Understanding GI Distress in Ultra Running
Gastrointestinal (GI) distress, particularly nausea, is a significant issue among ultra runners, impacting race performance and leading to many non-finishers. Studies indicate that nausea is one of the most common reasons for dropping out of races like the Western States 100. The prevalence of GI symptoms highlights the need for further exploration into the causative factors behind this distress. Research reveals that mechanical factors, such as the jostling associated with running, play a prominent role in exacerbating these GI issues compared to other endurance sports like cycling or swimming.
