KROP returns for Year 2 at Welling Ridge Trails near Tahlequah, Oklahoma (19679 S 550 Rd, Tahlequah, OK 74464). The event uses a 4-mile loop with the start/finish area as the lap hub. Each loop has about 417 feet of elevation gain and loss. The trail is described as single-track, rock-covered, and root-twisted. The event is organized as a 12-hour trail running event and takes place rain or shine; there are no refunds unless the event is changed for life threatening weather.
