RunStrong Event's signature 24 hour challenge, Death by 5k requires participants to run ten 5ks starting every 2.5 hours. The first 5k starts at 8 am, and subsequent 5ks start at 1030, 1, 330, 6, 830, 11, 130, 4, and 630 am. Participants need to be present at the start of each 5k, and have that 5k finished prior to the start of the subsequent 5k. This challenge is designed to test participants mentally and physically with physical fatigue, sleep deprivation, and running in the dark. (Headlamps, hand lights, or some other form of illumination will be required)

Death by 5k Memphis will start and finish from the Tour de Wolf Pavilion at Shelby Farms, and will be run almost entirely on the Tour de Wolf trail. (There will be a short stretch of road running from the pavilion to the trailhead at the start of each 5k). The course will be mostly a loop with a small stretch midway that may be out and back.
