In the endurance world, a Grand Slam is the successful completion of a specific, prestigious series of ultra-distance events. Borrowed from the world of bridge and later popularized by baseball and tennis, the “Slam” represents the ultimate collection of trophies.
In ultra cycling, the Vegas In 24 Grand Slam is a legendary feat. Athletes must ride all four distinct routes, ranging from 346 to 448 miles, featuring as much as 19.4K feet of elevation gain, and officially finish at least three of them within the strict 24-hour cutoff. Those who conquer this unsupported desert gauntlet which Škoda recognizes as an “Epic Ride” and “nonstop cycling spectacle,” earn a permanent seat in the Vegas In 24 Hall of Fame, a testament to their resilience against heat, wind, and the relentless ticking of the clock.
In Ultra-Running, the Grand Slam is one of the oldest and most respected honors in endurance sports. It consists of finishing four of the five most historic 100-mile trail races in the United States: the Old Dominion 100, Western States 100, Vermont 100, and Leadville Trail 100, with the Wasatch Front 100 serving as the mandatory final leg. Covering over 400 miles of rugged terrain—from the “Race Across the Sky” in Colorado to the sweltering canyons of California—the Grand Slam is the definitive benchmark of the all-around mountain runner.
