FIM Speedway of Nations winner Jack Holder continued his red-hot run of form after inspiring Australia to world-title gold by topping the FIM Speedway GP of Great Britain – Cardiff Qualifying Practice charts on Friday.

The Sheffield and Torun star clocked a fastest lap of 12.809 seconds to earn first pick of starting positions for Cardiff’s 20th anniversary FIM British Speedway GP on Saturday (5pm BST).

Holder’s older brother Chris won the 10th anniversary event in 2010, as well as the 2012 FIM British Speedway GP on his way to world-title glory.

Jack starts his own quest for Cardiff victory in race two from gate one, taking on 2019 winner Leon Madsen, GB star Robert Lambert and wild card Adam Ellis.

Holder comes up against his fellow FIM SON winner Max Fricke in race 15, taking on Polish duo Bartosz Zmarzlik and Pawel Przedpelski.

Speedway GP World Championship leader Zmarzlik finished ninth on the timing charts with 13.010 seconds as he bids to improve on his 18-point lead at the top of the standings.

He comes up against second-placed Leon Madsen in a strong heat six, which pits them against Teterow winner Patryk Dudek and European champion Mikkel Michelsen.

Dan Bewley was the fastest home rider in Qualifying Practice, taking second place on 12.810 seconds. His night gets underway in race four against Freddie Lindgren, Fricke and Michelsen.

Lambert took fourth place on 12.909 seconds, while triple world champion Tai Woffinden was placed 11th on 13.029 seconds. The Brits face off in heat eight, with Aussie duo Jason Doyle and Max Fricke joining them at the tapes.

There will be three Brits on track in heat 12, which sees Woffinden meet Wroclaw team mate Bewley and Ellis, with 2018 Cardiff winner Zmarzlik completing a blockbuster line-up.
