The amazing 3-day bikepacking adventure North of San Francisco

We are doing a 3 day bike packing trip to the north of San Francisco. Day1: Take Caltrain from Sunnyvale to SF, and start riding across the Golden Gate Bridge to Sausalito, then onto Mill Valley to load up food and drinks, and climb about 1,500 ft to Pantoll Campground, which is at the base of Mt. Tam. That's 24 miles with about 2,300 ft of total elevation gain. Day 2: From Pantoll Camp to Bolinas, then onto Point Reyes Station to load up food and drinks before climbing to Sam Taylor SP Campground. That's 36 miles with about 2,100 ft of total elevation gain. Day 3: From Sam Taylor SP to SF with a lunch stop at Fairfax. That's 24 mi with about 2,400 ft of total elevation gain.
