My favorite centuries:
Spinning Through Time
Covington
Wilson 100
Six Gap
MACC's One Love
Share The Road
Beautiful Backroads

Plus, there are always un-supported centuries. I'm sure we'll be running a few that we'll post here, and the folks on the sbl forum do some. Look for the Land Of Sunsets ride that they do - it's an easy route off the Silver Comet.

The way things are looking, a Silver Comet century is just a few weeks away from being possible.
