Schwendiman T3 50 is an exhilarating self-supported endurance adventure that takes runners through the scenic landscapes of eastern Idaho from Schwendiman Farm to the Rexburg North Temple and beyond. Participants have complete freedom over their start time, with options ranging from midnight to late evening on challenge day, allowing for a personalized experience. The route itself is not strictly defined; adventurers must reach all required checkpoints in order but are free to choose any path that connects them while adhering to public roads and permitted areas. The challenge incorporates NFC checkpoint stickers along the way, which runners use to check in through an online platform as they arrive at each designated location. These virtual check-ins can also unlock optional photo challenges for bonus points, adding a layer of excitement similar to a scavenger hunt. This event is designed to be low-cost and self-supported, encouraging participants to navigate independently while managing their own food, water, safety, and support needs. While there may be limited unmanned support or drop-off locations available, adventurers should come prepared with the necessary provisions for an independent journey through farmland and temple grounds. The public progress board provides real-time updates on adventurer status, checkpoint completion times, and points earned throughout the day, fostering a sense of community among participants. The challenge strictly prohibits the use of bikes, scooters, rides, or any form of motorized assistance, ensuring that runners complete their 50-mile journey underfoot alone. Schwendiman T3 50 offers an immersive experience through Idaho's picturesque countryside and historic landmarks, perfect for endurance enthusiasts seeking a unique adventure.
