Practice Fueling and Gut Training
Fueling works when it has been practiced under relevant conditions, not when a race-day number is copied from another athlete.
Build a race fueling plan that the body can tolerate and execute.
Match the distance
A half marathon may need a simpler plan than a marathon. Duration, intensity, weather, and personal tolerance determine how much fluid and carbohydrate are useful.
Train the gut gradually
Practice planned intake during selected long sessions, beginning with an amount that feels tolerable and increasing only when the response remains good.
Treat high intake as advanced
Very high carbohydrate targets require product testing and adaptation. They are not universal minimums and should never be attempted for the first time on race day.
Put it into practice
- Choose a simple race fueling draft.
- Practice it during selected long sessions.
- Record intake, comfort, energy, and recovery.
The planned intake feels familiar and supports the session without repeated gastrointestinal problems.
Very high carbohydrate intake is an advanced option, not a universal target. Increase gradually and never debut a plan on race day.
