In 7th grade I ran track for a season (badly), and never did break the 5 minute mile goal coach set for the team.
Last year, and again early this year (May), I pulled down a sub 7:30 mile, and I thought it would flat kill me.
I'm forty three. One thing I think I see a lot of is guys who were athletes in middle school, high school, and even college, who are now in their middle years, continuing to ride on their numbers from their salad days.
What have you done lately. I'm really interested in what middle aged guys can, and can not, do.
