    Get ready for the whackiest race ever in Durango! Purgatory Resort tubing hill. Run up. tube down. Repeat!

    Most laps wins!

    Oh, and it's a relay race!

    Team up with your best buddy for this tag-team style race. We will have male, female, and coed divisions for adult teams, as well as race categories for kids and parent/child teams. Teams must consist of two people in order to compete, but we will also allow three-person teams (like mom plus two kids) if you are just out for fun, not prizes and glory.

    This event is limited to just 40 teams, so sign up quick!

    And since it's Purgatory Resort, you know we will turn this thing into a party. We'll be spinning tunes while you race, high-fiving you each time you pass through the transition area, and giving out cool prizes.

    Feel free to wear a costume. Actually, you should probably wear a costume. (Yeah, it's that kind of race.)
