Harry Cook took the HEL Performance British Junior Supersport with Motocourse race win after a bold three-way scrap to the finish line.
Cook pipped Mikey Hardie by 0.037s with James McManus just 0.008s further back after a dramatic last lap of place swapping between the trio.
Kieran Kent ended the race fourth ahead of Chris Moffitt, as championship leader Charlie Atkins crashed out and polesitter Charlotte Marcuzzo – the first ever female to start a JSS race from P1, also crashed after tangling with another rider.
