Pace/Rate = Pace and Rate are used to express your speed. Typically expressed as:
T1 - This is the amount time you spent in the Transition Area after the swim
T2 - This is the amount of time you spent in the Transition Area after the bike
Swim Time - This time typically includes your swim + the amount of time it takes to reach the Transition Area entrance.
Bike Time - Your time begins when you exit the Transition Area (after the swim) and your time ends when you re-enter the Transition Area (after dismounting your bike)
Run Tim - Your time begins when you exit the Transition Area (after the bike) and your Run time ends when you reach the finish line
