Since the launch of #SheddTheStraw last spring, businesses across Chicago have taken steps to eliminate their use of single-use plastic straws. Now, one of Chicago’s biggest events is getting involved.

This week's primary isn't the only race in town. Amateur runners can apply for a spot in the 39th annual Chicago Marathon starting at 10 a.m. Tuesday.
