Intermediate Course: the opening swim is a wave-start .75 mile open water swim in Lake Decatur. Water temperature is typically in the low- to mid-70's for the race, posted daily on the website during race week. Swim start is in the water, approximately waist-deep, exit between two boat docks with volunteers on hand to assist water exit. The swim is a U-shaped point-to-point well defined by buoys and anchored boats. The bike ride begins at the mount line to the left of the TA exit and is a 19-mile out-and-back on closed roads through rolling hills in town and out to the turn-around on Il State Highway 105. Safety and support are very evident with police and volunteers along the entire course, first aid and water stations are scattered along the way. The bike dismount is on a long downhill with volunteers stationed to alert riders of the dismount line. The run for the Intermediate Course leaves the TA running to the athlete's right and following the lake to a turn around, then back on the lake front passing the TA and along the lake front, leaving the park running under US 36 and along Lake Shore Drive to the turn-around. Then back to the finish line in Nelson Park. Safety support and water stations are located just outside the TA, at the first turn, just beyond the US 36 underpass and at the final turn-around.

Turn left at the TA exit to the mount line and you're on your way!
