Athletes are assigned wave start times by the organizers. Participants must check in at least 45 minutes before their assigned wave or risk forfeiting their spot. Each swimmer will start in an assigned pool lane; each athlete has their own lane. Any stroke may be used in the swim; walking is allowed if feet can touch the ground. The bike portion uses assigned stationary Keiser bikes; setting seat height and warming up are part of transition time. There is no standing on the bike - a first violation is a warning and a second may result in disqualification. Run laps are recorded in full and half laps, with 10 laps equating to 1 mile. Volunteers record distances and athletes sign a distance card after the run to verify results. Visit the organization's website for the most recent information.
