Hi my name Rick, I just ran a 6.8 mile/min. over an 8.3 mile course. I can run longer routes, if needed. I am 61 yrs. young and in great shape. I prefer level, or up hill and I always have run in the middle of the night. That, of course can change. Let me know if you have an opening. I havn't run in this before, and would like to try it out.
