Swim

In training for a triathlon I may never do I swam for the first time with swim training in mind. At the Valois Pool I swam four laps (note, a lap is defined as swimming the span from one side to the other, so four laps means start on side A, ->B, ->A, ->B ->A). I then took a three minute break, swam four laps again, took a five minute break, and then swam six laps. The six laps I swam in about 200 seconds. I need to find out what the distance is of each lap, as I am working my way up to get to 750m. Mind you, I won't be in that pool for much longer as the summer is wrapping up soon.
