About This Race

The Sunrise Scramble serves as a strategic training ground for runners preparing for longer ultras, offering a unique opportunity to develop crucial night running skills in a supported environment. Set in Glendo, Wyoming, this time-based event challenges participants to complete as much distance as possible within their chosen time limit, from a manageable 3-hour option up to a full 24-hour endurance test. The race utilizes multiple loops of varying distances, allowing runners to customize their experience based on their goals and current fitness level. Starting before dawn at 6:03 AM, participants can practice headlamp navigation, test fueling strategies, and experience the mental challenges of running through the night. The format makes it particularly valuable for first-time ultra runners who want to experiment with gear and pacing without the pressure of covering a fixed distance. With space for up to 500 participants and a terrain that's entirely on paths, the Sunrise Scramble offers a controlled yet authentic ultra experience. The absence of traditional aid stations means runners must be self-sufficient, adding another layer of preparation for more remote ultra events later in the season.

The course consists of multiple loop options of varying distances, all contained within the path system around Glendo. Runners complete as many loops as they can within their chosen time limit, whether 3, 5, 10, or 24 hours. The entirely path-based terrain provides consistent footing without technical challenges, allowing participants to focus on their night running skills and pacing strategies.
