Back in highschool. We had a mean ole lady coach. MEAN!!! I was all into sprints and doin hurdles until I started for her. This woman realllllly wanted me to do long distance. So what did she do.....??? she set the hurdles up backwards and told me to run them. Ok....hurdles don't turn over if you touch them when they are backwards. After clearin a few....and noticin that. I stopped right there and asked her why they were backwards. She told me it was to build character. I flat told her right there, "no that was to build scars on your knees and hands when you crash and burn." No desire to crash and burn without good cause......So I gave the long distance a try as well.....first day out....12 miles. Haha, not much runnin went on that day.
Didn't take but about a week for me to figure out I in now way shape or form was cut out to be in this woman's program. She was nuts!!! I loved runnin back then....but not for her.
Congrats to your kiddo's tho......It takes lots of self disipline to do what they are doin.
