TROY Batchelor’s British Grand Prix ended in the back of an ambulance as he crashed out in heat 16, before Niels-Kristian Iversen picked up the event win at Cardiff's Millennium Stadium.

Former Robins’ number one Peter Kildemand rode a fantastic semi-final and earned himself a third placed finish and 12 GP points.

For the Robins’ skipper the meeting had started very well, as he won his opening heat, but Batchelor then struggled for points thereafter, ending with just four.

Chasing a win in his fifth run as he tried make the semi-final he tried to pass Chris Harris on the outside and went down hard into the air fence.

The Aussie star was eventually driven off the track in an ambulance and could not complete his final heat.

Robins fans had to wait until heat four to see their skipper, Batchelor, and former number one, Kildemand, in action. They lined up with GP leader and home favourite Tai Woffinden and Tomas H Jonasson.

It was a great start for the Swindon skipper as he made a great gate from the inside and streaked away to pick up three valuable Grand Prix points.

Behind him Kildemand kicked off his career as a permanent rider in the series with a handy two points.

The real action was at the back as Jonasson managed to hold off Woffinden to deny the British champion a point in his first heat of the night.

Kildemand was back in action in heat six with the favourable gate one. He looked to have made the most of it but was knocked off on bend two of the second lap by Jason Doyle.

The Aussie was excluded and in the re-run, after a fight in the first corner involving all three riders, Kildemand rode away to pick up three points, Iversen second, Craig Cook third.

In the next heat Batchelor wrestled with his bike and the Slovenian Matej Zagar, but ultimately lost out and had to settle for third after a slip coming out of the last bend.

Batchelor struggled from gate three in heat 10. The Robins’ skipper was passed on the first bend and could not find a way past Doyle and ended scoreless for the first time on the night.

Kildemand dealt better with the outside gate, taking second place as Holder won from three. Andreas Jonsson and Kryztof Kasprzak completed the results.

It meant that after 12 heats Batchelor was just outside the qualification spots for the semi-final, but Kildemand was looking good to progress. With the Aussie going from four next it would take a big effort to make the last eight.

The former Swindon number one was on the end of a hard move from Pedersen in heat 13. The former world champion was excluded, allowing Kildemand a clearer run from gate three.

However he could only manage third as Zagar held off Hancock.

Things took a bad turn for Batchelor in heat 16 as he came off trying to catch Harris and spun into the air fence hard. The ambulance was called for and Batchelor was taken to hospital for treatment, ending his night.

Hancock and Woffinden topped the standings after 20 heats, with Kildemand progressing in fifth place. The Dane picked gate four for his second semi final as he tried to find a way past Jepsen Jensen, Hancock and Woffinden.

It was an inspired choice as Kildemand passed Hancock on the second lap, diving under the American to make the final.

With Woffinden winning the second semi-final, Kildemand lined up with first semi winner holder and runner-up Iversen.

Kildemand passed Woffinden early in the final and kept him at arm’s length to secure GP podium from his third final as countrymen Iversen took a surprise win.
