Thank you to all who participated in the 2023 Champion of Trees 10K! It was a great day for 1,000 runners and walkers, who enjoyed one of Chicago’s most picturesque 10K courses on a beautiful spring morning. Participants ran or walked through a unique course with rolling terrain along the Arboretum’s East Side, gliding past trees from around the world and beautiful spring blooms. Racers can access their results here.
