Speedway

In 1971 a speedway practice track was built on farmland owned by Terry Waters and two years later on the same farmland the track was moved to the south side of the junction where Hayland Drove meets Cooks Drove. The track was extremely primitive with a few sheds used as dressing rooms and straw bales made up the safety fence. In 1975 the Mildenhall Fen Tigers were formed and they entered the National League.^[4]

Greyhound racing

In August 1990, Dick Partridge approached Terry Waters regarding a return for speedway and the introduction of greyhound racing. A lease was agreed and the greyhound track was constructed along with improvements in the facilities including new concrete terracing and track lights. The hare was an 'Outside Sumner' and the sand that made the surface was the King's Lynn silica sand. Seventy-four kennels were constructed with a paddock and weighing room added in an area of the old speedway pits. After securing a licence from the National Greyhound Racing Club the first meeting took place on Saturday 21 September 1991.^[5] An eight race card started with a 375 metres event that was won by Coppacabana a 3-1 shot trained by Mills in a time of 24.61 secs.^[6]

The stadium suffered a two-month closure in the early part of 1992 before re-opening under new management headed by Denis Diffley.^[7] In 1995 Terry Waters took over from Dick Partridge who suffered financial difficulties.^[8]

One of the sports leading trainers Linda Jones from nearby Lakenheath attended the track regularly whilst establishing the Imperial Kennels.^[9] Tuesday and Saturday night racing became regular nights with other race distances in addition to 375 being 550 & 700 metres.

Later the greyhound racing was then overseen by Richard Borthwick and Michael Glynn and new Racing Manager was Michael Hill. Mildenhall underwent changes again with distances being fine-tuned to 220, 375, 545, 700, 870 & 1025 metres on a circumference of 325m. Terry Waters took over as General Manager at the turn of the millennium^[10] and in 2008 Dave and Ron Coventry took over^[11] followed by Richard Borthwick.

Controversy and sale

In 2006, a couple bought a house close to Mildenhall Stadium where stock car racing and speedway have taken place since 1975, and began complaining about the noise. The couple took the stadium to court in 2014 and won resulting in the threat of closure for the stadium.^[12] In between the track experienced a temporary suspension following the exit of promoter Carl Harris.^[13] In 2016, the stadium was sold to Deane Wood of Spedeworth Motorsports.^[14]

Greyhound racing closure and return

Greyhound racing was held every Tuesday and Friday night (all year round) but on 15 January 2018 it was announced that the racing would cease. With the ongoing problems experienced by the track, the majority of its biggest trainers left for Crayford Stadium, Henlow Stadium and Harlow Stadium, which resulted in racing only being held one night per week before the closure.^[15] In 2020, Kevin Boothby (the Towcester promoter) announced the return of racing and renamed the stadium Suffolk Downs.^[16] The first trial session took place on 12 January 2022.^[17]

When racing returned the first meeting was held on 8 February 2022, with the primary race distance being 388 metres.^[2] Mark Wallis joined the stadium training ranks during 2023 and won his 14th Greyhound Trainer of the Year title after recording 1591 points.^[18]
