancy and the sports bras are pricey? Double up. Yep, wear two bras. It does create more heat, which can result in a slight heat rash for some women. But I can get two cheaper bras for less than a really high quality supportive one. If the girls were going to stay that size forever, I’d buy the more expensive one, but they’re not.

Another clothing issue you may be lucky enough to experience is chafing. Your higher body temperature and blood volume make you start sweating earlier in your workouts. Add that to your not so great fitting clothing and you’ll be investing in Body Glide or other anti-chafing cream.

Good luck ladies!

Running miles: I’ve been able to maintain the 3 miles a day at a 10:30 pace. I’m 31 weeks three days pregnant. I’m supplementing with the elliptical or stair master for the rest of my aerobic workout.

Running Preggers: Relaxin

I wish I were trying to be cute and leaving the “G” off Relaxing, but Relaxin is a hormone produced in increasing amounts during pregnancy. It’s a necessary hormone, but as an athlete, it’s not something you want in increased amounts. Relaxin is a protein-based hormone found in men and non-pregnant women. Pregnant women have ten times the amount as non-pregnant women.

Relaxin relaxes the blood vessels, ligaments, and tendons in your body. It begins its work in the beginning of pregnancy (before actually) by preventing contractions in the uterine wall and making implantation easier. It allows your blood vessels and arteries to expand to accommodate the extra blood volume. As you’re baby grows and shoves your internal organs into your ribcage you’ll be glad relaxin has made expansion of your abdominal muscles and ribcage possible. What you’ll be most happy about is relaxin ensures that your pelvis will be able to expand not only to accommodate your growing child, but to allow the child to be born.

Relaxed tendons are a problem if you are an athlete. It can be problematic if you’re not an athlete and you just want to go about your day without any pain or discomfort in your joints. Instability in your ankles, hips, and knees is something runners try to minimize and correct through strength training. When you’re pregnant, strength training isn’t going to help and you really, on some level, don’t want it to help because that baby has to exit somehow.

The instability can cause achiness and pain in your joints with just everyday activities, let alone running. Relaxed tendons and ligaments places you at higher risk of injury, even when doing exercises you have been doing for years pre-pregnancy.

What all of this means for pregnant runners is be careful and rethink increasing your miles or the intensity of your running workouts during your pregnancy, especially, during the first and third trimester when relaxin levels are at their highest. You’re also likely to feel increased soreness after runs, especially, in your pelvic girdle, hips, and lower back. Try using a maternity belt to help reduce the pressure of the baby on your pelvic joints.

You’ll likely have to decrease your miles and your pace as your son or daughter grow and their debut approaches. Reducing your miles to prevent injury, especially, an injury that could stop you from getting back to running after baby is born, is a small price to pay. Cross training with low impact exercises, such as swimming and cycling, will become your go to activities at the gym. I know this can be frustrating, but keep in mind it also means you’re closer to holding your little one in your arms.

Running Preggers: Shoes

Since the past few posts have been about shoes, I thought I should just continue the theme and just complicate the whole issue with being pregnant. There are obvious changes to a woman’s body that occur when she is pregnant that will impact what she wants and should put on her feet.

There are many articles out which stress how important it is for women who are pregnant to wear clothes and shoes that are comfortable. This is even more important if you are a runner. The recommended weight gain for a woman, with a healthy weight to start with, is 25 to 30 lbs during pregnancy. I’m not going to get into the details of where all that weight comes from, but it’s certainly not all fat (only about 7-8 lbs actually).

The weight alone is reason for you to consider your shoes. If you’re running in a shoe with minimal cushion you may want to consider running in something in the mid range. Going high cushion, if you’re not use to them, is not recommended because it can cause some instability in the ankles, knees and hips.

Pregnant runners do not want to do anything to add to the instability of their body since pregnancy hormones and an ever increasing belly does that enough. The hormone Relaxin causes our tendons and ligaments to relax in preparation for child birth. This begins to happen fairly early in pregnancy and continues until the very end.

No tendon or ligament is left behind. From head to toe your ligaments and tendons relax. This can cause instability in your hips, knees, and ankles. You’re larger belly also throws off your balance and stability. If you start to have some aches in your joints consider switching to a more supportive shoe or adding insoles, if you don’t have them already.

The hormone Relaxin also makes your feet flatten out more. The repeated flattening of your feet causes the tendons and ligaments to stretch out, possibly permanently. The translation, bigger shoes. You’re likely to go up a half size during pregnancy and may stay that way. You could also need wider shoes. Many women experience swelling in their feet and ankles too. When you do end up at the running store, and you will if you’re planning to run throughout your pregnancy, make sure you try on shoes with more support, more length and more width. Don’t just go for your tried and true shoes.

It can be hard to let go of your sleek running shoes and move into a clunky stability shoe that weights nearly double your racing flats, but preventing injury and running safe through your pregnancy is what’s important. You’ll have your favorites (just in a larger size) cradling your feet soon.

Weekly miles: With baby girl growing more now (25 weeks along), running longer has become more uncomfortable, so over the past two weeks I’ve switched from 3 two hour runs to running one hour a day.

What’s in a Shoe? Cushion.

Cushioning is another place where you’re going to see or hear the word minimalist. I’m going to stick with high cushion and low cushioned shoes as terms to avoid confusion.  Cushioning is usually talked about in millimeters (mm). As we have seen in recent years, there are shoes out there with barely anything under your feet, aka barefoot running shoes, and those with cushioning over an inch thick (an inch is 25.4 mm).

The theories on why one shoe is better for runners abound and often contradict one another. The idea behind high cushion is that it reduces impact forces and thus reduces injury. What does the research say? Research does not support a lower injury risk or less muscle fatigue with a higher cushioned shoe. It is the alignment of our lower leg that changes impact forces, and the alignment of our leg is changed due to sensory input our brain receives as we run.

Don’t fret all is not lost my high cushion loving runners. Here are some things we know about running with and without cushion.

Heel striking runners should not run in low cushioned shoes. It can be hard to tell if you are a heel, midfoot, or forefoot striker. The most reliable way is to look at the bottom of your shoe or have someone watch you run (when you’re not paying attention to your foot strike, because you’ll alter it). If you have more wear on the heel of your shoe, you’re a heel striker. About 80% of runners are, it’s not a bad thing, so long as you wear the right shoes. If the wear on the sole of your shoe is on the forefoot, you’re a forefoot striker. This is pretty rare and is usually sprinters and shorter distance runners.

Higher cushioned shoes can cause instability in the ankles and hips, especially, for beginning runners who have not developed the ankle and core strength to tolerate the instability. This instability can also be a problem on trails, which are already uneven. Some high cushioned shoes compensate by having a wider sole, although, this solves SOME of the instability it adds the problem of a wide ass shoe. A wider sole can get stuck between rocks easier. Also keep in mind that a wide ass shoe sole does not always translate into a wider toe box.

High cushioned shoes can protect the bottom of your feet from rocks, roots, and other nasties. As we age we lose some of the natural cushioning on the bottom of our feet making a higher cushioned shoe possibly a better option for runners as they age.

Heavier runners (over 170 for men and over 160 for women) are going to want a shoe with stiffer cushioning rather than the pillow soft stuff because of the compression that occurs when you land. If you have super soft cushion, it’s not providing you with much protection.

What I want you to take away from this whole series on shoes is everyone is an individual and research results are an average. Sometimes if researchers look at individual runners there is a difference. It could just be the runner’s belief (placebo effect) or other biomechanical differences between runners, but if it makes a difference for you, stick with the shoes or dump them as appropriate.

Wear what makes you happy and don’t be afraid to dry new stuff.

Happy running.

What’s in a Shoe? Heel to Toe Drop.

Why do we care about heel to toe drop? Well, because it’s one of the aspects of a shoe that have people thinking it could help or contribute to injuries.

The heel to toe drop of a shoe is the difference of the sole’s thickness at the heel compared to at the toe of the shoe. Most shoes have a heel to toe drop of 10-12 mm, while minimalist shoes have a heel to toe drop of less than 4 mm. To give you an idea, an inch is 25.4 mm

For clarity’s sake, I want to be clear on what I mean by minimalist in this post. There are two major tenets of minimalist: first, the amount of heel to toe drop and second, the amount of cushioning. This post is talking about heel to toe drop, which I’ll use instead of the term minimalist. If amount of cushioning comes into play in this post, it will be clearly indicated.  If anyone is interested the other tenets are weight, added motion control technology and flexibility. Here is a scientific article on how a minimalist shoe is defined.

The most recent research says there’s no difference in injury rate in runners who run in a lower drop shoe as compared to those who have a higher drop shoe so long as the runners who have switched to lower or zero drop have done so with an adequate transition, which we’ll talk about in a second.

A lower heel to toe drop could be good for people with a neuroma or arthritic changes in the big toe joint because it places less pressure on the forefoot. However, they may not be good for people with plantar fasciitis or Achilles/posterior tibial tendonitis because a lower heel to toe drop requires more extension in your Achilles, knees and hips.

Transition to a lower or zero drop shoe is critical, and it can take weeks, so before you buy your zero drop shoes, make sure you’re committed to the transition. You should start by wearing your zero drop shoes for a 1-2 miles of your runs and then increase a little each week. If you start to feel soreness in your lower leg or knee, don’t increase the distance at all and think about backing off a little. This is true whether your new to running or a more experienced runner because most people walk around in shoes with a 10-15 mm heel to toe drop.

Research on body weight compared injury rate in runners in the Asics Piranha, 9mm to 4.5 heel to toe drop, and Asics Gel Cumulus, 23 mm to 13 mm heel to toe drop.  The runners who were selected to run in the Pirahna’s did a 26-week transition to the shoes. The results showed runners over 165 lbs (the average for the study group) had an injury rate four times higher than those under 165 lbs. The researchers also looked at the type of weight, so was the higher body weight due to muscle mass or height as compared to someone who is overweight due to the amount of fat they are carrying on their body. The results showed no difference, which lead to the conclusion that it is the weight regardless of where it comes from that is correlated with the higher injury rate.

What does lower injury risk when it comes to heel to toe drop? Running in shoes with different heel to toe drops. This makes your musculoskeletal system adapt and become stronger under different circumstances.

Happy running. Next up is amount of cushion.

 

What’s in a Shoe? Stability.

Everyone’s Feet pronate. Pronation is when your foot rolls inward to distribute the forces of impact as your foot makes contact with the ground. Normally, this is about 15%. The arch of your foot is the biggest factor in your pronation.

There are three basic types of shoes as far as stability goes. A neutral shoe, which allows your foot to move in its natural way; a stability shoe, which gives your foot some assistance to not over pronate; and a motion control shoe, which gives your foot maximal support to not over pronate.

If you go into a running store to purchase your shoes, they are likely to watch you run and walk in bare feet and then with various shoes on. They are trying to determine if you pronate, supinate beyond what’s normal. Their recommendations for shoes typically follow this pattern:

People with normal arches will typically run in either a neutral or stability shoe.

Those with low arches or flat feet typically use a stability or motion control shoe. Flat footed runners typically overpronate meaning their foot rolls in farther than it should toward the big toe. Because of this, a stability shoe is usually a good option. However, if you see that the outside of your shoe’s sole is being worn faster than the rest, you’ve got too much control going on in the shoe and need to switch to something neutral.

Heavier runners (men between 160-180 and women 140-160) who over pronate will likely need more than just the average stability shoe. Look into the motion control shoes to help with the overpronation.

Those with high arches under-pronate (supinate) and so typically do best in a neutral shoe. A little note here: Women have a greater quadricep angle and wear down the outside of their shoes more quickly than men, but it doesn’t mean you supinate.

Over or under pronation can place you at high risk for particular types of injuries. Overpronation causes extra stress and tightness in the muscles. Too much motion in your foot can cause calluses, bunions, runner’s knee, plantar fasciitis, and Achilles tendinitis.

Under pronation (supination) places extra stress on the foot, which could lead to you developing ITband syndrome, Achilles tendinitis, and plantar faciitis.

The problem with all of this information is the research doesn’t really support it. It’s all theory. Now, I’m not saying you should throw out your tried and true running shoes and go with something different as far as stability. What the research supports is choosing the amount of stability that you are most comfortable in. This may take some trial and error. You can pull on a pair of shoes and they feel great in the store, but when you take them for a run, they just don’t work. This is why you should always check the return policy of a store before you buy the shoes.

Pronation can change as you become a more experienced runner because the muscles and tendons of your feet and ankles become stronger. When I first began running, I overpronated, then I supinated for a while. When you go to get new shoes, try some different things on. You may find your feet have changed and you’re more comfortable in a different shoe.

The stability of a shoe won’t necessarily impact your ability to run faster either. The issue will be the weight of the shoe. Heavier shoes are going to slow you down. For every 100 g  of shoe weight you can anticipate a 0.8% decrease in speed. The more stability you have in a shoe, the heavier it’s going to be.

The big take away from all this is, the stability of a shoe isn’t going to reduce your injury risk. Go with what is comfortable, but check in every once in a while to make sure your favorite shoe, is still your favorite.

Happy running. Next up is heel to toe drop.

Running Preggers: When you have to go, go!

Running can have some interesting challenges relating to using the bathroom. If you’re a trail runner, this isn’t so much of a problem, although you should be burying or packing out solid waste. In the woods, you can just duck behind a tree. Looking up and down trail before, of course. As a road runner, depending on the time of day when you run, bathroom access is also pretty simple.

When you’re running for two, it’s not that simple. Why would it be? Every bodily system you can think of is altered when you’re pregnant (although I haven’t heard anything about your perception of sound…). It’s very important that you don’t wait to go to the bathroom, number one or number two.

Holding your urine is not just uncomfortable when you’re running, but it can cause infections, even in non-pregnant people. The real problem is the frequency of needing to go pee. Even in early pregnancy, when the baby is smaller than a pea, women will need to go more often. This is because your body increases the amount of blood it pumps and your blood volume, so you’re drinking more water and your kidneys and bladder are working overtime.

Blood volume increases until the third trimester and making sure you’re hydrated throughout the day will continue this pattern of needing to go all the time. And then there’s the baby. As baby grows he/she puts pressure on your bladder making you feel like you have to go even when you don’t have that much in there.

You can be running along enjoying the beautiful day and then bam, you have to go right now. You think, “but I went 15 minutes ago!” doesn’t matter, you have two choices: stop to pee again, or pee your pants. This can make running frustrating at times because jumping into the bushes to pee in a neighborhood is frowned upon. Getting off the treadmill all the time is also frustrating. So, for the potty problems, trails are your best option, in my opinion.

As for number twos, unfortunately, pregnant women don’t have to worry too much about those while they’re running. In fact, most pregnant women wish they had to worry about that when running. Constipation is another lovely side effect of being pregnant. The hormones in our body slows digestion down to a crawl, so the baby can suck as much nutrients out of the food we eat as possible. And then there’s the baby. As baby grows he/she compresses your intestines and shoves most of your organs up into your ribcage further complicating your ability to digest food and move it through your body. All in the name of love.

A maternity belt can help alleviate some of the pressure on your bladder and hopefully you won’t have to go pee, so much. Don’t restrict your water intake to prevent the frequent bathroom stops as tempting as that may be. You could wear very absorbent panties, but they would likely chafe something awful.

Weekly miles: 30 miles this week!

Running Preggers: Healthy Mama; Healthy Baby

The default recommendation for pregnant women is to exercise while pregnant, at least three days a week for 30 minutes. Basically, the same recommendation for everyone. There are many benefits to mom if she begins exercising and if she continues exercising while pregnant. Yes, the experts agree it if you haven’t been exercising starting during pregnancy is just fine. You do need to listen to your body and if you have a high-risk pregnancy make sure and check in with your doctor before you start anything.
Many of the benefits are what you would expect because they are the same benefits for everyone: better sleep, better mood, cardiovascular health, decreased levels of stress, weight control, respiratory health, and on.
Mom’s to be also improve their circulation, which helps to prevent constipation (big win). Preventing constipation, of course, reduces your chances of getting hemorrhoids. It also helps with swelling in ankles, varicose veins and leg cramps (ah the joys of pregnancy). Doing some core strengthening can reduce and prevent back pain as well.
But another big benefit for mom’s who exercise throughout their pregnancy is a shorter labor and less likely to have a perineum tear, if you do tear it’s not as bad. Unfortunately, it’s not going to reduce the pain you may experience.
Alright so exercise is good for mama, but that’s not enough to get you off the couch when you are tired, don’t feel good, and moody. Well we can through in a healthy dose of parental guilt then.
An exercise physiologist and anatomist at Kansas City University of Medicine and Biosciences, Linda May, conducted a study with 66 moms to be and their fetuses. She measured fetal heart rates at 28, 32, and 36 weeks of pregnancy after splitting the women into two groups: those who exercised at least 3 days a week for 30 minutes and those who didn’t.
Linda May was measuring the babies’ heartrate and the heart rate variability. Variability is the span between beats. Increased heart rate variability means a healthier heart and better overall health because the heart functions more efficiently.
In babies whose moms were exercising, Linda May found by 32 weeks there were differences between the two groups and by 36 weeks there was a “big, significant change”—lower heart rate and increased heart rate variability. The moms who exercised more had babies with lower fetal heart rate and increased heart rate variability.
Those benefits to baby didn’t stop after the baby was born either. The benefits continued to be seen when the babies were brought back in at one month of age. So if you can’t do it for yourself, do it for your growing baby.

Weekly Miles: I’m back running from the knee issue this week and started with 18 miles. I’ve found consistent rolling of  my shins is dong the trick, which I don’t normally roll. I plan on running outside more next week. I also picked up a maternity support belt to take some of the pressure of the baby off my bladder.

Running Preggers: Trail, road, or treadmill?

Sometimes we don’t have much of a choice about where to run, but some of us are lucky and have many options. Over the last few years, close to 100% of my running has been on trails. It has been amazing, but now I have to adjust back to being more flexible about where I run. I hate having to run anywhere other than in the mountains. I really do. But in reality, I know that there are actually few runners who are able to run exclusively on the trails.

Running while pregnant makes you take a lot more into consideration when you are choosing your running routes. Safety and listening to your body become even more important when you’re pregnant. I’m not saying we runners throw caution to the wind when we’re not pregnant, but when it’s just you, you’re more willing to deal with uncomfortable conditions and slightly higher risks.

During the first trimester, and longer for some women, you must contend with being tired and not feeling well (morning sickness). Both of these can put a huge damper on running, especially, if you have the option of sleeping in later and just running on the treadmill or road instead of driving to the mountains.

Throwing up while running is not something unusual in the ultrarunning world, but it’s also not something we want to deal with during every run either. Choosing a short loop route closer to home or a treadmill when morning sickness is lurking around every corner is more appealing. Then if something goes wrong, you have the option of stopping right away and getting home or at least somewhere more comfortable quickly.

The trails are ideal for the increased urination problem, at least for those who have no qualms about peeing in the woods. Roads make it difficult because you have to plan routes with bathrooms at regular intervals. However, that may not solve the problem. In my experience, there is no predictability to when you will need to go. Sometimes it’s every thirty minutes; sometimes it’s every ten. I can’t seem to make it longer than 45 minutes when running. What’s worse is you may not realize you need to go until you bounce just right and then you have to go RIGHT NOW.

Falling is something you want to think about too. When I wasn’t pregnant, I didn’t like falling, but the chance of falling never stopped me from bombing down the side of a mountain. Now, I think a lot more about the risk of falling a route poses. Early in pregnancy falling is really unlikely to harm the baby. Even into the second trimester, baby has a lot of room to move and is protected by muscles and amniotic fluid. As baby gets bigger, they don’t have anywhere to go to get out of the way of an impact making the risk of falling increase throughout pregnancy. The shift in your center of gravity adds to the likelihood of falling too. As does the instability of your joints because of the hormone relaxin (more on this in another post).

Weather is another thing that plays a bigger roll in deciding on a running route when you’re pregnant. I’ve always said there’s no bad weather, only bad gear, but when you’re pregnant, that’s different. Extreme high and low temperatures have a bigger impact on you when you’re pregnant and ice. Rain shouldn’t be too problematic as long as you stay warm. Ice and snow are another problem entirely (see previous paragraph).

As far as calories go, they get used up quicker the further along you are in your pregnancy. In the first trimester you shouldn’t need to adjust calorie intake. Starting with the second and then throughout the third (and if breastfeeding) you’re going to need more calories, 300-500 extra per day. This could mean taking something small on shorter runs. A two-hour run was no problem without calories for me, now that I’m just past twenty weeks pregnant I’m starting to feel the drag in the last 30 minutes.

Air quality is the one thing runners, along with everyone else, pregnant or not, should take into consideration when deciding where to run. You need your lungs and heart. Running when pollution is thick in the air will increase your risks for health problems in the present and in the future. One thing that the ULTRA research study has uncovered is a higher rate of allergies and exercise induced asthma in endurance runners and one of the hypothesizes is because we’re out in the pollution more than the average person, we develop these types of problems more than others.  When you’re breathing for two, it’s even more important for you bite the bullet and run indoors on a track or treadmill.

I hope you all had a Merry Christmas and will have a Happy New Years!

My running update: I’ve developed a bit of pain in my left knee, which I think is begin caused by all the treadmill running and lack of foam rolling. I’ve backed off my miles this week, but plan to bump them back to the 36 miles as soon as my knee is feeling better.
