When Simon Warren first published his “100 Greatest Cycling Climbs” back in 2010, he probably never dreamt that it would spawn a whole series of guide books about climbing hills on a bike. He’s now the author of twelve separate publications which cover all the regions of the UK as well as Belgium and famous climbs of the Tour de France.

He was appearing at the Chiltern 100 Cycling Festival last month where he was signing books and chatting affably to all and sundry.
