Nigel Mansell Le Mans debut 2010

Nigel Mansell & Sons - Le Mans entrants 2010 Nigel Mansell is still one of our best known racing drivers, despite it being more than a year or two since he hung up his F1 helmet. But that hasn’t stopped him enjoying time behind the wheel of a fast motor or two and guiding the motor racing careers of his sons, Leo and Greg. Last year, perhaps a little tongue in cheek whilst being interviewed by Radio 2 jock and Ferrari nut Chris Evans, Nigel expressed a desire to get back in to F1 and said he could “…jump in a Ferrari [F1] tomorrow and be competitive.” But going backwards is not usually a sensible route – as Michael Schumacher can currently testify - but new challenges – whatever your age – are to be relished.

They left the staging area at 1 in the morning. The Manxter Dual Sport dune buggy was holding by faith alone -- it had been repaired over and over again, parts tied or taped together, seldom replaced; covered in the acrid dust of the desert, a dust that fills your lungs and face, a dust that worms its way into the cabin and across every surface. The GPS navigation was out.
