Ironstone 100K 2026: A Weekend to Remember

The second Saturday in July once again brought runners to The Ridge and Valley region of Pennsylvania to test themselves against 63 miles of Pennsylvania's most unforgiving terrain. This year's Ironstone 100K proved to be our biggest—and arguably our strongest—event to date.

A record 113 runners registered, with 105 ultimately toeing the starting line, making this the largest field in race history. More importantly, those runners arrived prepared for what Ironstone demands.

When the final finisher crossed the finish at Greenwood Furnace State Park, Ironstone had recorded its highest finish rate ever: 73.33%. On a course that has earned a reputation for demanding equal parts strength, patience, and stubborn resolve, that achievement speaks volumes about this year's field.

Several factors contributed to the historic results. Favorable weather throughout much of the event provided runners with conditions that allowed them to perform at their best. Just as importantly, this year's field was the most experienced Ironstone has ever welcomed. Many participants returned after previous finishes or DNFs with a deeper understanding of the course, wiser pacing strategies, and a healthy respect for what awaited them. Experience, preparation, and good conditions combined to produce one of the strongest overall performances in race history.

The front of the race reflected that strength.

Twelve runners finished in under 16 hours, a remarkable number considering the previous four editions of Ironstone had produced only ten sub-16-hour finishes combined. The depth of talent was evident from the opening miles and continued throughout the day and into the night.

History was also rewritten in the record books. Both the men's and women's course records fell, with the women's record being lowered by a remarkable margin that reset expectations for what is possible on this demanding course.

Perhaps even more meaningful than the statistics were the stories. Many returning runners arrived carrying unfinished business from previous years. Some came back to improve upon earlier performances. Others returned after experiencing the disappointment of a DNF, determined to write a different ending. Watching those runners persevere and ultimately cross beneath the finish line arch was one of the most rewarding moments of the weekend.

Another encouraging outcome was what didn't happen. Despite 105 runners spending hours traversing rocky ridges, remote forests, and technical trails, the event concluded without any serious emergencies requiring medical or search-and-rescue response. While sore legs, scraped knees, and a few colorful words directed at Pennsylvania rocks were plentiful, every runner ultimately made it safely off the course which is a testament to thoughtful preparation by the runners, the vigilance of our volunteers, and the professionalism of our medical and communications teams.

Ironstone has always been about more than times and placings. It is about the willingness to step into uncertainty, to embrace difficult miles, and to discover something about yourself somewhere between the rocks, ridges, forests, and long stretches of solitude that define this course.

To every volunteer who gave their time, every crew member who kept runners moving, every spectator who rang a cowbell, and every runner who stood on the starting line... thank you for making another chapter of Ironstone possible!

Whether you found something truly magnificent out there or something completely unhinged, we are grateful you chose to spend your weekend with us.

Until next year, happy trails.
