Why the study?
To determine the incidence and nature of illness-related medical encounters at a 90-km ultramarathon mass community-based endurance running event.
The 90-km Comrades Marathon has a high incidence of medical encounters (1 in 52 starters), primarily related to fluid/electrolyte and central nervous system issues, emphasizing the need for preventative strategies.
No takes yet. Share an insight, caveat, or question.
High ME rates at ultramarathons require strengthened on-site preparedness; extends observational data on endurance illness burden for targeted prevention research.
Sewry et al. (2021) studied this question.
