    Miles 4 Madison is a 5K/1K Fun Run supported by Sterling Ranch CAB. Miles 4 Madison's goal is to provide educational and recreational opportunities for families with children with different abilities. The Race is for all capabilities, strollers, and pet-friendly! Race registrations done after 9/10 won't be guaranteed the selected shirt size.

    After the success of previous years races, Miles for Madison provided scholarships for several Douglas County children to attend the week-long summer camp at Easter Seals Rocky Mountain Village as well as attend hippotherapy in Douglas County. We have been able to donate playground equipment to local schools and have hosted multiple sensory-friendly events in Sterling Ranch, including Sensory swim and, most recently, a sensory-friendly egg hunt. Miles for Madison is also working to build inclusive parks in the Chatfield Basin.

    The race will take place at Providence Park, located within the Sterling Ranch Community. The race address is 8100 Piney River Avenue, Littleton, CO 80125.

    Prizes will be awarded to the top 3 finishers in the 5 K, male and female.

    The Human Potential Running Series Presents

    The Indian Creek Trail Runs @ Indian Creek Campground

    The Indian Creek Trail Runs is the oldest official race of HPRS and is also known as our annual “Fall Classic.” This event features some of the best, seldom used, single track trails of the Denver Metro area. Participants will travel through the lower and upper montane ecosystems of the Front Range; from the lodgepole pine forest around 6,000-8,000′ sprinkled with sprawling aspen groves, down to the tall grasses and red rocks of the lower montane areas around 5,000′. This time of year is known for the changing colors across Colorado’s landscape. From golden quaking aspen, to the bright red hues of low lying scrub oak, and the amber waves of tall grasses of America’s high prairie.

    You’ll find it hard to believe that you’re so close to a major city, one that you can see from the many viewpoints along the route. While you admire glimpses of the city, you’ll also see the same red rock formations that make up the Red Rocks Amphitheater, and occasional glimpses of nearby 14ers that tower above the Colorado landscape.
