Chicago, Illinois (United States of America) - "Run for the Zoo". For more than four decades, runners of all levels and abilities have been raising money to support Lincoln Park Zoo with Run for the Zoo, now in its 48th year. Taking place on May 31, 2026, this race is suitable for all experience levels and features a flat, scenic course that winds in and around the zoo, allowing for beautiful views of Chicago’s skyline, Lake Michigan, protected natural areas, and zoo habitats. Choose from: 10K run, 5K run, 5K walk, kids’ course (for kids ages 3-8), Wildlife Warrior (run both the 10K and 5K), and virtual race options.

More than 80% of that operating cost is funded by memberships, donations, guest visits, and events like Run for the Zoo.
