This mostly paved bike trail alongside Alpine Road is great for bike commuting — just don't run over any slower trail users! The trail runs all the way from Portola Valley to Stanford, offering some nice shade along the way. The brief moments of unpaved trail are near the Portola Valley end.

This fantastic tavern, founded in 1852, is the second oldest in the state. It features a large, beer garden-style outdoor area with plenty of shade. An extensive beer and food menu makes it a perfect stop to enjoy a brew and some great food after a ride.

While this is an expressway, there is good room for safe riding and most of the day it isn't too heavily trafficked which makes for a great, rolling straight run
