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.
