Whether you’re a runner, walker, hiker, cyclist, swimmer, or simply looking for a fun way to stay active, the Chastain Challenge is for everyone. From September 1 through October 15, participants will work toward completing 100 mileswhile supporting the Chastain Park Conservancy and helping keep Chastain Park clean, safe, and green.
One Challenge. Endless Ways to Participate.
The best part about the Chastain Challenge is that you can complete your miles however you choose. Walk your neighborhood, run your favorite trail, bike with friends, hike on the weekends, or even convert many of your workouts into miles using our Challenge app. Participate on your own schedule, at your own pace, from wherever you are.
Whether your goal is to improve your fitness, spend more time outdoors, or simply stay motivated alongside a supportive community, the Chastain Challenge is designed to help you get moving while making a difference.
New This Year
We’re excited to introduce our new Challenge app, making it easier than ever to track your progress, connect with fellow participants, and stay motivated throughout the six-week challenge. The app allows participants to log activities, convert eligible workouts into miles, view leaderboards, and celebrate milestones along the way.
More Than Just Miles
The Chastain Challenge is about more than reaching 100 miles. It’s about building community.
Throughout the Challenge, participants will be invited to join community walks, group runs, special meet-ups, and fun events that bring people together while enjoying one of Atlanta’s most beloved parks.
We’ll also kick everything off with our Kickoff Party on Saturday, August 30, where participants can pick up their Challenge gear, meet fellow challengers, and celebrate the start of an exciting six weeks.
Every Registration Gives Back
Every registration directly supports the Chastain Park Conservancy’s mission to preserve and enhance Chastain Park for the more than 3.2 million people who visit each year.
Your participation helps fund trail maintenance, landscaping, playground improvements, volunteer programs, environmental stewardship, and the ongoing care of Atlanta’s largest city park.
Join the Challenge
Whether you’re participating for fitness, fun, or to support Chastain Park, we’d love to have you join us.
Registration is now open, so gather your family, friends, coworkers, or neighbors and take on the Challenge together.
We can’t wait to see what our community accomplishes this year. Let’s make this our biggest Chastain Challenge yet!
