Looks like this is going to be a very fun race at Glorieta Camps (east of Santa Fe) on August 9th.  It will be a good one to "tri" for a first-time XTERRA.

There are also options for relays if you don't do one of the disciplines.  You can contact the race organization and they'll help get you set up with folks who can join you for the relay.  Come on...it's only 750 meters of swimming!
