Start the 2018 Multisport Season at the Barkin' Dog!
The Barkin' Dog Duathlon celebrates 20 years as the kickoff race for the summer multisport season! The Barkin’ Dog is Colorado's largest duathlon, and consistently one of the largest duathlons in the Western United States. The race spent it's first seven years in the small town of Keenesburg, just north and east of Denver, but we outgrew that location and made the move to Cherry Creek State Park in 2006.
This race attracts some of the top pro's in the country as well as a whole slew of first-time multisport athletes trying something different. If you can finish a 5K, you can complete a duathlon!
Participants can choose from the standard 5K Run, 34K Bike, 5K Run event or the short course which challenges participants with a 1.2 Mile Run, 11 Mile Bike, 5K Run.
