The Hamilton County Fair in Webster City, Iowa, is excited to announce that Todd and Janet Staley's TTMM Promotions will host a series of races in 2025, keeping the spirit of racing alive at the historic  Karl Chevrolet Hamilton County Speedway.

"From having the opportunity to work at the speedway to being , one of the biggest things I hear is 'I would hate to see the speedway close,'” said Zach Williams, President of the Hamilton County Fairboard. "Well, the way to keep that from happening is to go enjoy a Saturday night at the Hamilton County Speedway. Butts in the seats is what will keep this place going. Todd does his best to put on a great show."

All USRA-sanctioned classes will compete in the Summit USRA Weekly Racing Series, and the 2025 season will see Karl Chevrolet return as the title sponsor of the track.

The Summit USMTS National championship presented by Racindirt will bring a high-stakes two-day event with the 15th Annual USMTS Spring Classic on Friday and Saturday, April 11-12, with a purse exceeding $60,000 for outlaw dirt Modifieds and offering $5,000 to win each night.

The reborn USRA Stock Car Iron Man Series will also have a doubleheader two weeks later on Friday and Saturday, April 25-26, with over $25,000 in payouts including $1,200 and $2,000 to win, respectively for the USRA Stock Cars.

The DTRA Dirt Truck Series is scheduled for three appearances on April 26, June 28 and July 26.

June will kick off with the Flaws Brothers Memorial featuring the USRA Northern Lights Modified Series and USRA Stock Car Iron Man Series. On Saturday, June 28, the Bill Rice Memorial featuring the Tri-State Late Model Series is on tap.

Hamilton County Fair week runs from July 24-27 and will be packed with events, starting with Thursday Night Thunder featuring the Malvern Bank SLMR Super Late Model Series. Friday night's event is still open while Saturday will host the Hall of Fame Induction and Kids Night. The week of excitement wraps up with Sunday's Eve of Destruction Trailer Races.

The season will conclude with the 2nd Annual Mike Baker Memorial on August 16. Depending on how the season unfolds, the long-running Fall Futurity is tentatively slated for October.

Opening in July 1910, the Karl Chevrolet Hamilton County Speedway is the oldest speedway in the state of Iowa. In 1938, work began on the current location at the Hamilton County Fairgrounds. The semi-banked half-mile dirt track was completed in the spring of 1939, and the first races were held on the track in September of that year.

The Karl Chevrolet Hamilton County Speedway is located off US 20 at exit 140, then 1.2 miles north, then 0.5 mile east on Bank St., then 0.4 mile south on Bluff St. to the Hamilton County Fairgrounds in Webster City, Iowa. The physical address is 1200 Bluff St, Webster City, IA 50595.
