Desert RATS: Stage 4 Map

Presented by Gemini Adventures, the Desert RATS Kokopelli 150 is possibly the most epic adventure race in the west. As the longest-running stage race in North America, this week-long adventure is designed to test both mental and physical limits of even the most seasoned athletes.


Stage 4 is by far the most challenging stage of the race. With a stout 7,800' of climbing spread across 41 miles, Gemini Adventures proclaims that "this stage is what the race is all about." The course is full of beautiful red rock formations and also offers expansive views of the La Sal Mountains to the South. With an ending elevation near 6,500', finishers of stage 4 are rewarded with a quiet night sleep under the vibrant star-filled sky.

Starting at the Colorado River, racers start with an arduous 5-mile climb to the Top of the World Aid Station. Ahead, runners begin the traverse through what is undoubtedly the most remote part of the entire course. With 12+ mile legs between the next two aid stations, nutrition and hydration must be planned carefully.

Runners depart between 8 and 9am with a generous course cutoff time of midnight. With the potential to be on the trail after sunset, there are additional gear requirements for stage. To ensure runner's safety, gear is also checked at the start of the day and at each aid station along the way. Getting caught after dark without a light could prove extremely dangerous in these remote canyonlands.

Per the official race guide for 2019, aid stations are available in the following intervals.

5.5mi – Top of the World Aid Station 17.8mi – Onion Creek Aid Station 30.2mi – Beaver Mesa Aid Station 33.7mi – Gateway Aid Station 41.4mi – Rock Castle (Stage 4 Finish)
