Today, the V-Class is his mobile transition zone: In October he will be seeking revenge, says the 33-year old, as he sits in the boot of the V-Class and changes his sweaty jersey. The defeat in Hawaii motivates him during his training too. 'You need targets. You need to know why you're doing something,' says Kienle. The professional triathlete knows what he's talking about: In 2014, Kienle secured the title of IRONMAN World Champion at this classic contest in Hawaii. But before the much anticipated duel with the international competition, Kienle is anticipating a battle with himself first. Or put another way: The 33-year old is preparing himself for the world stage in the peace and quiet of his home. In Mühlacker, close to Pforzheim, Sebastian Kienle lives together with his wife in an apartment in his family home. He needs familiar surroundings, his family and sometimes peace and quiet, to get himself into shape mentally. Kienle parks the V-Class in the drive, heaves his racing bike swiftly out of the boot and disappears into the house.
