Flagpole,
You have made some valid points, I think where me and some other people disagree with you is on it being a yes or no proposition. You are absolutely correct in that sometimes a coach needs to coach from sidelines and that kids should have some time together without the coach, especially female runners. I once knew a coach who was a competitive age group road racer. This coach basically ran what he wanted to run for his benefit, which was mostly a lot long slow stuff, which wasn't optimal for HSXC. FTR, H.S. kids don't need to do 7mpm 10-15 mile runs everyday. On the other hand, I got into coaching when I was in college and during the summer a group of H.S. kids started running with me. They asked me help coach their XC team. I became an unofficial volunteer coach and went on the majority of the runs with those kids. One of those kids placed 4th at his state meet and ran in the FL regional qualifier. He didn't even qualify for the state meet the year before; he credited running with me for his big improvement. When I became a full time coach, I didn't run with the kids too often, but when did, it was usually when they asked. Yes, sometimes the kids would ask me to run with them. Over time, I pretty much stopped running with my athletes, but that was mostly because I had bigger coaching responsibilities, I was I coaching older athletes and I was too slow.
Hopefully you get my point and we can end this thread.
