The Forge Trail Run Festival
Lemont, United States • 15 Nov 2025
The Forge Trail Run Festival, held in Lemont, Illinois, offers a challenging late-fall trail running experience with distances of 10K, 20K (half marathon), 30K, and 60K. The courses start and finish at The Forge and wind through single and double-track trails in the woods, gravel paths, and around the historic Lemont Quarries and I&M Canal. The terrain varies from flat gravel to technical single-track with dirt, rocks, roots, and short steep inclines, making it moderately challenging for experienced trail runners. The 10K is one lap, the 20K two laps, the 30K three laps, and the 60K six laps. Aid stations are available for longer distances, and trail running shoes are recommended.
