Ride up and over Mt Hamilton and out along San Antonio Valley. Then return the same way, except we do the lower descent up-then-down Quimby. Water available at Mt Ham summit (miles 22 and 47) but no other services so please bring enough food/nutrition.
If we are feeling energetic we could extend to the Junction for an additional 12 miles. To shorten, you could skip San Antonio or Quimby. [Route/Map]
