How many hours of swim practice would it take to lop two minutes off your swim time? Probably hundreds, maybe even thousands. How many hours of transition practice would it take to lop two minutes off your transition time? Maybe only one!
Many triathletes are so focused on swim, bike and run splits that they forget the clock is still running in the transition area. Every second counts. Transition practice isn't as fun as running, but it is a good investment of your training time.
The transition is not a rest area but a place to speed in and out of, in the fastest time, with the least energy.
