Transition in sports such as triathlon and adventure racing involves an athlete traveling from one segment of the race to another. These segments include swimming to cycle (T1) and cycle to run (T2). Transition does not form part of actual race time but is timed and can significantly influence overall performance. A swift and seamless transition can make one win or lose in a closely contested race.
Transitions in a triathlon are perceived as distinct events requiring mental and physical preparation. T1 is transition from water, and in it, athletes exit out of water, peel off a wetsuit if applicable, and prepare for the bicycle course. This often includes donning a bicycle helmet, bicycle shoes, and retrieving the bicycle from the rack. T2 is transition 2, where bikes are returned to storage and helmets are removed, and athletes exchange into running shoes that have elastic or speed laces and begin running. Every transition has procedures, and top professional triathletes rehearse these procedures repeatedly. Outside of triathlons, in ultra or adventure races, “transition” might also refer to spots where sports can change, replenishments can be made for supplies, or even medical aid is available. Wherever in long events transitions occur, they reflect on just how efficient, organized, and composed athletes can remain despite exhaustion, and are an integral part of race performance and planning.
