Illinois Half Marathons
Illinois half marathons 2025
The Illinois Half Marathon Calendar is a complete simplistic listing of Illinois Half Marathons. Currently the Illinois half marathon schedule has 2024 Illinois half marathons and 2025 Illinois half marathons as they roll in. Illinois half marathons 2024 & Illinois half marathons 2025 also identify trail half marathons and walker friendly half marathons by a (T) symbol and a (W) symbol. The (T) means it is a TRUE trail half marathon 21k (off road, switchbacks, etc) and a (W) means it is truly "official walker friendly" requiring the half marathon to allow a minimum of 18:32 mile pace, minimum 4 hours for participants to finish the 13.1 mile distance.
The Illinois half marathon schedule of course features races such as the Chicago Half Marathon, Biggest Loser Run/Walk Chicago, and Rock'n'roll Chicago half marathon, and also a complete listing of Chicago half marathons, Rockford half marathons, Quad Cities half marathons, Schaumburg half marathons, Southern Illinois half marathons, Northern Illinois half marathons, and many more 1/2 marathons in Illinois.
