The Math Walking Club began as a rivalry between Koch and DeBacker. In spring 2021 as vaccinations became widely available, they reached out to students who had been living alone in Ann Arbor for over a year. They continue to walk six times a week during this semester. They meet weekdays during the walking club's 6:05 am walk and every Sunday at either the 6:30am or 8:30 am walk. Walks are four to five miles long, wear apropriate foot wear. For details about where to meet, please visit walking club's discord server:
