The first edition of the Crescent Moon Triathlon was held at the Aurora Reservoir as a part of the Harvest Moon weekend in 2007. The Crescent Moon Sprint Triathlon returns to the Aurora Reservoir in 2012 to celebrate its sixth anniversary!. This means crystal clear water for the swim, a fun 20K bike course with eight miles that are completely closed to auto traffic, a run that is also traffic-free, and a fantastic post-race and expo area, all with convenient parking!

Also an Aquabike in 2012!!!

The Crescent Moon will also be offering an Aquabike event in 2012! For those of you who chose not to run, the Aquabike offers the same swim and bike as the triathlon, and concludes with a 200 meter jog to the finish line instead of the 5K the triathletes will run.

The race is limited to 600 participants. Entries will be taken in the order they are received, and there will not be a waiting list for the event. Registration will close when our 600 participant maximum has been reached.

Refund Policy

Registration is now open! As always, there are no processing fees for online registration, and new in 2012 - there will be no additional fees for a USA Triathlon one-day license! USAT has raised their one-day fee to $12, which affects more than 80 percent of our participants. As a result, we have chosen not to sanction the event with USAT this year. In all, you will save nearly $20, and relay teams will save more than $40!!! Racing Underground has been coordinating multisport and running events on the Front Range for 18 years, providing well organized races with a reasonable entry fee and all of the perks including high quality tech-shirts in men's and women's styles, catered post-race meal, fast and accurate results, well marked and marshaled courses, more than $10,000 in prize money in 2012, quick and efficient packet pick-up, and amazing sponsor drawings at each event! All without the added cost. I hope we'll see you on September 15th for another awesome event!!!

Overall results with swim, bike, run, and transition splits will be posted at the event, and on this website on the afternoon of the event.

Each participant and relay team will receive a timing chip attached to a soft comfortable neoprene and Velcro strap. This is to be worn on your left ankle with the Velcro securely fastened. We recommend that you wear it under your wetsuit to avoid the possibility that it gets pulled off during the swim, or when you remove your wetsuit. You must be wearing your timing chip to receive split times and finish time. Timing chips must be returned at the finish line following the race or you will be charged the $97 replcement cost. If you decide to withdraw from the race, please stop by the finish area to return your chip before you leave.
