Transition area

From Openwaterpedia

noun - Transition area is a staging area for a triathlon or multi-sport event (swim-bike, bike-run, swim-run, orienteering race, adventure race). Athletes and a few officials are usually the only individuals allowed in the transition area. Athletes enter transition areas two times during standard triathlons: T1 occurs between the swim and bike; T2 takes place between the bike and run.
