Here are 6 of the top 100-mile races in North America
Western States Endurance Run
The Western States Endurance Run is the oldest and most prestigious 100-mile race in the world, attracting elite runners from all over the globe.

Sinister 7 Ultra
The 100-mile and 50-mile courses take runners on memorable, seriously rugged, remote and beautiful terrain in the Rocky Mountains of Alberta. There is a staggering 6,600m of elevation gain across the 100-mile course, so come prepared or you will be punished. Once athletes pass about the 15 hour mark they will be running in the dark, which only adds to the challenge of the race. “The Sinister 7 is as mentally demanding as it is physically grueling. When you have been running for hours on end, your mind will give you a million reasons to quit - you have to decide that it is more important to finish,” warns race director Brian Gallant.
