The track was originally built in 1947 as a
dirt oval by Arthur Fleury, an
active duty service member for the
army who proposed the idea of building a racetrack in his neighborhood. It was built on the site of his father's farmland, and began hosting races that year under the name
Claremont Speedway. After a few years, the track went under new management from a group known as the Jalopy Association. In the mid-1960s, Arthur's brother Sonny Fleury took over ownership of the track. He paved the facility in 1973 as a oval and has been run on that surface since then. The track was briefly owned by the Claremont Owners Drivers Association (CODA) from 1980 to 1985, until it was sold back to Sonny for the 1986 season. Following Sonny's death in 1993, his daughter Sherrie and husband James Laneau took over track operations. Dennis Fleury, Sonny's nephew and Arthur's son, bought the track in 2004, renaming it
Twin State Speedway. In December 2014, Jim Ambrose, along with a group of investors, purchased the track from Dennis and renamed it back to
Claremont Speedway. During Ambrose's management in 2016, he made a proposal for a smaller campground, which was approved by the Zoning Board of Adjustment on October 3. On February 25, 2019, it was announced that Ambrose had sold the track to a New Hampshire ownership group consisting of Norman Wrenn Jr. and Ben Bosowski, renaming it
Claremont Motorsports Park. They also operated other tracks in the state, including Hudson Speedway,
Lee USA Speedway, and
Monadnock Speedway. After only one season, Wrenn and Bosowski sold the track to focus on other racing properties. Mike Parks and MDP Motorsports Promotions began leasing the track for the 2020 season. Bosowski returned in 2023 as the sole owner and continued to lease the track occasionally to Parks. In July 2024, the track was severely damaged following a powerful and destructive windstorm. Community members from Claremont and surrounding cities, along with several local businesses, volunteered to help with clean-up efforts, and racing activities were able to continue for that weekend's Friday events. On August 21, 2025, it was announced that MDP Motorsports Promotions would assume full day-to-day operations of the track beginning on November 1. == Events ==
