About the race

Muddy Shamrock @ The Forge is a trail running event held at The Forge: Lemont Quarries in Lemont, Illinois. The race offers two distances: Trail Half Marathon (about 13.1 miles, run as two laps) and Trail Quarter Marathon (about 6.6 miles, one lap) on wooded single- and double-track trails around the historic quarries. Runners navigate dirt, mud, roots, rocks, and occasional technical sections along gravel and forest trails, with a common start/finish line and scenic quarry scenery.

Entry includes chip-timed results with live splits, awards, a Muddy Shamrock T‑Shirt, and a post-race party with food, beer, and music. Packet pickup occurs in Naperville and Lemont prior to race day. Visit the organization's website for the most recent information.
