· 1 min read
First published:
Research through: 5 June 2026
A May review brings together trail-race fatigue studies. This is background available by this Friday, not a new June experiment.
Selected research available by this Friday; older studies are background, not weekly discoveries. Assessed in October 2026; screening was not exhaustive.
Topics: Recovery
Finding
The review identified both central and peripheral contributions to trail fatigue.
Limitations: Mechanism depends on race duration and testing method.
Evidence level: Moderate evidence
Finding
Peripheral fatigue and muscle damage were more evident in longer events.
Limitations: Different tests and populations prevent a universal distance threshold.
Evidence level: Moderate evidence
Finding
Sex comparisons were sparse despite the large combined sample.
Limitations: Few direct comparisons cannot establish equivalence.
Evidence level: Moderate evidence
Interpretation
Ask what was tested, when and in whom before transferring a fatigue result to your race. No recovery timetable follows from this review.
