The Illinois Half Marathon Calendar is a complete simplistic listing of Illinois Half Marathons. Currently the Illinois half marathon schedule has 2021 Illinois half marathons and 2022 Illinois half marathons as they roll in. Illinois half marathons 2021 & Illinois half marathons 2022 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.
