About the Event

The Sloth Run 5K/10K/13.1 ATLANTA returns to Decatur, Georgia on August 29, 2026.
Located in the heart of Decatur, this event takes place at Druid Hills High School, a vibrant community hub surrounded by lush greenery and historic charm. Race morning finds participants gathering amidst the cool air of early autumn, with temperatures ranging from 23 to 33 degrees Celsius, creating an ideal setting for runners. The atmosphere is relaxed and inviting, perfect for both seasoned athletes and newcomers alike.
For its sixth year running, this event continues to grow in popularity while maintaining a small-group feel that keeps the vibe casual yet supportive. With over 100 participants expected each year, it's clear why locals look forward to it as a highlight of their community calendar. The Sloth Run aims not just to race but also to foster connections among runners through its local club invitations and digital training packs.
Course and conditions span three distances: the classic 5K (five kilometers), the longer 10K, and the half-marathon (21 kilometers). All participants share a common goal of enjoying their pace without the pressure typical in more competitive races. The course meanders through scenic streets lined with trees before looping back to Druid Hills High School.
Participants start at 7:30 AM for Wave A, followed by Waves B and C starting at 8:00 AM and 8:30 AM respectively. Those who sign up late can join upon arrival; coordinators remain on site until the final wave finishes three hours later. The course itself presents a flat terrain with minimal elevation changes, ensuring an easygoing experience for all.
Aid stations are strategically placed along the route to provide water and support as needed. On race day, expect temperatures around 28 degrees Celsius, which feels like mid-70s Fahrenheit—comfortable but warm enough that runners should consider lightweight clothing. Humidity levels at about 73.6% mean moisture will be present in the air.
