A total of 14 celebrities are currently primed to take on the Silverstone Grand Prix track, raising money for the Bobby Moore Fund for Cancer Research UK in the Celebrity Challenge at this weekend's Silverstone Classic.

Latest to gain their race licenses and join the grid for the weekend are Sky Sports presenter Vicky Gomersall and BBC Radio's Sally 'Traffic' Boazman.

“It's going to be a real challenge to drive around Silverstone for 20 minutes and not make a complete pig's ear of it, which I probably will do!” said Boazman. “But as I keep saying to everyone, if you come along and watch at least you'll have a good laugh. I hope that us girlies will outdo the boys – we'll certainly give it a good go.”

The pair join organics entrepreneur Jo Wood and model Zoe Cole as females on the grid of race-prepared Morgan Roadsters.

The quartet will face tough competition from the male contingent that includes Heston Blumenthal, past winner of The Apprentice Lee McQueen, The Feeling drummer Paul Stewart and dancer Brendan Cole – who also happens to be Zoe's husband. Last year's winner Rick Parfitt Jr also returns to defend his crown.

“I hear that Rick Parfitt Jr won the race last year – well he needs to step aside because there's a new champion in town!” laughed Gomersall. “Basically, I just want the women to win. It won't be easy, though, and it could be a bit scary. In fact, I think this is probably the scariest thing I have ever done. I've jumped out of a plane before, but this is going to be right up there.”

Last year's race raised £25,000 and the celebrity racers are aiming to beat that mark this year.

Stephanie Moore MBE, Bobby's widow and fund founder, says: “I'm really looking forward to the Silverstone Classic Celebrity Challenge which I'm sure will be a fantastic occasion. The celebrity drivers have been doing a marvellous job with their fundraising so far. I'm extremely grateful for all their efforts and wish everybody the best of luck for the race.”
