Scheduled for July 5th, 2025, this marathon offers a choice of multi-distance routes: 7km, 14km, 28km, 42km, and 56km, each embracing the unspoiled wilderness of pristine lakes and densely forested trails. The course is renowned for its rugged landscape—expect to navigate steep inclines, serpentine paths with rocky underfoot, creeks, and beaver dam crossings. It's a true testament to agility and endurance, demanding quick footwork in technical sections and providing stretches where speed is attainable.

Known for its rolling terrain, the Limberlost Challenge stands out within the Ontario Ultra Series for its technical difficulty, featuring continuous elevation changes and frequent encounters with roots and rocks, posing an exhilarating challenge even for veteran runners. Those partaking in the shorter 7km and 14km races will find them walker-friendly, offering a more leisurely yet equally breathtaking nature trek.

The event is efficiently supported with full aid stations placed strategically at 4.4km, 11.4km, and at the Start/Finish line, ensuring runners are well-nourished, with portable toilets available for convenience. With a runner cap of 700 participants, registration is a must ahead of the July 2nd, 2025 deadline, with race kits available for collection on the morning of the event.

The Limberlost Challenge is eco-conscious, operating as a cupless event and urging runners to bring their own drinking vessels. Commemorative t-shirts are available for early registrants, reflecting the event's commitment to sustainability by offering a no-shirt option with a donation made to local charities.

This exceptional trail marathon offers not just a race, but an experience—melding the kinetics of athletic prowess with the hypnotic allure of Ontario's wilderness.
