We are pleased to announce the Annual Half Madness 13.1 Half Marathon and 10K held on Sunday, September. The race starts and finishes in historical and scenic Batavia Ill. Targeted to be a warm up race to Chicago, Milwaukee and Twin Cities Marathons. Established in response to an increasing demand from hard-core runners and amateurs looking to get their feet wet before the main event and runners in between who want a serious challenge, but don't have the time to train for a full marathon.

A well organized event hosted by Multisport Madness. The course starts/ends in downtown Batavia on the banks of the Fox River. There are hills that challenge the course around the river but for the most part, it is relatively flat. Parts of the course are along the Fox River which adds to the scenery. Great post race festivities. Due to the success of this race in '09, MSM added the 10K.
