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 with open timing (No official start time to eliminate an assembly of a group. Runners and walkers will start when they are able to practice social distancing) 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
