Get ready for the best race ever! The San Francisco Challenge urban adventure race is returning to the City by the Bay for our sixth season on Saturday, March 21st, 2015!

The Challenge is a ridiculously fun “Amazing Race” style competition packed into one incredible day. Teams of two or more will dash around the city, racing against other Challengers for immortal glory (and cash prizes!) as they solve tricky clues, strategize the best route, and explore undiscovered corners of the city.

Think of it like a 5K that tests your brains as much as your legs, with bigger prizes and a whole lot more fun--we guarantee you’ll have a blast!

  • An amazing, active way to get outdoors on a Saturday and explore your city with friends and family in San Francisco!

  • Don't worry—fitness is a plus, but you’ll need a blend of smarts AND speed to win this race!

  • At the finish line, we’ll welcome you back with cash prizes for our winners, cold water for all, food and drink specials from our venue, finishing with our our crazy costume contest and awards ceremony!
  • Take it to the next level: the top 50 teams from this race will qualify for our Challenge Championship event at the end of the season in New Orleans--with more than $6,000 in prizes at stake!

If you’re ready to take the Challenge, grab some friends, pick a clever team name and sign up right below! For more information, read our FAQ or contact us with any questions.
