Thanks for such a quick reply and a warm welcome.

I'm very sure there will be nicer bikes than mine, but mine is no slouch either (Trek Madone 5.2) so the thought of leaving it alone is a little scarry. Especially when hearing stories of bikes being stolen when they are 3 feet away from the owner who was having coffee with friends.

This is the Davis, CA challange and I will be doing the 70 miles. I would love to meet up with some ladies that are doing this ride, even if we don't hang together for the entire time. My husband will be with friends, but I just don't feel strong enough to do all the climbing the 100 will require.
