Evidence and interpretation
Evidence and transfer
The ISSN single-stage ultra position stand discusses intake, food tolerance and gut practice. Its scope is not a complete stage-race prescription. The existing high-carbohydrate marathon experiment does not establish a universal ultra dose.

Build a fueling rehearsal
Write a segment plan: foods you know, carbohydrate shown on labels, carrying capacity and the next resupply. Test it while moving at a representative effort. Record what you actually consumed and any GI symptoms, not just what you intended to consume. Change one variable before concluding a product is unsuitable.
Editorial practice · not a validated protocol
GI durability and fallback
In observational multistage data, GI symptoms were associated with lower recovery intake; this does not prove a specific gut-training remedy. Prepare familiar alternatives and an aid-station decision rather than forcing an increasingly intolerable plan. Persistent vomiting or serious deterioration warrants medical help.

How the fueling task changes
For a shorter 50K, check whether course duration is actually similar to your previous race. At 50 miles and 100K, rehearse repeated resupply. For 100 miles, include night access, changing food preference and crew handovers. In stage races, the next start makes meals between stages part of the plan; in continuous multi-day racing, eating and rest must coexist on the course.
Editorial practice · not a validated protocol
Avoid dose escalation by distance
Do not multiply grams per hour by a distance category, chase another runner’s record intake or use fasting to compensate for eating during a race. Individual requirements and tolerance differ. A sports dietitian can help when recurrent GI problems or energy availability concerns make a generic plan inadequate.
