=v= I'd like to make some friendly amendments to that route.
Folks may want to take a look at or print a portion of the
big SF Bike Map available here (in PDF format, 2.0MB):

(1) I wouldn't take Fell from Market to GGP. City planners
were thwarted from putting a freeway through GGP in the 1960s
so instead they made Fell a multilane one-way road with lights
timed to encourage speeding, and it's a very unpleasant ride
up and over the hill with cars going 50+mph.

The much more popular route is to take Market uphill a
bit and turn right at Duboce, then take the city's one and
only bikeway for one block behind the Safeway (alongside the
Bike Mural), then follow a path called The Wiggle (it's the
sort of wiggly line on the SF Bike Map). This is the route
of an underground creek, and is the flat path connecting the
east and west sides of the city.

This will get you to Fell, though you've got three blocks
of bike lane (formerly three blocks of guerrilla bike lane)
to the GGP Panhandle. Beware of the cars speeding down the
hill, and also the overflow from two lower-price gas stations,
which often blocks the lane.

(2) Speedway Meadow is in the northern part of the Park, so
once you get to the Panhandle you'd just cross the street
and go essentially straight ahead onto J.F.K. Drive, which
has a bike lane for a stretch. Don't continue on Kezar as
it turns left (as is indicated at the Bikely link).

=v= Alas, I'll be out of town this weekend, but I really
enjoyed Tour de Fat last year. Valet bike parking was
overflowing, so we locked our Bike Fridays nearby:

On the way out I saw a guy with a Tandem Two'sday:

P.S.: I'd update Bikely myself but I appear to have too
much privacy turned on in my browser right now. :^)
