Grand Slam of Ultrarunning
From WikiRun
The Grand Slam of Ultrarunning is a set of four of the most renown 100 mile races contested in the United States, comprising the Western States 100 in California, the Vermont 100 Mile Endurance Run in Vermont, the Wasatch Front 100 Mile Endurance Run in Utah, and the Leadville Trail 100 in Colorado. A small number of people manage to complete all four in the same calendar year.
Another series of four ultramarathons, all held near the Artic Circle has been dubbed "the Artic Grand Slam."[1]
