Philadelphia to Host Unprecedented 12-Hour Sebring Race Celebration for America's 250th Anniversary

PHILADELPHIA, PA – March 05, 2026 – As the roar of engines prepares to fill the air in central Florida for one of motorsport's most grueling contests, a parallel celebration of American racing history will unfold nearly a thousand miles away. The Simeone Foundation Automotive Museum announced it will host "Once Around the Clock: The Simeone 12 Hours of Sebring," an ambitious 12-hour event on Saturday, March 21, 2026. Running in lockstep with the actual 12 Hours of Sebring, the Philadelphia-based event offers a unique, immersive experience that stands as the only Sebring celebration of its kind happening outside of Florida.

This unique tribute is strategically timed to coincide with the United States' Semiquincentennial, or 250th anniversary. As the nation reflects on its history, the Simeone Museum is positioning American automotive ingenuity and competitive spirit as a key part of that legacy. By bringing the spirit of Sebring to the birthplace of America, the museum is crafting a narrative that connects the country's foundational ideals with its 20th-century industrial and sporting prowess.

A Rolling History of American Endurance

The event is far more than a simple watch party. It is a meticulously curated journey through the annals of America's oldest and most demanding endurance race. From 10:00 AM to 10:00 PM, the museum will present seven distinct themed sessions, each dedicated to a pivotal era of Sebring's storied past. More than two dozen historically significant race cars from the museum's world-renowned collection will be brought to life, their engines thundering on the museum's 3.5-acre tarmac in live demonstrations.

"Since 1950, Sebring has been America's proving ground," said Kevin Kelly, Executive Director of the Simeone Foundation Automotive Museum, in a statement. "It's where American builders, drivers, and engineers proved they could compete with the world's best. As we mark America's 250th anniversary, this event honors that spirit of competition and innovation."

The day's programming will begin by revisiting the shocking 1950 victory of a humble Crosley, moving through the establishment of the first true 12-hour format in 1952. A key session will focus on America's breakthrough in 1953 with Briggs Cunningham's C4R, a moment that signaled the arrival of American constructors on the world stage. Subsequent sessions will explore the clash of Detroit muscle against refined European machinery, the legendary factory battles between Jaguar and Ferrari, and the dominant era of Carroll Shelby's iconic Cobra Daytona Coupe, culminating in a final parade of champions.

Each two-hour block will feature indoor presentations enriched with rare archival footage, followed by the outdoor demonstrations. These sessions are designed to be interactive, with audience Q&A opportunities and ample time for photography, allowing attendees to get closer to the machines that forged Sebring's legacy.

Beyond the Static Display: An Immersive Experience

This event represents a deliberate move away from the traditional, static museum model. Building on the success of its 2025 "24 Heures du Simeone" Le Mans celebration, which drew over 1,000 attendees, the museum is doubling down on a formula that prioritizes dynamic engagement and immersive storytelling. The goal is to recreate the vibrant, evolving atmosphere of the Sebring infield from the 1950s through the 1970s.

Period-correct signage, a vintage soundtrack, and staff dressed in era-appropriate racing attire will transport visitors back in time. Meanwhile, ten large screens placed throughout the facility will provide continuous, live coverage of the ongoing race in Florida, ensuring a constant connection to the present-day drama. This dual focus on past and present creates a unique temporal tapestry for motorsport enthusiasts.

"This isn't a static display," Kelly noted. "Guests who stay for multiple sessions will see the event evolve. The atmosphere intensifies as the race builds. We've built surprises into the program that reward those who commit to the full experience." This approach suggests that the day is structured as an endurance event for fans as well as cars, with the experience deepening as the hours tick by and the sun sets, mirroring the challenges faced by drivers on the actual track.

Philadelphia's Engine for a National Celebration

By hosting this singular event, the Simeone Museum is not only celebrating automotive history but also cementing Philadelphia's role as a central hub for the America250 commemorations. While the city's colonial landmarks will undoubtedly be a focal point, this event highlights a different, yet equally important, facet of the American story: the drive to innovate, compete, and win. It provides a significant cultural draw that is expected to attract visitors from across the region and the nation, boosting local tourism.

The event's status as the sole Sebring-focused celebration outside of Florida makes it a destination for racing fans who cannot make the trip to the Sunshine State. For a single ticket price of $20 for adults—with children under 11 and museum members admitted for free—attendees can access a full day of sights, sounds, and history. With food vendors on-site and free parking, the museum has organized a comprehensive, accessible event for families, historians, and gearheads alike.

As the clock ticks down on March 21, both in Florida and in Philadelphia, attendees at the Simeone Museum will be part of a unique confluence of history. They will witness the legends of the past roar back to life while watching the champions of the future be forged in real-time, creating a powerful and unforgettable tribute to 12 hours of American grit.
