Sometimes it's hard to run in hot weather, maybe that's why.
Good coaches seem to treat indoor a lot like the summer, with some speed work towards the end to do well in championship meets. My high school coach was terrible, but at least it was always a fun season. My fitness at the end of cross country would carry through and I'd run fast times on this really intense track. The crowd is so close and right above you, the experience is pretty awesome.
Somewhere in the middle of the season it would wane, because we'd be doing stupid track workouts for months and you can't keep improving like that. Outdoor usually went poorly.
