21km COURSE DESCRIPTION: The 21km follows the 10km course which starts from the Wild Iris Climbers’ Main Parking Lot just off of Limestone Mountain Road. The course immediately climbs north on FR327 past the radio towers and then takes a steady rolling descent. This descent is beautifully framed by the Wind River Mountains to the west and Red Canyon to the east. The first of two aid stations will be at mile 1.5 (this is the 5k turnaround); this aid station will also be stocked for the return. The second aid station will be at the 10km turnaround. From the 10km turnaround, you will continue onto a technical and “elevation intensive” 11k loop (includes one aid station at the furthest point on the course). From here, runners rejoin the 10k course for the 1000′ climb back up to the finish. This is an exceedingly hard and rewarding race. It is not for the weak of heart or legs.
