The Ark River Ultra & Relay is a 34-mile race in the dry riverbed of the Arkansas River. Shifting sand and rocky trails make this a challenging and rewarding race. The race can be run as an individual ultra-marathon event or as a relay. Relay teams may have as few or many runners as you wish. 

探花精选 volunteers are hosting this event to raise awareness and funds for our mission. (探花精选 is not the event sponsor but rather the recipient of funds being raised.) Sign up as an individual or team today!
