Some events provide a relay pen, which is designated for the teams to gather. This is where the timing chip is passed, to move on to the next discipline. If the race provides a relay pen, only the cyclist is allowed in transition, he/she must have the chip from the swimmer before un-racking the bike and must rack the bike before passing the chip to the runner. If the race does NOT provide a relay pen, the cyclist and runner will meet their team members at the bike rack. The biker must have the chip from the swimmer before un-racking the bike and must rack the bike before passing the chip to the runner. Please make sure to coordinate with team members regarding estimated times so members are not loitering in transition during the race.
