Welcome to the Williams Grove Half-Mile.

Progressive American Flat Track returns to one of the most legendary dirt tracks in American motorsports history. On Saturday, May 23, 2026, the world's best flat track motorcycle racers descend on Williams Grove Speedway in Mechanicsburg, Pennsylvania, for Round 7 of the Progressive AFT Championship.

A Track Steeped in History

Williams Grove Speedway isn't just a racetrack. It's a living piece of American motorsports history. Since opening on May 21, 1939, the half-mile banked clay oval has hosted virtually every major national touring series on two and four wheels. From the American Automobile Association to the American Motorcyclist Association, USAC to NASCAR, the World of Outlaws to now Progressive American Flat Track, the legends of racing have all turned laps at The Grove. Names like Tommy Hinnershitz, A.J. Foyt, Mario Andretti, and countless others have raced on this hallowed Pennsylvania dirt. The track has been owned by the Hughes family for over 50 years and remains one of the most iconic racing facilities on the East Coast.

The Racing

Half-Mile races have been the most common circuits on the Progressive AFT schedule throughout the history of the sport, and Williams Grove is one of the best. The half-mile format produces intense, high-speed competition where riders push their machines to the limit on every lap.

Watch the premier Mission AFT SuperTwins class, the pinnacle of dirt track motorcycle racing, featuring production-based twin-cylinder motorcycles (649-900cc) piloted by the fastest athletes on dirt. These are the biggest names in the sport, battling bar-to-bar at speeds that will leave you breathless. The KICKER AFT Singles class showcases the next generation of flat track stars aboard production-based 450cc machines specially prepared for competition. And with the Royal Enfield Build. Train. Race. program making an appearance at Williams Grove, you'll also witness the all-women class that continues to elevate aspiring women racers and inspire fans across all generations.

What is Flat Track Racing?

Flat track is America's original extreme sport, the oldest and purest form of motorcycle racing in the country. The formula is simple: oval dirt track, no front brakes, and the throttle wide open. Riders slide into corners at incredible speeds, fighting for position with nothing but skill, bravery, and a steel shoe scraping the dirt. It's high speeds, close quarters, and nonstop action from the drop of the green flag to the final checkered flag. Whether you've been a fan for decades or you're experiencing it for the first time, you'll understand immediately why this sport has captivated audiences for over a century.

Half-Mile Racing

The half-mile format is where flat track racing truly shines. Larger than the tight confines of a short track but more technical than the high-speed drafting battles of the mile ovals, half-miles reward a complete rider, one who can carry speed through the corners, set up passes with precision, and manage their equipment over the course of a grueling main event. Williams Grove's banked clay surface adds another dimension, with speeds exceeding 100 mph and racing lines that evolve throughout the day as the track changes.

The Atmosphere

There's nothing quite like race day at Williams Grove. The smell of race fuel and dirt. The thunder of twin-cylinder engines echoing off the grandstands. The roar of the crowd as riders slide through the corners wheel-to-wheel. This is motorsports the way it was meant to be experienced: raw, real, and live.

Beyond the on-track action, fans can explore vendor displays, enjoy great food and drinks, and soak in the electric atmosphere of a Progressive AFT event. The open paddock gives you a chance to see the bikes up close and watch the teams prepare for battle. It's a full day of entertainment for fans of all ages.

Central Pennsylvania: The Heart of Dirt Track Racing

Williams Grove sits in the heart of Central Pennsylvania, a region with deep roots in dirt track racing. The area has produced and developed some of the greatest drivers in motorsports history, and the passionate local fans are known throughout the racing world.
