City of Rocks Ultra @ Lynn Road, Almo, ID, United States on 03 June 2023

Distances: Marathon (27 miles), Extra (32.3 miles), and Ultra (51.6 miles)
Join a bunch of other crazy endurance athletes (2 and 4-legged) in City of Rocks National Reserve on Saturday, June 3rd. Come enjoy the chance to run a fully supported loop through City of Rocks National Reserve and Castle Rocks State Park. Test your mettle on courses that climb through the most beautiful terrain in southern Idaho. This is a no-frills event that is run in conjunction with an equine endurance ride. Distance changes are welcome before AND during the race. The trail will take you past beautiful granite faces and through ancient Shoshone and Bannock tribal hunting grounds. You’ll run a portion of the historic California Trail and see the names of emigrants from the 1800s scrawled in axle grease on Camp Rock. The Ultra course includes a loop through Castle Rocks, a cluster of stunning rock formations that date back 2.5 million years. The trail travels through pinyon pine forest and high-desert sage brush but is primarily in direct sun with little shade. Be prepared!
Don’t let the name City of Rocks fool you. Most of our trails are crushed granite dust or sand. You will encounter portions of trail with some rock but for the most part the footing is great. Our trails are a mixture of single-track, double-track jeep trails, cow paths, groomed trails, and packed dirt road.
