I think of myself as the lone ranger of bike riding but I am interested in doing my state's Tour de Cure, a benefit ride for diabetes. It is, in this state, not a race, it's a ride. I thought I would do a 25 mile ride, which is well within my capacity. What do I need to know about charity rides? Since I don't ever ride with other riders, what do I need to know about riding with groups of riders? Any helpful hints for what to expect on the day of the ride?

my newbiness is showing...
