Population

65,865 race starters (39,511 in 21 km races, 26,354 in 56 km races) participating in the Two Oceans Marathon races over a 4-year period.

Outcome

Medical complications (defined as any runner requiring assessment by a doctor at the race medical facility or a local hospital on race day)safety

Medical complications during distance running are relatively rare, with serious complications occurring at similar rates in 21 km and 56 km runners, though sudden cardiac deaths were only observed in the 21 km group.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Supports low event risk for medical planning; leaves open why deaths occurred only in 21 km runners.
