Injuries in a 1-Day Recreational Cycling Tour: Bike New York

Study objective: To describe injuries during a 1-day urban cycling tour. Methods: During the May 1996 “Bike New York” tour, we monitored EMS calls to identify injuries in a cohort of helmeted cyclists shielded from traffic. We collected demographic information from entry records, injury data from ambulance call reports, and follow-up on transported patients from telephone interviews with emergency physicians. Data were summarized using proportions, relative risks (RRs), 95% confidence intervals (CIs), and χ 2 Results: Approximately 28,000 cyclists participated, of which 23,502 (84%) were officially registered. Sixty-eight percent of registered bicyclists were male, and 92% were between 18 and 55 years old. Of the 140 EMS calls made during the tour, 136 (97%) involved participants; this yielded an injury incidence of 5 per 1,000 riders, or 12 to 13 per 100,000 person-miles. Injury was more common among younger cyclists (RR=1.4 for age ≤35 years versus age >35 years; 95% CI, 1.0 to 2.0; P
