Embark on an unforgettable trail running adventure at the Iron Furnace Trail Run on April 4, 2026, in McArthur, Ohio. This highly anticipated event, celebrating its 13th annual running, is renowned for its challenging yet rewarding courses through the picturesque Lake Hope State Park and the rugged Zaleski State Forest. Runners can choose between a formidable 13.1-mile half marathon or a scenic 5-mile race, both offering a true test of grit and a memorable experience.

The 13.1-mile course, often regarded as one of Ohio's hardest half marathons, plunges runners into the remote beauty of Zaleski State Forest. It boasts a true distance of 13.49 miles and a significant 2185 feet of elevation gain, with over 12 miles of technical singletrack trail winding through deep gorges, past stunning rocky outcroppings, and offering breathtaking scenic overviews. The 5-mile course, a completely redesigned route as of 2025, features 5.11 miles with 587 feet of elevation gain, running almost entirely on singletrack trails around Lake Hope and including a major climb followed by a downhill finish. Typical race day conditions in early April feature highs around 62F and lows around 36F, with a modest 16% chance of precipitation.

Both races start and finish at the Lake Hope State Park Beach parking lot, a new location since 2025 designed for a more dedicated race experience and improved parking, eliminating the need for shuttles. Aid stations are strategically placed on the 13.1-mile course at miles 2.93 and 8.05, and at mile 3.1 for the 5-mile race. The Iron Furnace Trail Run prides itself on its strong community atmosphere, drawing runners back year after year to conquer its demanding trails and immerse themselves in the camaraderie of fellow enthusiasts.
