san rafael (aka home) to alpine dam. (
this map is actually to the west peak, which is a little over a three hour ride, but you can cut it down to just under two and a half by stopping at the damn and turning around, which is what duncan and i did yesterday 20-25 miles, 1500-2000 ft of climing)
san rafael olema alpine lake loop. (
this map only covers san rafael to olema, from there you have to ride south to fairfax/bolinas road and return on the alpine damn run. 50 miles or so, 2500-3000 feet of climing, the bulk of which is one grade (about 6.5% grade) from highway one to the west peak of the alpine damn run)
water is hard to come by on the alpine damn run (there is a spring or two, I've never drunk from them) but fairfax has great coffee and olema has a small general store with cold water. I usually stop in the store to replenish on bike fluids and treat myself to a coffee on the way home in fairfax.
