SF to Rodeo Beach on Bike

Rode bike to Rodeo Beach (Fort Cronkhite). Click on images for larger views. Starting and ending point are at the lower right of the map, and elevation graph tracks accordingly.I joined tracks that were disconnected by going through a tunnel. I think the red zone on the outbound, the signal was blocked by a hill coming out of the tunnel, which didn't happen on the return. Of course, it could just be that I made an error joining tracks, but this looks about right. Outbound, uphill in the tunnel is a bit freaky, since you can't keep up with cars, and before the end, you have cars coming at you in close quarters (but there is a bike lane).
