Endless Summer 2026

The race.

The Endless Summer running fest takes place June 20–21, 2026, at Catfish Lake in Birmingham, AL. Runners choose a 6-, 12-, 18-, 24-, 30-, or 36-hour duration and complete as many 1-mile loops as possible on a dirt and gravel loop with a brief grass section and approximately 120 feet of elevation change. The start and finish are at Catfish Lake, with parking at Belcher Tract off 280 and a 0.8-mile walk or jog to the course. Packet pickup occurs Thursday, June 18, 5–8 PM at The Red Shamrock Pub. All runners receive a tank top and sticker; top three male and female finishers in each duration earn awards, with a buckle for those reaching 100+ miles. Aid stations operate continuously at the start/finish, with meals served at set times both days. Award ceremonies follow each duration's completion.
