Leicester and Swindon have been chosen as the final two venues to stage this season's major speedway events.
Premier League newcomers Leicester opened up to a 4,500 crowd at Beaumont Park on Saturday and will now host the Premier League Fours on 7 August.
Swindon will stage the Elite League Riders' Championship on 15 October.
Series co-ordinator David Hoggart said: "I was very impressed by the track and facilities at Leicester on a hugely successful opening night."
He added: "Swindon is a very worthy venue for a top meeting like the Elite League Riders' Championship in October."
Leicester Lions owner David Hemsley used his life savings to bring a speedway team to the city for the first time since 1983.
