12 teams, all from Texas, are racing in Bistrop for 100 points in the 2nd Adventure length race of the 2010 Checkpoint Tracker adventure racing season.

Online coverage of the Big Chill includes a continuously updated micro-blog called Race Central and a Leaderboard that tracks each teams progress from checkpoint to checkpoint.

Checkpoint Tracker is a year long, nationwide adventure racing series made up of nearly 80 events produced by 35 of the country’s most successful event promoters.

Thanks to the support of our partners, including MPGear.com, Ultimate XC, MyTopo.com, Breathe Magazine, Numa Sport Optics, Swiftwick, nuun and SportMulti and Axis Gear, Checkpoint Zero, in partnership with Gravity Play Sports, will be producing the Checkpoint Tracker National Championship on October 29th in the Rocky Mountain Region.
