Rock n Roll San Jose

Organised by Rock n' Roll (who organise over 30 events across the world), this event has something for everyone. There is a half marathon, 10k, 5k, and a kids race option.

Run through the "Capital of Silicon Valley" and enjoy this quirky high tech city. With easy access to California, you might want to make this trip a short one as the area has an extremely high cost of living. 

Run the race, enjoy the atmosphere, visit Google (in real life), explore the Winchester Mystery House, and get out ;)
