Get creative with this colourful costume filled 12k. Great for runners of all levels, the course follows the historic 1912 route that San Franciscans ran to help rebuild the city's moral following the 1906 earthquake. Come for the physical challenge or for the vibrant fancy dress costumes.

  • Did the 12K in 2014

    Pretty great time! Only year I actually finished the race though, the other years I tended to get side tracked by brunch.
  • Did the 12K in 2017

    Be prepared for a crowed high energy run that feels more like a party than a race! Most participants run in clever costumes, but it is not required (clothing in general is also not required). You will be cheered on for the entire race since a mass amount of people come to watch the run too. At the starting line, runners are grouped into corrals based on mile pace and you are sent to start from fastest to slowest. Be prepared to wait quite a while if you have a slower mile time.
  • Did the 12K in 2019

    What an amazing day! My first Bay to Breakers, and despite the rain in the morning., lived up to the hype in terms of atmosphere and organization!

    What exceeded expectations though was the actual run. I knew it would be a lot of fun, but kind of thought would get stuck in traffic, and not ultimately post a good time. Should you want to push yourself though, it is actually a great course, with plenty of space if you start in the right group, and a great mixture of flat and hills to test yourself! Definitely doing again!
