i expect a good turnout for this ride since it is being advertised on several listserves (well assuming people check their email this morning and can get there by 9am).

It's quite possible there will be "slower" riders, but not a given. Come prepared to have fun! Who knows - maybe you will find someone that will challenge you to ride a little faster, or maybe you can challenge someone who is a little slower than you to push herself to new limits.

Just be careful and bring plenty of food/water for the 63 miles. Also have some ID on you and an emergency contact.
