Cycling Glossary - Word of the Day

transition

1. The point at which the lip/landing of a jump changes from a vertical to a horizontal surface. 2. In the sports of triathlon and duathlon, the transition comes between each racing leg, such as after the swim and before the bike leg. How quickly you "transition" (changing into your cycling clothes and mounting your bike and/or getting into your running gear) affects your time and result.
