Need biking help on the exercise board.

There is a girl who posted on the exercise and fitness board about a 109 mile bike ride.  I thought someone here might be able to help more than I.  Thanks http://www.obesityhelp.com/forums/fitness/a,messageboard/act ion,replies/board_id,5104/cat_id,4704/topic_id,3431268/ By the way, for all you fitness guys, come and check out the board.  It's gaining a little momentum.  At least in the running department.
