Disclosure and History of the Grand Slam of Ultrarunning

The idea of running the four oldest 100 mile trail runs in the country came from Fred Pilon of Ultrarunning Magazine back in 1985. He called Steve Baugh who was the race director of the Wasatch Front 100 Mile Endurance Run at the time. Since Wasatch was the final race of the four, it seemed natural for the Wasatch 100 to organize the Grand Slam and have awards in conjunction with Wasatch’s awards ceremony. Steve collaborated with John Grobben, current and long standing Wasatch 100 race director, and they came up with the name Grand Slam of Ultrarunning. The award was established in cooperation with the race directors of the other four races involved at that time. The first Grand Slam Award was given to Tom Green in 1986. The Wasatch Front 100 Mile Endurance Run has continued to organize and manage the event since that time.

Grand Slam of Ultrarunning Series

We now have five races in the Grand Slam of Ultrarunning Series: Old Dominion 100 Mile Endurance Run, Western States 100 Mile Endurance Run, Vermont 100 Endurance Race, Leadville Trail 100 Run, and Wasatch Front 100 Mile endurance Run. In order to be eligible for the award, participants must officially complete three of the four first Grand Slam Series races and then complete the Wasatch Front 100 Mile Endurance Run all in the same summer. Grand Slam hopefuls must apply for the Wasatch Front 100 Mile Endurance Run in a timely manner as do all other entrants. This means applying in the approximate one month period running from December 1st through the following January 4th. ABSOLUTELY NO LATE APPLICATIONS WILL BE ACCEPTED! The Wasatch Front 100 Mile Endurance Run is required because it is the final race of the series. The Grand Slam of Ultrarunning Awards are presented at this race and the series is organized by the Wasatch Front 100 Mile Endurance Run Race Committee.
