I the last two weeks, I used the opportunity of lighter traffic to try to commute by bicycle from San Francisco to San Mateo.
I mostly followed the North-South Route Map that is available on the Peninsula Bicycle & Pedestrian Committee.
My exact complete route is 23.1 miles long door-to-door… and it takes me about 2 hours to complete. I have mapped it on veloroutes.org.
Here is also an image of the elevation data.
