If you can't manage to stay awake for the duration of a Grand Prix, then you don't stand a chance with the Le Mans 24 Hours, a hardcore endurance race lasting - funnily enough - 24 hours.
But if you reckon you're up to the challenge, then keep reading. TopGear.com has teamed up with Shell V-Power Diesel to offer you and a friend the chance to win two VIP entrance tickets to the 2007 Le Mans race, including travel, accommodation for one night with food and gift packs all thrown in.
Shell V-Power Diesel race fuel powered the Audi R10 - the world's first diesel-powered car - to first place in last year's Le Mans race and they hope to again celebrate powering a diesel car to victory by offering this opportunity to win this unique Shell V-Power Diesel package.
After 27 pit stops in over 24 hours, last year the winning car completed a record breaking 380 laps to secure an unforgettable victory - one lap more than the previous record set in 2004.
As the official fuel supplier of the 2007 Le Mans, Shell will supply approximately 260,000 litres of Shell V-Power M24 and Shell V-Power Diesel LM24.
So if you think you're hard enough to endure 24 hours of racing, make sure you keep the weekend of June 16 and 17 free or you'll be kicking yourself for a very long time.
