Its not too late to register for this one! http://www.clarksvillecentury.com/ I will be doing the metric (62 mile) century at an intermediate pace ~ 15 mph average. The Metric starts at 8 AM. I will be outside the registration area at about 7:30 AM on a Black Raleigh, Grey Ride615 kit and red helmet.
Only 1350 ft of vertical!
