The Sprint Trainer (software) allows the swim coach to have the functional task of the timing of the workout sets done by the computer. It sets the swimmers off, keeps the interval on the correct timing, accurately times and gives the swim times to the swimmers, restarting the next repeat on time, keeping track of the number of repeats and informing the swimmers of their performances in relation to the other swimmers doing the set. This allows the coach to "actually do some coaching" with these swimmers or even to work with another group as the computer runs this part of your workout.
