2025 will be the 12th Annual IFTR!
The Iron Furnace Trail Runs take place at the beautiful Lake Hope State Park and Zaleski State Forest. 13.1 mile runners meander along single-track trails taking in the beautiful views and traversing into the rugged and remote Zaleski State Forest. Along the way runners will be treated with deep gorges, scenic overviews, and rocky outcroppings, and complete what many consider the hardest half marathon in Ohio. 4.5 mile runners will complete a more tame course and run along the shores of Lake Hope. Whatever distance you choose, you’ll be sure to run on a great course and have a memorable experience at the Iron Furnace!​
Permits:

This event is held in accordance with special use permits from the Ohio Department of Natural Resources for Lake Hope State Park and Zaleski State Forest. Please be considerate of the land and other users to ensure the future of the Iron Furnace Trail Run.

The 13.1 mile course will be marked with pink flagging along with direction arrows at key turns and intersections. 13.1 mile and 4.5 mile runners start at the same time and will run together for about 1 mile before the split-off. **DON’T ACCIDENTALLY GO ON THE WRONG COURSE AT THIS POINT!** Follow your flagging color. The 13.1 mile course is the more challenging of the two courses with frequent steep uphill and downhill sections. Most of the course is run on the rugged Backpack Trail of Zaleski State Forest. This course can be described as difficult and hilly but totally worth the challenge! Runners will be greeted with several spectacular vistas as well as one of the most gorgeous trail sections in SE Ohio featuring rock outcroppings and gorges that might just make you stop running to enjoy the sights. Make sure you save just enough energy for the last 1/2 mile uphill on the Greenbrier Trail before returning to the finish at the lodge. Shortly after entering onto the Backpack Trail and again just before exiting the Backpack Trail, make sure you look across Route 278 to see the Hope Furnace in which the race was named after! Cut-off information: the course remains open for 4.5 hours (20:36 pace per mile) There will be a cut-off at the mile 8.3 mile aid station of 3 hours (21:41 pace per mile) Runners that do not reach the 8.3 mile aid station in 3 hours will be transported back to the finish line. 13.1 Mile Terrain Overview ● 2219 feet of elevation gain ● 9.9 miles of singletrack trail ● 2.2 miles of gravel road ● 1 mile of pavement 13.1 Mile Turn-by-Turn Directions ● The 13.1 mile course starts in the parking lot at Lake Hope State Park Lodge. ● Runners will run down the paved Lodge Road through the campgrounds for approximately 1/2 a mile. ● Veer off the road to the left onto the Greenbrier Trail and decent 1/2 mile.● Turn right at the split-off and cross a wooden bridge.
