Silverline Subaru BMR Racing's Colin Turkington still remains an outside threat for this seasons British Touring Car Championship crown after keeping himself in contention following an inspired charge to the Rockingham podium in race three.

The former double BTCC champion ended his Rockingham weekend by slicing his way from 15th to 3rd, scoring his eighth podium of the season, which has kept Turkington 48-points of championship leader Sam Tordoff.

Having struggled with the hard tyre during a trying second race, Turkington rose back up the order in race three at a ferocious rate after relentlessly picking his way through the pack to the rate of almost a car per lap.

At one point even Turkington thought the victory was on but the Subaru Levorg driver admitted 'using all of his trump cards' to get to third meant he was unable to make the difference during the last few laps.

"I was maximising everything I had from the start. I was trying to get out of the middle of the pack as quickly as I could because it's easy to get stuck there for the whole race. I was really leaning on the car but it was fast," said Turkington.

"As I got further to front it became more difficult to pass especially with the medium tyre runners. I was on the back of Gordon [Shedden] after the final safety car but he was also on the medium tyre.

"I used all my trump cards to get to third. I still had good pace but not enough to try and challenge for the win. When you come that far that you think 'wouldn't it be awesome to win' but I just didn't have enough left.

"I was coming through the pack so quickly and once I got up to third I thought I had a good chance. It would have probably Gordon and Aron [Smith] to have a bit of a ding dong for me to realistically win. I don't think Gordon had enough left to really attack."

While noting how open this seasons title fight has tended to be, Turkington admits his shot of handing Subaru the championship in their maiden BTCC season remains a slim one but insists it's never over until it's over.

"We're still very much on the outside 48 points back. We're still in the mix. I remember going to Brands Hatch leading by a similar margin and still wasn't sleeping that well so it's never over. It's more open this year than ever," Turkington concluded.

Moving ahead to Silverstone, Turkington will have to overcome the obstacle of starting the opening race from the rear of the grid after picking up a third reprimand at Rockingham.

Turkington received two penalties last weekend. The former for being adjudged to have overtaken Josh Cook with all four wheels over the white line - costing him a six-second penalty - while the latter came after passing Jake Hill under yellow flags in race three.
