Dear Runner Bod,

When Life Gives you Lemons on Race Day

Sometimes race day doesn’t go the way you trained for. In this episode, I open up about my September half marathon — the disappointment I felt crossing that finish line, the messy middle of processing it, and the mindset shift that’s helping me move forward. If you’ve ever walked away from a race wondering “what was all that work for?” — this one’s for you. Let’s talk about how to turn the sting of a tough race into fuel for your next start line.

The Dark Side of ‘Calories In, Calories Out’ for Women Who Run

You’ve been told that “calories in, calories out” is the holy grail , but for female runners, that formula can quietly tank your metabolism, mess with your thyroid, deplete your iron, and weaken your bones.
In this episode, Serena breaks down the science of why low-energy availability wrecks hormone balance, how chronic dieting blunts your metabolism, and what to do instead if you actually want to perform.
