Are you letting your watch boss you around? 😏

In this episode of Dirt Nap Diaries, I’m breaking down why RPE (Rate of Perceived Exertion) beats heart rate training for trail runners every single time. Numbers can be useful, but they don’t always tell the truth—especially in the heat, on climbs, or when life stress shows up.

I’ll share stories from my own athletes who’ve been trapped by their HR zones (and the ones who try to go hard every run), why your watch is lying to you, and how learning to run by effort will make you stronger, more confident, and ready for the unpredictable parts of the trail.

What you’ll hear in this episode:

  • Why heart rate data can be misleading (lag, drift, stress, terrain).
  • How RPE gives you instant, terrain-proof feedback.
  • What each RPE range really does for your training.
  • How to stop obsessing over numbers and start trusting your body.
  • A weekly challenge to log your runs by effort, not HR.
