I have been meaning to write about running during pregnancy for a very long time, yet here I am – finally posting this at nearly 38 weeks pregnant!
Clearly a lot has happened since I ran the Big Sur Marathon last year. That was always the plan – run one last big race, and then attempt another far more challenging endurance event…PREGNANCY! We were fortunate enough to conceive right away, so I cruised from post-marathon recovery right into training for motherhood. We found out the good news shortly after an incredible trip to Hawaii, where we ran almost daily on the beach and had an epic trail running adventure down and around the Haleakala crater. I didn’t realize that I was 3 weeks pregnant at the time (if that even counts) and thoroughly enjoyed our 12 miles of running at altitude, hurling ourselves down the crater and across some of the most stunning and dramatic landscapes I have ever seen. It was my last blissfully ignorant running hurrah – before any of the now familiar pregnant running thoughts and concerns entered my mind. E captured the day quite well in his blog and I highly recommend hiking or running there if you find yourself in Maui – check it out!
Once I processed the initial shock and joy of discovering I was pregnant, one of my first thoughts was, “Wait – what about my running?!?!” I was averaging 30-40 miles per week pre-pregnancy, not training for anything in particular but trying to maintain my fitness after Big Sur for myself, and in case I wanted to squeeze in one last marathon or ultra over the summer. I couldn’t imagine not running. It is such an integral of my life – my “me time,” my release, a way I bond with my husband, and a large part of how I stay fit and healthy. I wanted to keep running as long as I could!
As a running coach, I knew the basics surrounding exercise during pregnancy, including:
- Don’t start any new physical activities – unless it is something relatively gentle (i.e. if you weren’t active before, starting a walking routine is fine)
- Limit or avoid sports that have a higher risk of injury/falling
- Listen to your body and err on the side of caution if something doesn’t feel right – it’s just not worth the risk
- Ensure adequate hydration/nutrition before, during and after exercise to maximize energy levels and recovery
- Avoid exercising in heat or other potentially dangerous weather conditions (e.g. ice)
- Most importantly, follow the advice that your doctor provides you that is specific to YOUR unique pregnancy!
Exercise, generally speaking, is without a doubt beneficial to mom and baby, assuming a healthy pregnancy. There is a great deal of research to support this, leading doctors to encourage most women to perform some type of physical activity for at least 30 minutes each day. But I was already very active – 30 min of walking doesn’t exactly cut it for me – and I couldn’t help but feel nervous, especially during the first trimester, so I wasn’t quite sure how to proceed. I knew that many women ran during pregnancy – some even finished marathons in their second and third trimesters – but there seemed to be conflicting information and opinions out there regarding distance and/or high intensity exercise. Could I continue with my previous mileage? What about long runs? What was safe for me and my baby? There wasn’t a whole lot of concrete information available on the topic.
I found myself doing a lot of googling and and blog reading about other women’s experiences. This of course did not substitute my need for individualized medical advice, and it’s important to note that every pregnancy is different, but it was reassuring and motivating to know that other runners were able to have healthy, successful pregnancies and stay in great shape without sacrificing their love of the sport. Did their running change and was it challenging at times to keep running? Of course! Was it worth it? Hell yeah! Did their successs mean that I would be able to run throughout my entire pregnancy? Definitely not. But I hoped I could and I am grateful my little one allowed me to run as long as I did, up until 36.5 weeks!
It also helped that I have a great OB who has been supportive of my running from day 1. With the thumbs up from her, I kept doing what I was doing, with some key adjustments that I have outlined below. My running obviously shifted as pregnancy progressed, but I pretty much followed these guidelines throughout, based on my experience as a coach and long-time runner, my own research on pregnant running, and my doctor’s advice specific to my exercise and medical history:
- I approached training for childbirth as I would any important race. Preparing for birth (especially if you are planning for a natural one, as I am), is in many ways similar to training for a race. You have an overarching plan that includes all the physical and mental prep work to cross the finish line successfully, but have to take things day by day and adjust that plan as needed to get to that start line healthy.
- I tried to stay flexible. If I felt particularly tired, queasy, or something didn’t feel right, I shortened my run, slowed down, took walk breaks, cross-trained, or took a rest day. As a side note, I didn’t wear a heart rate monitor – keeping heart rate below a certain level for healthy pregnancies is old school advice – but simply paid attention to how I was feeling and adjusted my efforts accordingly.
- Speed was no longer a priority – especially since pregnancy WILL slow you down eventually (for me, this happened later in my 2nd trimester). I cared more about CONSISTENT running. I still did some high intensity exercise to relieve stress and break up the monotony of easier efforts, but only when I felt strong and up until my third trimester, after which I kept things very low key.
- I paid closer attention to the weather. I’m the type of runner who usually doesn’t get discouraged by a blizzard, downpour, or a hot summer day. That had to change! On extra hot days or if conditions were slippery, I adjusted the time of day that I went running, hit the treadmill, or did some indoor cross-training.
- I was extremely careful about my running nutrition & hydration. I carried water if running for more than 4 miles, especially in warmer weather, and carried electrolytes/calories if running longer than 8 miles. I also made sure to have pre and post run snacks (always on my radar though, as a dietitian!).
- I dedicated more time to strength training and lower impact cross-training, especially once my belly got bigger. Running became less comfortable for me around 34 weeks, at which point I started to run/walk and incorporate more spin classes and what I like to call, “Netflix & Elliptical.”
- I bought a Road ID to wear in case something happened to me while I was running, especially for when I was alone. I also carried a credit card and if straying far from home, my phone (which I usually never carry), in case of emergencies.
- I invested in a few key items of maternity exercise wear to stay comfortable as I got bigger. I was lucky in that I could keep wearing a lot of my normal gear until mid/late second trimester, as I already had some flowy and stretchy long tops, large running jackets, and some looser/stretchy shorts and pants. I did find a few things useful to buy, including a couple maternity tanks, a maternity long sleeve zip top, and a pair of maternity tights – all on sale from Old Navy and Gap. I splurged on my For Two Fitness “Running for Two” tank and long sleeve top, as they were too cute to resist!
- I always ran within my comfort zone – and appreciate that this is different for everyone. For example, a half marathon during my second trimester seemed reasonable to me (I did the Staten Island Half at a slower but strong pace), as did running 12-15 miles with my husband on long slow run days during my 1st and 2nd trimesters, but I did not feel that longer distances were worth the risk. During my late second and early third trimesters, I was quite happy running 8-10M and 6-7M, respectively, as my “long” runs. Additionally, I felt solid running on technical trails up until my third trimester, as long as I ran with E and slowed down or walked particularly tricky sections. Our trail running adventures in Asheville, NC (check out E’s post here) at the start of my second trimester were particularly awesome!
- I tried not to compare myself to other pregnant runners – what my body looked like, how much I was running, or anything else. Every pregnancy is different and the only important thing was to respect my own!
- I always kept the “big picture” in mind – heathy mom and baby! Sure, I still had fitness goals – run/exercise consistently and as long as possible – but the ultimate goal always was to keep my baby safe. I’ll be honest, it was a bummer to miss a workout or cut things short because I wasn’t feeling well or my doctor wanted me to be extra cautious at times, but in pregnancy, it’s just not worth the risk.
I never sought to run a specific number of miles while pregnant, but when I realized that 1,000 was within my reach, it become the perfect goal to keep me motivated, especially whenever my running started to feel aimless. The last 50 miles were especially challenging, as I began to feel my increased weight and changes in my gait – a good chunk of those miles were walking – but I’m proud of myself for getting it done. As my doctor told me, my dedication to exercise helped maintain great blood flow to my baby and will likely lead to an easier labor! It also means that my return to running post-partum will not be *quite* so painful (although I know that it will still be pretty tough…).
My path to full-term pregnancy has not exactly been easy – without going into details, we have had many bumps in the road, and the process has been scary/overwhelming at times – but I am extremely grateful to have felt good for the most part and to have been able to stay so active. For the past week, I have only been walking because that is what feels best, but I walk every day for at least 30 minutes and at a good pace. I’m thinking of it as “tapering” for “race day” – I don’t get that same post-run high, but I still feel great afterwards. The finish line is within sight now and I cannot wait to meet my baby girl!
A quick note on training for natural birth – my husband and I enrolled in a birthing class that teaches the Bradley Method. It has been a huge time commitment (8 x 3hr sessions) but SO worthwhile. We knew very little about the birthing process pre-pregnancy and we feel so empowered and prepared now (as much as you can be, that is). E and I have always worked well as a team, often training side by side, exploring trails together, and pacing each other in marathons and ultras, so I knew that I wanted him to coach me through birth. The parallels between running a long race and birthing a baby naturally are actually quite astounding. I have been practicing various physical and mental exercises (e.g. kegels, squats, pelvic tilts, active labor positions, relaxation and visualization, breathing etc.) to help cope with labor pain, and also practicing E’s coaching techniques to make sure that they resonate with me. Kind of like strength training, structured running targeted at your race distance, mantras, and learning the art of pacing, right? Childbirth is not the same as running an ultra obviously, but having run for 12 hours and navigated the physical and mental highs and lows of that experience certainly gives me confidence that I can get through the many hours of labor and delivery!
If you’re interested in hearing more about my experience of running while pregnant, in addition to my coaching and nutrition advice for pregnant athletes, check out this podcast that I did with Jason Fitzgerald of Strength Running! We had such a great conversation on pregnancy exercise and I would love your feedback.
I’ll close out with a photo diary of my running and other exercise adventures while pregnant – check out the captions to see how far along I was. It’s amazing how much my body has changed, even if I haven’t gained as much weight as I thought I would (and believe me, I have been trying hard to gain more, especially in recent weeks). Then again, I have always been a small person and can’t imagine my belly being much bigger! It will be a long road to get my body and my fitness back post-birth, but I know I’ll get there eventually.
