The latest races in the GP2 Championship held mixed emotions for the two local teams with Timo Glock first losing his championship lead before regaining it with a splendid victory in race two.

The top three places on the grid for the opening race belonged to the Norfolk squads with Luca Filippi on pole position for the Griston-based Super Nova outfit with the next two places occupied by Glock and his team-mate in the Carlton Rode iSport team, Andi Zuber.

At the start Zuber made a blinding start to slice between his two rivals but Mike Conway, Super Nova's second driver, spun at the opening corner causing mayhem behind.

To complete an unhappy day for the David Sears-run team Filippi spun out of third place causing the deployment of the safety car.

With Zuber pitting Glock had to stay out behind the course car, which cost him dearly. As the race unfolded Zuber looked to be heading for victory until he spun, badly damaging his car.

Glock made his pit stop five laps from the end, handing the lead and victory to his title rival Lucas di Grassi while the local driver had to settle for fourth place.

In the second race Glock made quick progress to be third after just a few laps and shortly after was handed the lead when the two drivers ahead of him collided.

“This win is for the mechanics who did a perfect job overnight to fix Andi's car, they worked until three in the morning,” said Glock afterwards.

Filippi fought his way from the back of the grid to seventh while Zuber posted the fastest lap of the race after starting from the pit lane.

Meanwhile, Daniel Laddiman bounced back into form with a brace of podium places in the latest rounds of the Ginetta Sportscar Championship at Thruxton.

The Horstead youngster, recently handicapped with engine and transmission problems, secured third place on the grid for race one.

In the tight battle for victory Laddiman led on several occasions before securing third place on the final lap having passed Spencer McCarthy.

In the second race the local racer narrowly failed to dislodge winner Matt Nichol-Jones in a four-car blanket finish having started from 6pole position.

In the third race, a replacement for an early season missed event, Laddiman didn't fare as well when an early incident dropped him down the race order from which he fought back to take 10th place.

“Overall it wasn't a bad event,” declared Laddiman. “I'm only four points off second place having gained 38 points this weekend.”

James Blyth suffered a tough time in the latest races in the Mini Challenge at the Croft Circuit in Yorkshire.

The Brundall racer could only qualify in 15th place for the opening race, after mechanical problems, improving to 10th place by the end of the race.

Starting from the back of the grid for race two Blyth was an early retiree having made up 12 places on the opening lap.
