Format and logistics
Each swim starts with athletes assigned to individual lanes; any stroke is allowed and athletes may walk if their feet touch the pool bottom. There is a 15 minute transition period from swim to bike and a 5 minute transition from bike to run for both divisions. The bike portion uses assigned stationary bikes (Keiser); athletes must set seat height and warm up during transition time. Standing on the bike is prohibited; the first violation receives a warning and a second violation leads to disqualification. Run distances are recorded in laps and half laps, with 10 laps equating to one mile. Volunteers record distances for each segment and athletes sign a distance card after the run. Wave start times are assigned and will be posted and emailed; athletes must check in for their wave at least 45 minutes before their start time. Athletes receive a goody bag.
