The Forge Trail Run Festival returns Saturday, Nov 14, 2026, with 10K, 20K/half marathon, 30K, and 60K trail races starting and finishing at The Forge: Lemont Quarries.
Trail runners get a late-fall goal on Saturday, Nov 14, when The Forge Trail Run Festival returns to The Forge: Lemont Quarries. The race day offers 10K, 20K/half marathon, 30K, and 60K distances over the quarry's natural terrain, with start and finish right at the adventure park. It is a scenic, challenging way to spend a November Saturday, and the shorter 10K keeps the day accessible to newer trail runners. Spectators can cheer from the park, then head into historic downtown Lemont for lunch. Register in advance on RunSignUp, since trail races cap their fields.
