The event is an ultra endurance triathlon offering multiple continuous distance options, including 1.5x or more full distance triathlon and half distance events. Registration closes on September 6 at 11:59 PM CT.
The course uses short, repeatable loops inside and just outside Ottawa Lake State Park to maintain athlete safety and frequent support. An on course Aid Station and Athlete Village provide access to a personal crew every loop for refueling, gear swaps, and assistance. Organizers coordinate with local state parks and townships and provide volunteers, real food options, and a 24 hour on site medical team. Event services also include guidance on nutrition and hydration preparation, training plans, sponsor discounts, and community calls. Visit the organization's website for the most recent information.
