Hummingbird Fuels: Hamilton Diablo Double Shot Route

Cycling Route

Details
118.53 mi
11,307 ft
Welcome to the fourth edition of the annual Hummingbird Fuels: Hamilton Diablo Double Shot.

Hummingbird Fuels is excited to host this event and will have fuel at the start and midway on Mines road (at The Junction) right where you'll need it ;)

ABOUT THE RIDE:
This route leaves from the Pleasant Hill/Contra Costa BART station and takes riders up Diablo.

We then descend into Livermore where you can grab lunch (Lisa's personal fav will be McDonalds ;). Before we tackle the rolling hills up Mines Road, hit the Hummingbird Fuels Re-Fuel Station at The Junction, and then take on the final climb of the day—the backside of Hamilton ( a 10% average grade).

Once you finally make it to the top (where the observatory is) you'll find washrooms, a water fountain and some vending machines (better than nothing haha).

Wash the salt off your face, take some celebratory pics and put on a jacket before your final 20 miles.

Your reward for all that climbing, is a buttery smooth, flowy descent into San Jose where you can grab public transit home (the Berryessa/North San Jose BART station is just a few miles away).

This is not easy. But it is fun. We hope you'll join us for the greatest (new) Bay Area tradition.
