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.
