Crystal Bridges Endurance Grinduro

August 3, 2019 @ 8:00 am 5:00 pm

50 Mile grinder with 3 stages.

Crystal Bridges Endurance invites you to experience some of the best gravel in Western Arkansas and Eastern Oklahoma.  This challenge now in its second year starts in the beautiful downtown of Siloam Springs, AR. Racers will be led out of town and unleashed onto 50-60 miles of hard-packed, fast-rolling gravel backroads.  This route takes you over the Illinois River and several creeks, along scenic farms and historic buildings. The rolling hills give you plenty of time to warm up for the grueling but rewarding climbs that signify the last few miles of the race.

There will be a convenience store at the halfway stop with snacks for purchase, free water-refill station, and restrooms. Riders are expected to be self sufficient. This means you are responsible for carrying all your supplies you will need including water, food, tools, spare tubes, etc.  We will provide a limited amount of sag support but that does not preclude you from taking care of yourself out on the course. If you are not comfortable supporting yourself for 50+ miles, please consider shortening your ride distance and note our bail-out points.

The full race route will be released on July 28th.  Until then, follow Crystal Bridges Endurace on Instagram and Facebook to see “teaser pics” taken along the route.
