I love horsepower and have worked in Formula One for 20 years. But this little adventure isn't about the latest McLaren or Ferrari; it's about one solitary prancing horse.

On 05 March I'm competing in a charity race at Newbury, on a horse kindly lent to me by trainer Kim Bailey. The aim is to fulfill a dream and, more importantly, to raise money for Greatwood - a charity that cares for ex-race horses and uses them to help educate disadvantaged children.

Please join me on this exciting journey - and dig deep!
