Week 8 kicked. my. butt.
The exhaustion hit in a way that made workouts feel optional… and sleep feel non-negotiable. I skipped almost every planned session this week, and that would have spiraled me in my first pregnancy.
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 pregnancy and this one
How I’m approaching movement right now
Starting the process of interviewing birth doulas and finding support that aligns with your values
Practical nutrition strategies for when you’re too tired to function
We’re also talking about real-life fueling when you’re exhausted:
Grocery delivery as a survival tool
Stocking up on foods you can actually tolerate
Giving yourself full permission to lean on takeout and frozen meals
Because this season is about adaptation.
If you’re a pregnant runner navigating fatigue, identity shifts, and changing expectations, this one will feel like a deep exhale.

Week 7 is officially here… and I feel pregnant now.
In this episode, I’m sharing what’s shifted physically, emotionally, and in my training this week. From nausea and food aversions to sore boobs while breastfeeding my 14-month-old, things are definitely changing.
We’re talking about:
Why breastfeeding has suddenly become uncomfortable
The nerve-y hip sensations + abdominal pressure
Snacking constantly to manage nausea
Body image this pregnancy vs. last time
Why I decided to stop working with my running coach
How running and lifting are still feeling (surprisingly!) good
The fatigue that’s creeping in
There’s something powerful about recognizing when your body needs a shift and trusting yourself enough to make it.
If you’re navigating pregnancy as an athlete, this one will feel like sitting on the couch with a friend who also packed snacks.

Week 6 of pregnancy was a LOT.
I ran a half marathon, started proactively snacking on carbs to keep nausea at bay, and officially entered the era of peeing nonstop and feeling… kind of icky in my belly.
In this episode, I’m sharing what running felt like this week, why I’m committing to fueling during runs (even the short ones!) for the rest of pregnancy, and how early pregnancy hormones can mess with your mood before food aversions even show up.
We’re talking:
Why carbs are clutch for nausea prevention in early pregnancy
What abdominal pressure and that “off” belly feeling can mean (and when it’s normal)
Emotional swings, anger, and the mental side of early pregnancy training
How I’m thinking about fueling differently as a pregnant runner
This is not medical advice. It’s one runner, one body, one very real week of pregnancy. If you’re running pregnant, thinking about it, or just want to feel less alone in the weirdness… you’re in the right place.

Welcome to episode one (Week 5 of pregnancy!) of The Pregnant Mother Runner Diaries and plot twist… I’m pregnant.
In this episode I’m sharing the very real, very fresh feelings of finding out. And, yes, I took approximately 47 pregnancy tests 😂…Obviously.
We talk about:
Exercising safely in early pregnancy and what the research actually says
The weird tingliness in my low back and hips
Headaches and thirst and “is this pregnancy or just life?”
Not showing at all and not really having symptoms yet
The complicated mix of excitement about a baby and disappointment about potentially losing fitness
Training still feeling strong
Nursing my 13 month old while newly pregnant
We’ll cover what current guidelines say about exercise during uncomplicated pregnancies and how I’m approaching training with curiosity instead of fear.
As always, this is my personal experience as a runner and registered dietitian. It is not medical advice.
And if you want deeper dives into fueling, body image, and metabolism for runners, come hang out with me on Dear Runner Bod.
