Ironstone 100K Ultra

Join the ultimate challenge at the Ironstone 100K Ultra, a savage point-to-point ultramarathon on the wildest trails of Pennsylvania's Ridge and Valley region. Starting at Canoe Creek State Park and finishing at Greenwood Furnace State Park, this 100-kilometer race will test your endurance with unforgiving technical terrain, ridge running atop Tussey Mountain, and unique features like old-growth pines and craggy ledges. With a finish time limit of 23 hours, participants must have prior trail running experience, having completed a 50K trail race to qualify. Apart from the physical challenge, entrants are required to contribute at least 8 hours of volunteer work or make a donation to support the trails.
