The Bellin Run, a prominent annual running event in Green Bay, Wisconsin, is set to celebrate its 50th anniversary on June 13, 2026. Initially intended as a one-time event in 1977 to fund a new cardio unit, it has evolved into a major community gathering, attracting thousands of participants each year. The inaugural race saw 881 runners, while participation peaked at 20,000 in 2013. George Kerwin, the founder and original race director, reflects on the event's growth and his own journey from a hospital housekeeping role to becoming the President of Bellin Health. Kerwin remains an advocate for cardiovascular health and fitness, continuing to support the run despite his retirement in 2018. Notably, Olympic Marathoner Frank Shorter, who won the first race with a time of 30:32, will return to participate in the milestone event. The success of the Bellin Run is attributed to the dedication of volunteers and the local running community, ensuring its place as a beloved summer tradition in Brown County.
