This is a bit of a crazy climbing ride. Not Mark Lowe crazy but very challenging nonetheless!
We'll meet at the lot across from the Boulder Justice Center at 7:00. We start by climbing the first 4 miles of Boulder Canyon ( the reason for the early start time--get that out of the way before traffic really gets going) and then head up Magnolia, which is the steepest climb in Boulder County.
At the end of that 4 mile climb the road does turn to dirt for about 7 miles. The dirt section is not very challenging climbing-wise and is rideable on a road bike, but of course wider tires (e.g. 28) are preferred over narrower ones (e.g. 23mm).
We'll then hit the Peak-to-Peak highway and turn to head up to Eldora. We'll drop into Nederland to refuel and then head up to Ward and Brainard Lake. We'll return via Lefthand and Lee Hill.
The route is 68 miles with 8300 feet of climbing. Very challenging with lots of spectacular scenery!
