OBJECTIVE: To describe the incidence of injuries and other health problems sustained during participation in a marathon. METHODS: A cohort study was undertaken involving the 1993 Auckland Citibank marathon participants. Demographic data and information on injuries and other health problems sustained during, immediately after, and 7 d following the marathon were obtained from a pre-race questionnaire, the medical aid posts, and a post-race questionnaire. RESULTS: Of the 1219 starters, 916 (75.1%) completed both questionnaires. Seventy five individuals (6.2%) sought assistance at the medical aid posts. During or immediately after the marathon, 283 systemic health problems were reported by 218 respondents (23.8%) and 2671 specific health problems were reported by 846 respondents (92.4%). In the 7 d following the marathon, 1905 specific health problems were reported by 723 respondents (79.2%). The majority of the specific health problems were blisters, stiffness, and pain, predominantly involving the lower limbs. CONCLUSIONS: Although a high proportion of participants experienced health problem during the race, very few of these problems were serious. Many of the entrants were still experiencing problems 7 d after the marathon.
