2027 Think Spring De Pere Half Marathon | 5K Run/Walk

The Think Spring De Pere Half Marathon starts and finishes at De Pere Middle School, sending runners through countryside and along the Fox River Trail, past St. Norbert Abbey. The certified course is flat and fast, with a net drop of just 0.05 m/km, making it a prime spot for a personal best. The race has a small but loyal following, with about 27% of the roughly 217 finishers returning in later years. Runners come from around five states, drawn by the fast course and the post-race party at Greystone Ale House, where half marathoners get a complimentary drink. The 5K follows a shorter loop, and all participants receive medals, free professional photos, and access to a huge post-race food buffet. With indoor space before and after, and a waved start, it's a well-organized event that caters to both serious runners and first-timers. The weather is typically cool, with temperatures ranging from 35–52°F, ideal for running.
