Tulsa Urban Adventure

First held in 2015, the Tulsa Urban Adventure sends 100-mile runners through four 25-mile loops of Tulsa streets, starting and finishing at RunnersWorld Tulsa. The terrain is flat urban pavement; QuikTrip convenience stores serve as aid stations roughly every 2–3 miles, with one staffed station at base. The course is unmarked — runners navigate by printed turn-by-turn directions and a provided map, with pacers recommended after the first loop. The 34-hour cutoff governs all distances. Temperatures can push into the 90s during the late-September race.
