September 12, 2021, will mark the return of the Brookfield Zoo Run - with courses entirely within the world-renowned Brookfield Zoo!

Each year more species lose their race for survival and disappear from the wild. But it is a race we can win, and YOU CAN HELP! The Chicago Zoological Society Animal Care and Conservation Fund is dedicated to making a difference for these species across the globe and with each race entry, we will raise both awareness and funds for this great cause.

Run individually, with your friends or, better yet, team up and race against other family members, teammates, or classmates. It will be a race you will always remember and the most serious fun you'll ever have! Each participant will receive a sling backpack, a bib containing your timing chip as well as snacks and beverages! 

And that's not all...Bring your family and friends in FOR FREE to help cheer you on and enjoy the zoo.
