Please come volunteer with the Crohn's and Colitis Foundation's Chi-Town Half Marathon; they will be working an aid station. Sign-ups will close Monday, so please sign up ASAP! This event conflicts with the Bunny Rock 5K event, so if you are signed up for that, please do not sign up for this. However, if you're on the waiting list for the Bunny Rock event, you should totally sign up for this instead!
