OBJECTIVE:

To report the number of marathon finishers younger than 18 years and race day medical encounters at the same site and to compare them with adult finishers.

DESIGN:

Retrospective cohort study.

SETTING:

Urban 42-km road race.

PARTICIPANTS:

Twin Cities Marathon finishers.

ASSESSMENT OF RISK FACTORS:

The race records from 1982 to 2007 were assessed for finishers younger than 18 years to determine the number of finishers and medical encounters, incidence of race-related medical encounters, and type and severity of medical problems.

MAIN OUTCOME MEASURES:

Age group marathon finishers and medical encounters.

RESULTS:

Three hundred ten marathon (225 boys and 85 girls) aged 7 to 17 years finished the race with times ranging from 2:53:22 to 6:10:00. There were 4 medical encounters (minor in nature and required no intervention beyond a short period of rest) for an incidence of 12.9 per 1000 finishers. The odds ratio for youth compared with adult finish line medical encounters was 0.52 (P = 0.2658; 95% confidence interval, 0.19-1.39).

CONCLUSIONS:

Three hundred ten youth marathon successfully finished Twin Cities Marathon over 26 years with only 4 requiring post-race medical evaluations. The relative risk of requiring acute race day medical attention was less than, but not statistically different from, adult finishers.
