Got to love Bedford during this hot weather. Or more specifically wearing full racing overalls and a helmet, being strapped into a small compartment attached to a very hot thing and driving very fast round black tarmac at Bedford Autodrome.

Whoooohooo - what a day! Got to drive the Caterham 7, Evo VI, Vauxhall VX220 turbo, Jaguar JP1, Renaultsport Clio, go-karts, offroady things and a (slightly) restricted Formula Palmer Audi single seater!

I have never got so dehydrated in my life, although I was drinking stacks of water at every break. Some of those cars are just toasty, though - the Caterhams, especially, with their wonderful foot-warming thin aluminium bulkheads.

I never realised how good the VX220 was. Calling it a Vauxhall gives you the wrong impression. It should be called a Lotus
