Sorry to be "that guy", but does anyone have any knowledge of middle distance/long distance running, particularly at the HS level? Puberty caused my son to lose about 40 lbs and he went from being a middle of the pack slogger in running to someone who seems to be quite capable. He decided to drop water polo, which had him in amazing shape, and is willing to train for track to keep up his conditioning (in addition to wrestling stuff and football stuff, which tie him up for 3-4 days a week in the first half of summer. I'm trying to figure out what distances he should be thinking about somewhat seriously and from there any thoughts on good resources for training plans. Thanks all.
