Endomondo is the shit... not only is it great for cycling, it works for pretty much every other sport out there.
My dad did the 100 mile on the Wright Wride today, I just went out for a few miles with the fiancee.
Also to the night ride comment, Evan just get a nice set of lights, probably in the $250 range and you will love it, best time to ride IMO. No traffic, cool etc.
I would love one of these....

2600 lumens...
Yes its brighter than car lights.... and really good for mountain biking, but would work great for the road too!
To buy them, (you don't wanna see the price) http://gretnabikes.com/lupine_lights.asp
I had a HID light, with an actual ballast and everything. It was a $500 light and a hand me down from my dad when he upgraded... bright as shit, but it died finally.
