Your prep training depends on what you will be doing during the season but you can always benefit from just eating healthy, stretching and conditioning. It's best to split time between sprints and distance running so you condition all of your muscles.

what ever u do after u run dont sit down i is not good for your heart

Run!!!

staggered training daily on elliptical and stationary bicycle - moving to training with rubber waist bands at the end of the workout when fatigued before going to repetition sprints on a tract....works for the high schools here when athletes are late in joining or due to conflicts...
