About the race

Summer Sundown Rundown takes place in Kempton, PA on July 31, 2027. The event is a trail run held as part of a summer camp program. The format is described as a negative split endurance challenge. Laps are run in sequence and each lap has a specific start time that applies to all participants.

If a runner misses the assigned start time for the next lap, that runner is eliminated from further laps. Laps continue under this rule until only one participant remains. The description focuses on the race format and elimination structure rather than distance or course details. The setting is a trail environment and the event is organized as a series of timed lap starts with progressive elimination. Visit the organization's website for the most recent information.
