Welcome to the inaugural Oklahoma Gravel Growler Ultra-Marathon!  To register, go to the Registration Page for our link to BikeReg.com.  For questions about the schedule of events, please visit the Schedule page.

We think you are going to enjoy the cool course we have laid out for you.  There will be 6-8 aid stations on the course.  Every station will be equipped with water, HEED, Hammer Gel, Endurolytes, first aid kit, chairs.  Depending on weather we may have tents at each as well (at least every second one will have some shelter, all will have volunteers and vehicles so if a runner is in need of more, we will have it available.  After the midpoint all aid stations will have the above plus flat cola, broth and some combination of real food (from crackers to potatoes to cookies to fruit).  If you don’t see something you need, let us know and we will do our best to get it before race day!

Our Ultra sponsor Orange Mud has supplied us with a pair of Gear Vest 2L running vests for the male and female winners!

Every runner gets a unique, custom finishers medal!

Every runner gets their own unique registration swag back and a long sleeved event shirt!  You won’t regret signing up!
