We rode Sawyer Camp Recreational Trail today (soon to be named Crystal Springs Trail) in San Bruno. We didn't realize that the exit to take on Sundays was Black Mountain Road but we eventually found the northern trailhead on Hillcrest so our route started off downhill.
It was a nice day for a ride, relatively warm and most of it was easy going with the exception of the last mile on the way back with about less than 500 feet of elevation gain. I was pulling the bike trailer and we had to walk a few sections of the last mile.
