The automotive community in Hamilton and Boone County is revving up for an action-packed season with two thrilling events: the SpringFling! 10000 and One Hundred Over 31: A Supercar Gathering. Both events, organized by Artomobilia Executive Director and Founder John Leonard and his team, promise to bring car enthusiasts together for unforgettable experiences featuring scenic drives, stunning supercars and a vibrant festival atmosphere.
SpringFling! 10000: A Road Rally With a Purpose
Mark your calendars for Saturday, April 26, as the highly anticipated SpringFling! 10000 makes its return, offering a 90-minute rally through the breathtaking roads of Hamilton and Boone County. This rally isn’t just about the drive — it’s an opportunity to reconnect with fellow automotive enthusiasts and support local charities.
The event kicks off at St. Vincent Carmel, with two run groups departing at 10 a.m. and 10:30 a.m. Participants will navigate a specially curated route before arriving at Motor District in Westfield, where they can enjoy live entertainment, garage tours and an impressive lineup of cars on display. The event will conclude at 2 p.m., giving attendees ample time to soak in the sights and sounds of this automotive celebration.
“We’ll start in Carmel, find the best roads in Hamilton and Boone County, and end up over at the Motor District, where we’ll have food trucks, music and more,” Leonard said. “For an ad-hoc car show, people can just hang out, grab a beer — Danny Boy Beer Works is involved.”
Entry fees for the rally are $35 per vehicle, with 100% of proceeds benefiting the charities designated by Motor District Owners Association members. Whether you’re a seasoned rally participant or a first-time driver, SpringFling! 10000 is the perfect way to hit the road and give back to the community.
One Hundred Over 31: A Supercar Gathering
One Hundred Over 31: A Supercar Gathering is a must-see event for enthusiasts of high-performance machines. Set against the backdrop of Carmel’s distinctive roadways and signature roundabouts, this extraordinary showcase takes place on Friday, May 3, from 5:30-8:30 p.m. The West Carmel Drive Bridge, which spans U.S. 31, will be transformed into a striking display of 100 supercars representing decades of automotive excellence. With Carmel’s vibrant commercial corridor providing ample space for thousands of guests, attendees will have the opportunity to admire both the city’s renowned infrastructure and the exceptional vehicles on display.
“This event is called ‘100 over 31’ because it takes place along the West Carmel Drive Bridge that goes over U.S. 31,” Leonard explained. “It’s a straight-up gathering — no drive — where people can come out, see an amazing variety of supercars and enjoy a great time.”
Unlike traditional car shows that focus solely on modern exotics, 100/31 will feature supercars from different eras, including 1970s and 1980s classics, 1990s icons and the latest high-tech speed machines. Attendees can admire everything from a vintage Ferrari 308 GTS (a la “Magnum P.I.”) to a cutting-edge Lamborghini Aventador with 700 horsepower.
In addition to the incredible lineup of vehicles, the event will feature food trucks, live music and a vibrant festival atmosphere. With its unique location, rare and exotic cars, and a strong sense of community, 100/31 is shaping up to be one of the most exciting automotive gatherings in Indiana.
A Season Packed With Automotive Excitement
While SpringFling! 10000 and 100/31 are the first major events on the calendar, Leonard and his team have more in store for automotive enthusiasts in Hamilton County. Events like the Hamilton County Scavenger Hunt and GarageLife! will provide even more opportunities for car lovers to engage with the community, explore unique vehicles and celebrate automotive culture.
“My intent is that the Hamilton County Scavenger Hunt is kind of an ad-hoc road rally,” Leonard shared. “We’ll start somewhere; everyone picks the direction they want to go; they collect ten or so items in terms of photography, and then we return to Motor District to wrap it up.”
Meanwhile, GarageLife!, scheduled for June 21-22, will offer a behind-the-scenes look at some of the most impressive garages and automotive spaces in the region. Inspired by the Home-A-Rama concept, this event will highlight not only cars but also cutting-edge garage designs, collector car galleries and automotive-inspired workspaces.
For now, though, the focus is on the SpringFling! 10000 and 100/31, two must-attend events for any car enthusiast looking to kick off the season in style. Whether you’re driving, displaying or simply spectating, these gatherings promise high-octane excitement, community engagement and a great way to celebrate a passion for cars.
