Your Fueling Guide for a Sensitive Stomach

You're on the list

Here is your guide. Save it to your phone before race week.

Seven pages from Rafal Nazarewicz, PhD, founder of Spring Energy: why your gut quits before your legs do, how much to actually eat per hour, two worked fueling plans (a 4 to 5 hour marathon and a 6 to 8 hour 50K), a six-week gut-training progression, and a race-day checklist.
