The Longest Day 100k

The Longest Day is a multi-distance event held on June 12, 2027 at Lakewood Nature Preserve in Greenville, SC (220 Lakewood Drive). Runners complete repeated laps of a two mile grass loop that winds through 120 acres of forest and open field with rolling hills, red cedar and maple, and sections of shade. Wildlife such as white-tailed deer, box turtles, and foxes may be seen along the course.

Distances offered

  • 13.1 miles : 7 laps
  • 26.2 miles : 14 laps
  • 50K : 16 laps
  • 50 miles : 25 laps
  • 100K : 31 laps

The event uses an elimination format: each lap has a cutoff that shortens by one minute per lap, from 45 minutes on Lap 1 down to 15 minutes on Lap 31. Miss a cutoff, ring the cowbell, turn in the bib, and the runner is finished. The barn serves as start/finish and the on-course aid location; participants may set up personal tents and leave gear in the barn between laps. There is no water or power on site, and the event is cup-less so runners should bring their own hydration vessel. Friday evening tent setup and overnight camping are available. All finishers who cover at least 10K receive a medal. Age group awards and series recognition are offered, and the event supports Children's Cancer Partners of the Carolinas.
