Weather and safety information

Natives to Colorado are familiar with the day to day weather here. While the average low temperature in early October is 35 degrees and the average high is 65 degrees, please be prepared for anything. We hope to have the perfect weather on race day, but there’s always a possibility of rain or snow on the trail making for muddy conditions.

Don’t be surprised when running our open space trails. Expect to see rabbits, prairie dogs, deer, fox, coyote, birds, and other wildlife.

If you are traveling from lower elevations, be prepared for some shortness of breath. The high point of the course is 6,700 feet, roughly 1,500 feet higher than the mile high city of Denver.
