Join 3 Disciplines on this challenging course which has developed over eight years. It now features a time trial swim start, straight out and back rectangle course, an entirely closed challenging bike course (rolling to hilly the entire route) with a three mile straight to the back of the park. You will complete three loops. The run course is one of 3 Disciplines top three favorite courses. It will take you on a challenging trail run around the campground and some small ponds before participants come out just past the modern campground entry point. Then it is one mile back down to the finish line.
