Reigning Easykart UK Cadet Champion James DeHavillande remained on course to make it two titles in two years with a stunning Junior class victory in the fourth round of the 2010 season at the Welsh circuit of Llandow.

DeHavillande, whose crash helmet design reflects his Welsh ancestry, proved to be a master of some typical Welsh summer weather as he dominated the dry but overcast pre-final and then repeated that triumph in the main final itself despite the arrival of rain mid way through the race.

With all karts on slick tyres, the Club 100 series organisers had no choice but to chequered flag the race several laps early before conditions became too dangerous but even in its truncated format DeHavillande still took the chequered flag with nearly three seconds to spare.

Fastest in timed qualifying and victorious in the heat DeHavillande needed some good fortune to win the pre-final when Luca Hirst retired on the last lap but having been gifted pole position for the main event DeHavillande led from start to finish, surviving a brief half spin coming out of Raymonds Hairpin on the penultimate lap as the rain intensified.

Despite winning two of the four rounds held so far in 2010 DeHavillande's points lead stands at a meagre two markers, largely thanks to a tenacious couple of drives from Thomas Grainger.

Grainger inherited second in the pre final thanks to Hirst's retirement and then chased DeHavillande hard in the final, pulling away from those behind but failing to make an impression on the winner. Grainger now sits two points behind DeHavillande with four rounds to go.

Toby Sowery passed James Lay in the early stages of the final to take third place, mirroring his position in the overall standings, twelve points clear of Lay and two more clear of fifth place driver Jamie Cummings, who could only finish eleventh in the final.

Hirst shrugged off the disappointment of his pre-final near miss with a storming drive to fifth from the back of the grid and had the race not been stopped several laps short he could well have made it onto the podium.

Grainger now has a month to think about how he can stop DeHavillande before round five of the series takes place at Whilton Mill in Northamptonshire in mid July.
