The Hartley Park 10K course is celebrated for its fantastic terrain, primarily utilizing the region's well-maintained, packed fat bike trails. With approximately 95% of the route on unpaved surfaces, runners can expect a moderately hilly challenge that winds through serene woods, past tranquil ponds, and delivers scenic winter vistas. Typical race day conditions see invigorating highs around 20°F and lows near 2°F, with a minimal 3% chance of precipitation, creating an ideal crisp winter running environment. However, participants should be prepared for various snowy, icy, or cold conditions that can add to the adventure.

What truly sets the Hartley Park 10K apart is its immersion into the unique joys of winter trail running. Locals often claim that these snow-packed fat bike trails are even more enjoyable to run in the winter than during snow-free months. As part of the challenging Duluth Winter Trailrunning Series, finishing this race also brings you closer to earning the coveted "Winter Trail Series Survivor" award, presented to those who complete all four series events. Whether you opt for the trail running division or the snowshoe division, the Hartley Park 10K promises a memorable and exhilarating journey through the heart of Duluth's winter wilderness.
