SWIM Course

Swim is mass start at Stockade Lake in Custer State Park. Everyone starts out in knee deep water. 2 laps counter clockwise for Half. 1 lap counter clockwise for Olympic distance. 


2 Laps for Half Distance

1 Lap for Olympic Distance

Lap 1

Leaving the transition, turn right onto US-16 heading east 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 and then turn right heading north onto Iron Mountain Road. Head north until making it to South Playhouse Road. Onto South Playhouse Road head west continuing until you meet up with US-16 again.

Lap 2

On the second loop instead of heading east on US-16 you will head west back to the Lake and transition area before heading east again. At all road crossings or turnarounds there will be volunteers directing you. So 
  don’t worry about getting lost.


Run Overview

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 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
