2021 marks the 28th anniversary of the Capital City River Run—a compilation of family-friendly races that celebrate, build awareness of, and financially support Greater Lansing organizations that promote education, the desire to learn, and healthy lifestyles. This run series provides a premier racing experience, highlighting both the eclectic urban corridor and natural beauty of Michigan’s capital city and adjoining rivers. 

The Capital City River Run makes a real impact within the community, benefiting Impression 5 Science Center and its mission to provide children and families access to science exploration through hands-on exhibits and participatory programming. 

Annual races include a Half Marathon, 5K Walk/Run, and the Sohn’s Kid’s Race. All race participants receive a long-sleeve pullover and finishers medal. The event is available as a virtual event, or in-person. The race will be chip timed by the Michigan Running Foundation and you can check your results during the race and on the web at

The half marathon and 5K races will start at Impression 5 Science Center on Sunday, September 19 at 8AM. The race can be completed virtually over the race weekend and participants can self submit results. Please know virtual results will not count toward age group awards. The Sohn's kids events will continue to stay virtual. The races will utilize the Lansing River Trail and finish at Rotary Park. Due to the capacity of the trail, the event is limited to 1,100 participants.
