I may not be the fastest swimmer in the world, but my love for swimming the IM maybe one of the greatest. The IM consists of doing the Butterfly, Backstroke, Breastroke and the Freestyle (in that order) for one, two, three or four X kilometers. Just as a runner finds their stride, with each stroke, the trick is to get into the rhythm, settle into a speed, lock it in gear the meters will slide by. That is how I love to swim.
