The Forge Trail Half Marathon and Quarter Marathon (now known as the Muddy Shamrock) takes place in in Lemont, IL. Both the Half Marathon and Quarter Marathon traverse the woods, dirt, mud, and roots along mostly flat gravel trails of Lemont Quarries in the Forge and its adjoining trail systems. A few spots are technical with several short but steep inclines and downhills. The course will have a common start / finish line. Runners will complete 2 laps for the Half Marathon and 1 lap for the Quarter. There will be one aid station with water and sports drink located at the beginning of the second lap for the half. It is recommended to carry your own hydration and fuel.

Race Information
Woods, dirt, mud, roots, and maybe some other adventurous trail stuff will be experienced at the 4th annual Trail Half Marathon and Quarter Marathon @ 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-and 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. Race Information
As an early season event held in March we anticipate variable weather, creating more adventure to the race (or, gorgeous sunshine like in 2024!). Athletes will experience a unique trail race with a cool course, awesome scenery and a great venue based at The Forge: Lemont Quarries.
Course Information
The course traverses the single and double track MTB trails within the woods and some gravel trails throughout the Forge and adjoining trail systems. The course will have a common start / finish line. Runners will complete 2 laps for the Half Marathon and 1 lap for the Quarter. Total mileage will be approximately 13.3 +/- miles for the Half Marathon and approximately 6.6 +/- miles for the Quarter Marathon, but it is a trail and we don’t want to do anything funky to make it a perfect distance.
The gravel is mostly flat. The MTB and single/double-track sections have variable terrain and surfaces ranging from dirt, grass, rocks, mud, more rocks, roots, stumps, Sasquatch, etc. A few spots are technical with several short but steep inclines and downhills.
Trail running shoes are recommended.
Aid / Hydration Station: There will be one aid station with water and sports drink located at the beginning of the second lap for the half. Please plan on carrying your own hydration and fuel. We aim to go cupless for the 2025 event.
