Karlsruhe is mad about bicycles. In the summer months, a digital wheel counter registered up to 200,000 cyclists a month in the city centre. Bicycles are every bit as commonplace here as rickshaws are in Mumbai. A new NaturRadtour cycling nature tour will soon join all of the city’s protected areas together in a 48-kilometre green route. For fitness enthusiasts who like more of a challenge, the Turmberg-omat – Turmberg being Karlsruhe’s local mountain – will put those muscles through their paces. To reach the top of the Turmberg, cyclists must brave a route measuring 1.8 kilometres in length and 120 metres in height with a maximum ascent of 13%. Their finishing time is measured with a time card. The best cyclists can get to the top in under 5 minutes. How about you?
