You Can Bike Commute to San Francisco!

What is pen2sf?

pen2sf is a group of cycling commuters that bike north from the southbay/penninsula toward San Francisco. We ride similar routes as SF2G, but in the reverse direction (reverse sf2g). Some commute home via bicycle, but most return via caltrain.


There are two main routes to bike to the city including an option along the bay and through the hills via skyline.
