Best of 2012!

Posted on December 20, 2012 by Rattlesnake Tri Admin

RattleSnake Triathlon took the top spot in Competitor Magazine's annual competition (as voted by racers and athletes) as the top triathlon in Colorado. We are humbled and excited and are already thinking of things we can do to make 2013 even better. Thank you racers and volunteers for making the Rattlesnake Tri what it is. We think it's a race that is great for first timers and experienced racers alike.

New for 2013 - AquaBike!

Posted on November 16, 2012 by Rattlesnake Tri Admin

RattleSnake Tri in 2013 is launching a new category for those racers that want to race 'AquaBike'. You will have the option to race the new Crazy Back 2 Back AquaBike. Racers will start with the same swim and bike that others race but the run will be 100 yards to the finish instead of the 10k and 5k. We understand that not everyone can physically take the pounding on the knees so hopefully this helps everyone compete in 2013. Let us know what you think about this wave with awards for the top 3 overall. Note we will also for the first time, award the top three overall in the triathlon Back 2 Back and $1,000 for top elite and age group racers returns as well for the Olympic.

Volunteer

Posted on March 15, 2012 by Rattlesnake Tri Admin

We love volunteers. Usually you can pick the area you want to help in and you get the same great food the racers get and there's always some kind of swag, PLUS you don't have to get sweaty! If you have a group of 10 or more and want to staff an entire aid station, let us know that as we likely can wrangle up some type of donation for your group. Contact our Volunteer Coordinator for more information. Thank you for considering helping at the Rattlesnake Triathlon!
