The Colorado Marathon

Embark on an unforgettable running journey at The Colorado Marathon, set to take place on May 3, 2026, in scenic Fort Collins, CO. Offering a full marathon (26.2M), half marathon (13.1M), 10K, and 5K, this event is renowned for its predominantly downhill course and breathtaking scenery, earning it the reputation as "America's Most Scenic Course". Runners consistently praise the course for its beauty and its potential for personal bests, making it an ideal choice for those chasing a Boston Marathon qualifying time.

The marathon begins at an elevation over 6,000 feet, guiding participants on a steady descent along the picturesque Cache la Poudre River. This stunning route through the Poudre Canyon provides expansive views of the Rocky Mountains, lush green peaks, and ample shade, before gradually flattening out as it approaches Fort Collins. Aid stations are strategically placed throughout the course, including at miles 2.6, 5.0, 7.2, 10.1, 12.8, 15.3, and 16.8 for the marathon distance. Typical race day conditions in early May feature comfortable highs around 65F and lows around 39F, with a modest 11% chance of precipitation, creating a favorable environment for racing.

What truly sets The Colorado Marathon apart is its blend of challenging altitude with significant elevation loss, a combination that has historically resulted in a high percentage of Boston Qualifiers. The vibrant community atmosphere is palpable, especially as runners reach the lively finish line in Downtown Fort Collins, adjacent to Washington Park. Here, enthusiastic crowds, food trucks, and local craft beers await to celebrate every finisher's accomplishment. Beyond the race, participants can look forward to a quality Brooks tech shirt and a unique medal featuring the Colorado state flag and a built-in bottle opener.
