The course starts in downtown Tulsa and winds through residential neighbourhoods and the University of Tulsa campus, with local block parties along the way. It is USATF certified and counts as a Boston qualifier. Half marathoners share the route with the full field until around mile 11, then peel off to finish at Guthrie Green while marathoners carry on. A 5K runs the day before, and there are double options that combine a 5K with the half or the full.
