Race starts and finishes at McAllister Park’s Optimist Pavilion #3 next to the playground in the center of the park. You can find parking near the pavilion or a short walk away. There are restrooms near the pavilion, and port-a-potties with hand sanitizing stations close to the start/finish line.
There are three water stations on the 50K/15K looped course, and one on the 5K course, that will be exclusively stocked with Crazy Water and Gatorade. Look for HydraPak signage that reminds you to pull out your collapsible cup! THIS IS A CUPLESS RACE--You must carry your own hydration device or a collapsible cup to fill at stations. We will have volunteers available to assist you. We will not have any paper cups. Please give a hoot and don’t pollute the trails, please dispose of your trash at Aid Stations or carry with you.
The course at McAllister Park is mostly flat and fast single-track trails. We’ll run on the Blue Loop, Mud Creek Loop, and Mosquito Lake trails through rocks, tree roots, dry creek beds, and lots of prickly pear cactus. All races start and finish at the same location.
