50K COURSE DESCRIPTION

***IMPORTANT***

As of 2025, there is a minor course update. We no longer will be using the out & back section, and will instead be looping partial Lusardi at mile 18.5. Runners will go into the aid station, turn around and head down Lusardi for 1.5 miles before making a right turn to head back up. 50k Runners will now pass through Black Mountain Ranch Aid Station three times. Runners MUST CHECK IN to this aid station each time!

All race distances start and finish at Hilltop Community Park. Runners begin by climbing to the top of Little Black Loop trail and running through the beautiful single-track trails within the Black Mountain Open Space. 50K runners will then descend down the technical Miner’s Loop trail and wind their way down the Ahwee trail, until reaching Black Mountain Ranch Park (drop bags/3 passes). So far almost the entire race is winding single track with great views of surrounding mountains.

50K runners continue and complete the rolling Lusardi Loop trail, a mix of jeep trail and single track. Hidden, fun, and fast, the single track trail through Lilac Canyon will lead runners up Miners Ridge for an opportunity to master their second descent down Miner’s Loop trail. Terminating at the historical Glider Port staging area, runners will then head off on fresh trail to begin the climb to the Summit! After refueling and checking out the spectacular 360-degree mountain views at the Summit, runners dart mostly downhill to the finish, where food, drinks, and friends await you!

Well stocked aid stations and our experienced and motivating volunteers will help you along the way as you traverse and climb 5700 ft over the course of the race.
