From the Organizer
Woods, dirt, mud, roots, and maybe some other adventurous trail stuff will be experienced at the 6th annual Muddy Shamrock Trail Races @ The Forge. And now that we've earned the 4th leaf in our clover, the race is now named the MUDDY SHAMROCK!
This early-season trail race will be run on wooded single & double-track trails with awesome scenery around the historic Lemont Quarries. Both races will traverse the single-track MTB trails within the woods and some gravel trails throughout the Forge and adjoining trail systems.
