The T-3000 test is a great non invasive method to evaluate the progress your athletes are making. It can be done in two ways. In the first method, athletes can swim for 30 minutes and record the distance covered. In the second, athletes can swim a 3000 m time trial. Whichever method is used, the effort should be maximum and evenly paced from start to finish. The results are then converted to an average speed per 100 m by dividing the distance swum in 100s into the time for the entire swim in seconds.
