20 miles Wednesday morning to check out some drivetrain modifications. Beautiful sunny and cool morning in the 50s, just enough to be comfortable in a thin long sleeve Champion t-shirt (I don't have any proper long sleeve cycling jerseys... yet). Legs felt great after a two-day rest, rode one of my fastest times on a familiar roller coaster route and still had some in the tank. Didn't want to blow it all this morning because I might join a group ride this evening.
