The 2021 GB3 Championship visits Donington Park this weekend (16/17 October), with the Leicestershire circuit hosting what is still mathematically a title race going into the final meeting of the season.
The series supports the Intelligent Money British GT Championship, which has several titles of its own still up for grabs this weekend.
TCF takes a look at the stories going into the season finale, and what they mean for next season.
What happened last time at Donington?
Wins in Race 1 & 2 for O’Sullivan, Mikkel Grundtvig took only win of the season so far for Fortec Motorsport in Race 3.
GB3’s first visit to Donington this season in July, when the series was still called British F3, brought two wins for Champion-elect Zak O’Sullivan after the Carlin man took pole for Race 1 and 2, putting him last for Race 3 which brought retirement after a clash with then-title rival Reece Ushijima in Sector 3.
