Sorry, I wasn't online last Friday.
That would be a LOT of easy miles!
I'd probably go north via
Interstate (a couple hundred feet of Interstate will not be easy mileage - big hill)
R at PIR
L into Delta Park (just after you pass under the freeway)
go straight all the way through the park
pretend like you just took the off ramp and take a left (northbound onto Union Court)
R on Marine Drive
Travel East for a couple of miles
R on 33rd
immediate R into parking lot
L under over pass and you're on the path.
