In Episode 72, I dive deep into the pros and cons of caffeine for runners, sharing both personal experiences and evidence-based insights. From race-day gels and GI distress to coffee habits and sleep disruption, this episode helps you explore whether caffeine is actually helping, or quietly hurting, your running goals.

You’ll learn:
