The 100 IM is the most fun event on the Masters swimming short course schedule. Takes you back to being 9 years old again.
We should add it to the long course schedule. Who really needs a wall to change strokes? The rule could be that the swimmer must change from fly to back and from *** to free in a transition zone in the middle of the pool. The zone could be markers on the lane lines or the transition must begin when the head reaches a marker at 25m and must end before the feet pass the same marker.
Good idea or impractical?
