Race Course

In 2014, the Crescent Moon Triathlon will offer the choice of sprint or Olympic distances.

SWIM (Map): Sprint distance swimmers will complete a 750 Meter rectangle-shaped swim in crystal clear Aurora Reservoir, starting and finishing on the sandy beach adjacent to the swim area. Olympic swimmers will swim an extended version of the sprint course. The start will be in waves which will be posted at packet pick-up and on our website 1 week before the event. Water temperature in the reservoir in June is typically in the mid-sixties, so wetsuits are encouraged.

BIKE (Map): The 20K bike course is rolling, with miles 2-10 on a road that is closed to auto traffic. Olympic cyclists will continue approximately 6 miles beyond the sprint turn-around, to a turn-around of their own. The Olympic course will be 40K. Drafting is not allowed on the bike course, and motorcycle marshals will be enforcing this rule.

RUN (Map): The 5K (3.1 mile) sprint run course is a loop course on a mix of bike path and well-maintained non-technical dirt running trail. The 10K Olympic course will split from the 5K loop at approximately 1.5 miles, and do a 3-mile out & back segment, before joining the 5K runners for the final 1.5 miles.

Aid Stations There will be two aid stations on the 5K run course, and five aid stations on the 10K course. All aid stations will be serving ice cold water and HEED energy drink. There will also be two opportunities for 10K runners to take gels on the run course.

TRANSITION (Map): The transition area will be located in the upper parking lot at the Aurora Reservoir, just above the finish line and expo area.

Relay Teams will receive 1 timing chip which must be transferred from swimmer to biker to runner. This exchange will take place at a designated are within the transition near the bike-in/bike-out location. Timing chips are attached to a soft, comfortable Velcro strap which must be worn on the ankle.
