Hardrock Hundred Endurance Run

Starters are picked in an early-December lottery, and you can only apply, during a two-week October window, if you've finished one of Hardrock's approved mountain qualifying races. The draw has two pools: runners who have never finished Hardrock get tickets that double with each year they miss out, while past finishers gain a ticket per finish and per missed year, and volunteer service tickets boost both. Everyone who gets a spot must also log eight hours of trail work or ultra volunteering by mid-June of race year.
