Grand Slam of Ultrarunning Series

The Grand Slam of Ultrarunning Series is a prestigious event that challenges runners to complete five of the oldest 100-mile trail runs in the country: 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. To be eligible for the award, participants must officially complete three of the first four Grand Slam Series races and then complete the Wasatch Front 100 Mile Endurance Run in the same summer.

The Wasatch Front 100 Mile Endurance Run is the final race of the series and hosts the Grand Slam of Ultrarunning Awards ceremony.

No late applications will be accepted.

The event's current local time is 9:19 PM ET.
