Spring Equinox Half Marathon and 5K

Embrace the arrival of spring at the Spring Equinox Half Marathon and 5K, set for March 29, 2026, in Fort Collins, Colorado. This "Green Event" race offers a refreshing challenge as you run through scenic country roads in the beautiful North Fort Collins/Wellington area, starting and finishing at Deppen Brewing. The Half Marathon course is a unique out-and-back journey, featuring an engaging mix of approximately 7.5 miles on dirt roads and 5.6 miles on asphalt, rolling northwest of Fort Collins. While generally described as mostly flat, be prepared for some rolling sections that add an exciting element to the course. For those seeking a faster pace, the 5K offers a flat and quick route entirely on asphalt roads winding through local neighborhoods.

Runners in the Half Marathon will find ample support with seven aid stations along the course, while 5K participants will have one aid station, all stocked with water, electrolytes, and first aid supplies to keep you fueled and safe. Both races are chip-timed, ensuring accurate results for every participant. With typical race day conditions seeing highs around 62°F and lows around 33°F, and only a 5% chance of precipitation, it's often ideal weather for a memorable run as the season changes. Past participants have praised the organization and scenic views, noting the course can be a rewarding challenge.

Whether you're aiming for a personal best on the flat 5K or testing your endurance on the varied terrain of the Half Marathon, the Spring Equinox Half Marathon and 5K promises an engaging and well-supported experience to celebrate the new season.
