Prepare for an unforgettable running experience at the Colorado Marathon on May 3, 2026, in scenic Fort Collins, CO. This event, celebrating over 18 years, offers a full marathon (26.2M), half marathon (13.1M), 10K, and 5K, catering to runners of all aspirations. Typical race day conditions in early May feature comfortable highs around 65°F and lows around 39°F, with a low 11% chance of precipitation, creating ideal running weather.

The Colorado Marathon is renowned for its stunning, predominantly downhill course, making it a favorite for those chasing a personal record or a Boston Marathon qualifying time. The full marathon begins at over 6,000 feet in Stevens Gulch, descending more than 1,200 feet through the breathtaking Cache la Poudre Canyon. Runners are treated to spectacular views of the Rocky Mountains and the nationally designated "Wild and Scenic River" as they follow the Poudre River. While the early miles offer serene canyon solitude, the course flattens out through the charming natural areas of Fort Collins before finishing in the vibrant Old Town. The race maintains 12 well-stocked aid stations approximately every two miles, offering water, Gatorade, basic first-aid, and portable toilets, with Honey Stinger gels and chews at select locations to keep you fueled.

Participants consistently praise the race for its exceptional organization and beautiful scenery. While the high altitude start may challenge some, the net downhill profile significantly aids speed. Many runners appreciate the ample space on the course, especially in the canyon, ensuring a smooth flow. The finish line for all distances is located in Downtown Fort Collins on Howes St., adjacent to Washington Park, where a lively post-race celebration awaits with music, food trucks, and local craft beer, often at Odell Brewing Co. The Colorado Marathon promises a rewarding and picturesque journey through the heart of Northern Colorado.
