Loop The Hooch 50K/25K/Team Relay

The Chastain Chase 5K Run and 3K Walk is a joyful community tradition held in celebration of National Cancer Survivors Day. Benefiting Cancer Support Community Atlanta, this family-friendly event invites participants of all ages to run or walk a beautiful course through historic Chastain Park. Participants are encouraged to create teams of friends, family members, and coworkers to walk or run together in honor of a loved one who has been affected by cancer. It’s a meaningful way to celebrate survivors, remember those we love, and come together as a community of support.

Families and strollers are welcome! Registration for Walk-Up participants opens at 7am and the 5K and 1.5 walk start at 8am sharp.

The Chastain Chase benefits Cancer Support Community Atlanta, a nonprofit organization affiliated with Northside Hospital Cancer Institute, dedicated to providing support services for people facing cancer. Funds raised will help provide support groups, stress reduction classes, nutrition programs and education forums to support people through a cancer diagnosis, treatment, and survivorship.

The 48th Annual Possum Trot 10K and Fun Run will have a virtual and in-person registration option. The in-person race is a Fun, Flat and FAST course along the banks of the Chattahoochee River! The race is an important Community event for CNC and the proceeds benefit environmental education programs focused on the Chattahoochee River and watershed. This 10K is also a Peachtree road race qualifier!

On August 8th, 2026, an anticipated 2,000 runners, walkers, and spectators, will gather for the 2026 Vinings Downhill 5K race. The Vinings Down Hill 5K course begins at the top of Mt. Wilkinson, winds around the Cumberland Mall area, and ends at the Lovett School (280-foot net drop).

Despite the name of the race, well, it’s “not quite” all downhill…there are 3 hills to climb throughout the race – at the half-mile mark, during the second mile and during the last half-mile. There are also 3 really amazing down hill sections that make up for those climbs!

There is also a Kids 1K Fun Run and a fun Doggie Dash & Costume Contest!

Our event includes a huge post race party at Vinings Jubilee with awards, music, great food and expo.
