Race Fueling Guidelines

Proper race fueling is critical for endurance events. Your body can store roughly 90-120 minutes of glycogen, after which you need external fuel sources to maintain performance.

  • Start fueling at 30-45 minutes into the race
  • Practice your fueling strategy during training
  • Never try new nutrition products on race day
  • Take gels with water, not sports drinks
