Race Info
About the Devil After Dark Race: Over the years, one of my favorite times at our Running with the Devil extreme heat race in late June is when the sun sets, and the night air just beckons you to be outside and run! Devil After Dark brings you that magic with a late summer evening run.
Commencing just before sunset, run through Lovell Canyon while enjoying the stunning sunset as day falls into night. Sun is replaced by stars and moonlight lights the way. The omnipresence of the surrounding canyon under the moonlit starry night is magical! Pinion Juniper trees dance in the shadows and the neon lights of Las Vegas are just minutes away. An enchanted late summer evening run. Source
