Check out this crazy bicycle scavenger hunt:
Over 800 riders in Austin TX a couple weeks ago. The Ft Collins race was a BLAST!!!
You and a teammate race to checkpoints around the city and do crazy obstacles at each stop. Then there's Fat Tire beer and Chipotle burritos at the after party!

Adult big wheels, inflatable slip and slides, hippity hop balls....

There are still 2 races: Denver (7/30) and Boulder (8/27).
