His enthusiasm for cycling is shared by many German Christians. In St Catherine’s, one of Hamburg’s principal Lutheran churches, the pastor invites cyclists to bring their means of transport into the church, while down in Bavaria Christians use their bicycles to go on pilgrimages. There’s even a cycling cantor: Martin Schulze, who rides from one parish to another to play the organ. With no fewer than 350 cycle routes across the country, German cycling enthusiasts are spoilt for choice.
