The purpose of this set is to challenge swimmers by having them swim at paces and for distances that gradually approach 200 race pace. When we did the set, we started with 175s all freestyle, and then progressed to the 180s and beyond done as athlete’s choice of stroke. Swimmers were timed to a hand touch on the 175s, and then were timed to their head breaking the line. We used a cone on the side of the pool and multiple cones on the bottom of the pool to mark the required distance. Our swimmers were very successful making the goal time (lifetime best time) all the way through the 190 yards and several were successful at the 195y distance.
