Research through: 19 June 2026
A qualitative study published on 18 June follows five Marathon des Sables runners through preparation and aftermath. Interviews explain experiences, not which diet works best.
Selected research available by this Friday; older studies are background, not weekly discoveries. Assessed in October 2026; screening was not exhaustive.
Topics: Fueling guide
Finding

Finding
Gastrointestinal experiences ranged from mild discomfort to severe symptoms.
Limitations: Self-reports cannot isolate the cause or estimate prevalence.
Evidence level: Moderate evidence
Finding
Psychological challenges became part of participants’ race accounts.
