307 Mud Racing is an organization that puts on side by side mud races and an occasional mud bog in Crook and Campbell County-Wyoming. 307 Mud Racing put on races in the spring and summer months at Rumble Ridge Speedway in Gillette, Wy. The track is located above the Gillette Thunder Speedway. Our goal is to put on a fun-filled family event that everybody can enjoy. We have participants come from surrounding states to participate in the races and we appreciate every one of them!
