Episode notes
High-Carb Fueling Is Ubiquitous In Marathons
- High hourly carbohydrate intake (100–175 g/hr) is now common among elite marathoners and influences race performances.
- Adequate fueling has become a prerequisite for competing at the top road-marathon level.
Practice High-Carb Fueling With Bottle Rehearsals
- Practice high-carbohydrate race fueling during key long workouts and rehearse bottle handling for race logistics.
- Build tolerance by simulating race feeding to improve race-day GI and execution.
Doping Accusation Cleared By Complex Evidence
- Imogen Simmonds was cleared after a positive test blamed on partner-transferred substance and hair tests that implicated him but not her.
- The case illustrated complex, emotionally fraught anti-doping investigations for athletes.
