The way points of this bicycle route:
start at livorna park. This route not recommended -- the flaw is doughterty valley rd, which has too much traffic, inadequate shoulders, and too many lights. Probably a better choice is to go farther out and take Camino Tassajara; shorter alternatives are San Ramon Blvd all the way back (boring), or maybe the side roads on the east side of the freeway.
go straight for longer, easy path; go left for nasty but short 20% section!
Left on Heyer. There's a brief nasty bit getting over to Cull Canyon
