Kate booked the high-speed ride on a rubber “doughnut” for him weeks ago, expecting the weather to be summery. The Prince, who turned 30 last Thursday, insisted on going ahead with it despite downpours and bitter winds sweeping Anglesey, North Wales.
After William dried himself off, the party retired to their tiny rented cottage on the island for a home-cooked supper and drinks. A source said: “For most 30-year-olds who have just inherited £10million, the last thing they would want to do is freeze themselves on a wet weekend in Wales. But this is typical of William.”
The 12-strong party included William’s life-long pals Thomas van Straubenzee, Harry Aubrey-Fletcher and David Jardine Paterson.
