Race Information
Get ready for some fun in the sun and a great mid-season test of your training at All-Out's annual Dog Days 5K, 10K & Half Marathon! Centrally located between Denver & Boulder and along with its Endless Series sidekick in December Fa La La, the beauty of the breathtaking Flatirons as a backdrop will inspire you every step of the way along Big Dry Creek Trail, well known as a Colorado favorite! This trail is great for dogs with a large amount of soft surface adjacent to the concrete path. There's even a dog division at this event to award the fastest dogs at each distance and a dog-themed costume contest!
