The Longest Day 100k

Greenville, United States • 13 Jun 2026

Overview

The Longest Day takes place at The Preserve at Lakewood in Greenville, South Carolina. The race utilizes a 2 mile loop format where participants compete on a grass trail featuring rolling hills and partial shade. The event begins at sunrise and continues through sunset, set within 120 acres of forest and grass paths home to local wildlife such as white-tailed deer, box turtles, and foxes.

Competition Format

This event features a unique eliminatory format where participants must complete each 2 mile lap within a specific time limit. The first lap allows 45 minutes for completion. For every subsequent lap, the time limit decreases by one minute. Runners who fail to complete a lap within the allotted time must ring a cowbell and exit the course. If participants reach Lap 31, the first runner to cross the finish line is declared the winner.

The event offers several distance goals for participants to target:

  • 13.1 miles
  • 26.2 miles
  • 50 km
  • 50 miles
  • 100 km

Facilities and Logistics

The race is a cup-less event, requiring participants to bring their own bottles or cups for hydration. An aid station provides water, soda, ginger ale, and snacks such as pickles, cookies, and candy. Participants are permitted to set up 10x10 tents and camp chairs near the start and finish line to establish a home base for their crew. Overnight camping options and early tent setup are available on the Friday evening before the race. Packet pickup is held on-site one hour before the race begins.
