Pregnancy Week 23: The Fear of Resting and Running Out of Time 07.07.2026

This week, I will finally get my MRI after taking a complete break from running and lifting. While I wait for answers, I’m walking and slowing down. I also had an emotional pelvic-floor moment when I peed myself after sneezing while holding something heavy. It had never happened before, and it immediately made me worry about what it meant for my pelvic floor and my future as a runner. The nausea i...

Week 21 & 22: Resting, Comparing, and Trying to Trust My Body 30.06.2026

In this week’s pregnancy update, I’m combining weeks 21 and 22 and sharing what it has been like to navigate ongoing lower back and butt pain while pregnant. After dealing with this pain for about a year and seeing different PTs, I finally booked an appointment with sports medicine, where they brought up the possibility of a sacral stress fracture. Now I’m waiting to get an MRI approved so we can...

Week 20: Bumpin’, Slowing Down, and Dressing the Body I’m In 23.06.2026

At 20 weeks pregnant, the bump is officially bumpin’ and I’m fully living in pregnancy clothes now.

I also talk about how training is going right now: running still feels good, but I am definitely slower. And eve...

Week 19: The Belly Popped, the Pace Dropped & the Sugar Cravings Entered the Chat 16.06.2026

This week, the belly officially popped and I am feeling very pregnant in the cutest way. Running and workouts are still feeling good and comfortable, but I am definitely slowing down, which is a very normal part of training through pregnancy. I’m also talking about sugar cravings this week, not from nausea or food aversions this time, but from that very real “I could eat dessert for every meal” ki...

Grief, Hospice, & Pregnancy: Weeks 16–18 09.06.2026

 In this combined pregnancy update for weeks 16–18, I’m sharing a much heavier season of life. My dad was placed on hospice and passed away during these weeks, and navigating grief while pregnant felt surreal and overwhelming. I talk honestly about what it looked like to simply survive during this time, letting exercise go for a while, and how emotional stress can change your relationship with mov...

Week 15 Pregnancy Update: Feeling Baby Kicks! 02.06.2026

This week officially felt like a turning point. I’m just loving how amazing it feels AMAZING to enjoy food again and actually feel hungry. I share what’s been different physically this week, including why I think I may have started feeling baby kicks for the first time. I also open up about something heavier going on behind the scenes. My dad has been sick, and balancing pregnancy, motherhood, wor...

It’s giving first trimester energy 😅 In this episode, I’m sharing the real behind-the-scenes of this week: navigating more reflux (earlier than last pregnancy), waves of nausea and food aversions that finally eased up, and that craving for the elusive “second trimester bliss.” On the bright side, I ran a half marathon this week (!!) an...

Pregnant Athlete Problems: When You Feel Strong and Terrible 05.05.2026

Week 9 felt… different. In a good way. After getting absolutely humbled by Week 8 exhaustion, I’m finally feeling a little more like myself. The nausea has backed off, the bone-deep fatigue isn’t as intense, and I was able to get in a long run without feeling completely wiped out after. Huge win. In this episode I’m sharing: What shifted physically from Week 8 to Week 9 How my runs and strength wo...

Pregnancy Week 8: Exhausted, Humbled & Actually Listening to My Body 21.04.2026

Week 8 kicked. my. butt. The exhaustion hit in a way that made workouts feel optional… and sleep feel non-negotiable.

In this episode, I’m sharing: What this level of first-trimester fatigue actually feels like Why honoring your body > forcing fitness The mindset shift between my first pregn...

I Ran a Half Marathon… IN FIRST TRI 21.04.2026

Week 6 of pregnancy was a LOT.
