Running from one end of the beach to the other, and back.  Started at Vincente street on ocean beach (San Francisco, Ca) to mussel rock park (Pacifica, Ca; End of beach) to sutro baths/lands end (San Francisco, Ca; End of beach) back to Vincente street. 

Start on the South side of HWY 4 and follow the fire road which leads to the start of the CPR trail. Go up on CPR trail, stay left at T intersection (towards CPR lookout) and follow until you pop out on logging road leading to old ski parking lot. From there, go to the summit of Cokely and return back HWY 4 intersection where you started. FKT route is flexible as some may decide to go right at T intersection when ascending. The same can be said for coming back down - choose your own adventure.

From Stanford street parking lot gate to the peak and back down.

Both start and finish are marked with information boards, and along the entire trail there are orange-painted piles that mark the distance.
