The swim is a mass start at Stockade Lake in Custer State Park for the Olympic and 70.3 distances. Everyone starts out in knee deep water. 2 laps counter clockwise for the 70.3. 1 lap counter clockwise for the Olympic distance. Yes, the Olympic distance is longer than the "normal" Olympic.



Elevation Gain:
70.3 = 5118

Olympic = 1 lap
70.3 = 2 laps

Leaving the transition, turn left on stockade lake drive and then turn right onto US-16 heading east and go about 12 miles to the park gate. Exit the park still heading east and go about a mile where the turnaround will be. Head back to the gate but before the gate turn right heading north onto Iron Mountain Road. Head north until making it to South Playhouse Road. Take a left  onto South Playhouse Road and head west until you cross the wooden bridge. Cross the bridge and take a left on highway 87.  Continue on 87 until you meet up with US-16 again.  At the intersection of 87 and US-16 you will take a left for lap 2(east) OR if you are Olympic you'll take a right(west) and head back to transition.

70.3 & Oly

For the run you will leave transition going south on the gravel road until you hit Stockade Lake Drive.  You will take a right and follow this road until you come to the first aid station and the intersection of Highway 16A. This is where the first aid station will be. You will take a right on the bike path and head towards the stone bathroom. Turn around there and then take the bike path towards Custer. You will go about 1.5 miles towards Custer and there will be an aid station along the way and the turn around after that. You turn around here and when you get back to the first aid station you will turn right onto Lower French Creek Road and head back to transition the way you came. If you're doing the Olympic you're done, if you're doing the 70.3 your 2nd lap turn around is near transition and the finish




For the Sprint bike, you will leave transition and take a right onto stockade lake drive.  You will go all the way until it T's off on 16A, taking a right here and going until you get to stockade lake drive. You will then pass the transition area, doing 2 more laps around the lake for a total of 10.05 miles.





For the sprint run, you will leave transition heading south on the gravel road. Once you hit pavement you will turn right and head to the turn around and go back to the transition area for the turn around for a total of 3 times for a 5k. This is a very spectator friendly run
