Your welcome buddy.
You make a good point. There are definitely track meets during the week. That changes things. And correct, the only team aspect is relays and training. Training as in competition benefits you, similar to football. You will improve more from practice when you are racing your teammate who is just as fast or faster than you than you would by yourself since at the collegiate level, most are alpha males and competitive.
In terms of training and your comment about time off being beneficial, the important track meets are the conference championships/national championship meet. Good coaches will design training to have the athlete peak during the end of the year. This means, that you want to lay off on intense training towards the end so the athlete is fresh and is peaking at the right time.
Not sure if thats the way to go in football but I could be wrong. Feel like consistency and rhythm is extremely important throughout like echo said. If you lay off at any point, bad things can happen. You know, things like.....losing to northern Illinois....
In track, you do bad one week and run a bad time, whatever. Put it behind you and learn from it. Only your best performance of the year matters for seeding in the championship meets.
