In episode 32 of the Kinda Fast Podcast, Claire and Travis break down heart rate variability (HRV)...what it actually measures, why runners see it on their watches all the time, and how to use it without spiraling or overthinking your training.

They also hit the latest running news, including Sydney McLaughlin-Levrone’s pregnancy and what it means for women’s track in 2026, plus an inspiring story of a 60-year-old runner who just broke an indoor world record.

Then, they answer a real listener question about surviving treadmill training during brutal winter weather (including how to use incline wisely), before wrapping up with a deep dive into running and mental health...six science-backed reasons running supports mood, stress, sleep, resilience, and mindfulness.
