Hayley Williams proved size doesn't matter when she won the Production B grass track racing championship last month.

The Wallington speedster is the only driver who races a mini in a field largely consisting of Vauxhall Novas and Corsas but overcame that obstacle to win her first championship.

Grass track racing sees a field of up to 15 cars race 10 laps around a clay oval field at Tongham Motor Club in Alton and, despite her disadvantage, 25-year-old Williams triumphed over the rest of the field to win the championship, part of the South Eastern Grass Track Organisation, by 17 points.

It was also impressive because she was one of only two women in the field - with the other, Laura Chappell, finishing runner-up to her.

"It hasn't really sunk in yet that I have won," said Williams, who works in admin at construction company Russell Cawberry.

"I have come second in the Championship before but this is the first time I have won it and it is against mostly men too.

"It also shows how well have I done being the only mini - the Vauxhalls are naturally better.

"I definitely want to defend my title next year - I don't want to lose it now I have won it.

"I have got sponsors for this year that helped toward my car but we would like more for next year.

"We are also hoping to have five more cars in our group which would be more of a challenge, it is not as expensive as people think to race."

The Production B class features cars up with engines to 1300cc and racers have to start at different parts on the track depending on the points they have - with the leaders at the back of the field.

The races are non-contact and share similarities to stock car or hot rod racing and Williams credits her father John for getting her involved.

"My dad used to do a bit of oval racing and rally cross," she said.

"I used to go and watch him and then one day I said I wanted to do that.

"He thought it would be a phase and I would get bored of it after a while, but here we are 10 years later.

"There's lots I would like to do.

"My dad would like me to do rally cross which I am interested in but that ends up being a lot of money - the racing I am doing at the moment is probably the cheapest.

"I would like to do touring cars or something like that but I am probably too old."
