Rattler Trail Race 50K

2026

The Rattler Trail Race 50K takes place in April at Palmer Park in Colorado Springs, covering two loops of roughly 15.5 miles each with about 3,800 feet of total climbing. The technical singletrack winds through one of the city's most varied trail systems, where sandstone bluffs and distinctive rock formations create constant visual interest against a backdrop of Pikes Peak and sprawling city views. While the elevation numbers might look manageable on paper, the technical terrain demands attention throughout. Runners navigate narrow singletrack that weaves between rock outcroppings and along ridgelines, with the course's challenging footing often mattering more than the moderate climbing. The relatively high altitude (starting around 6,300 feet) and Colorado's unpredictable spring weather add variables worth considering for pacing and gear choices. This race suits runners who appreciate technical trail running and don't mind working for their views. The two-loop format means you'll get familiar with the terrain, but also face the same technical sections twice when legs are fresh and again when they're not. Runners looking for fast, flowing trails might find the constant rock navigation more demanding than expected, while those who enjoy problem-solving their way through varied terrain will feel right at home.
