The Forge Trail Run Festival

The Forge Trail Run Festival takes place at The Forge: Lemont Quarries in Lemont, Illinois, a late‑fall Midwest trail event set among woods, gravel paths, and the historic Lemont Quarries and I&M Canal. Runners may choose from 10K, 20K (Half Marathon), 30K, or 60K distances. All races share a common start/finish within The Forge, using single- and double‑track trails.

The 10K is one lap, the 20K two laps, the 30K three laps, and the 60K six laps, with terrain that ranges from flat gravel to technical dirt, roots, mud, and rocks. Trail shoes are recommended; finishers receive a tote bag, and 60K has a special finishers award alongside casual swag like a hat. Aid stations are provided for longer events, so participants should carry some hydration. Visit the organization's website for the most recent information.
