The Barkin' Dog Duathlon will offer the option to compete in the standard 5K/30K/5K format with a bike course that exits the park and crosses the Cherry Creek Dam Road, or the choice to race a shorter course (1 mile run, 15K bike(approx. 9.3 miles), 5K run). Start, Finish, and Transition are all located in the Swim Beach parking lot. Athlete parking will be in the Smoky Hill parking lot, just a minute walk from transition.

The 1st Run Course is a single-loop route that is gently rolling over paved park roadways and paved multiuse paths. 5K-30K-5K participants will complete the entire loop, which measures just shy of 5K (3.05 miles), while the short course participants will complete the first mile of the route, then turn into transition. An aid station is located at the half-way point on the 5K course.

The 30K Bike Course is a 30K (approx. 18.6 mile) out and back that crosses the park, exits at the west entrance and crosses the Cherry Creek Dam Road. There will be a turn-around at the east end of the Dam Road. From there, riders return to the park, and take a slightly different reurn rout through the park. This route has three moderate hills, and lots of flat-fast riding - especially the stretch on the Dam Road! The course is 100-percent paved. A map will be posted shortly.

The 15K Bike Course is a 15K (approx. 9.3 mile) loop that has two moderate hills, and lots of flat-fast riding. The course is 100-percent paved.

The 2nd Run Course is very similar to the opening 5K run, with the exception of the first half-mile. Runners will exit transition and jump immediately onto the paved park trail. Approximately one half mile into the run, you will merge with the first 5K run loop and contine on that course. Both 5K-30K-5K and short course participants will complete the same 5K second run. The finish line will be located just outside the transition area near the race expo. A map will be posted shortly.
