At eighty-one years of age, Alan Bonner is a lifelong Tour de France fan and over the past few years has become an equally avid Team Sky fan. He regularly clocks up 80-100 miles of cycling each week and is an ardent hill climber. Since retiring, he's ridden up some of the most notoriously difficult mountains in previous Tour de France races, including the Alpe d'Huez and Mont Ventoux -- all on his Paris Tour de France racing bike, bought in Stoke Newington, London in 1949. With roughly 40-50 thousand miles already covered by this elegant 65 year old steed, we join Alan as he attempts to emulate the actions of the Team Sky riders by tackling one of the Tour de France's toughest climbs in Yorkshire: Buttertubs Pass.
