The way points of this bicycle route:
This loop can be taken either direction. The Norris Canyon peak is higher, but the climb from San Ramon up Crow Canyon is steeper. Counter clockwise is much harder than clockwise. About 930' elevation change in 8 miles a lap is good work. Toss in a trip up and back Bollinger for a long sustained climb. http://www.bikely.com/maps/bike-path/Bollinger-Canyon-Dead-End It's 4.4 miles and 520 ft of steady uphill.
