yeah i actually did best of my 5 friends, the others whom ride faster in group rides, mainly because of stop and go, came in a few minutes behind me up to 1 hr and 14 min. the other benefit was the no drafting rule we enforced, because they usually tend to sit and mash, sit and mash.
there aren't too many 24 mile straightaways in los angeles to run on, but i found this circular block that is about a quarter mile round. i'm going to attempt this again on sunday, and hope that i don't get too dizzy.
i can sit in and pull comfortably in fast group rides, i guess this is more for personal assessment.
anybody in LA area want to try this out?
