The Longest Day
The Longest Day is an elimination-format trail event held at The Preserve at Lakewood in Greenville, SC. Runners complete repeated 2-mile loops on grass trails that pass through 120 acres of forest, rolling fields, and shaded sections. The course runs through stands of red cedar and maple and offers regular wildlife sightings such as white-tailed deer, box turtles, foxes, and various songbirds.
All runners begin each lap together. Each lap has a progressively shorter cutoff time: Lap 1 has a 45-minute cutoff, Lap 2 a 44-minute cutoff, Lap 3 a 43-minute cutoff, and so on, with every subsequent lap one minute shorter than the previous. Individual lap times are not recorded; missing a cutoff ends a participant’s race. If more than one runner reaches the final lap, the first across the finish line wins.
The event includes multiple distance targets defined by lap counts:
- Half marathon (13.1) - 7 laps
- Marathon (26.2) - 14 laps
- 50K - 16 laps
- 50 miles - 25 laps
- 100K - 31 laps
A simple aid station provides pickles, cookies, candy, water, coke, and ginger ale. This is a cup-free event; participants should bring a bottle, hydration vest, or reusable cup. There is no water or power on site. Registration opens 2026-09-01, closes 2027-01-05, and the listed registration fee is $40.00. Visit the organization's website for the most recent information.
