S4 Mullerthal X-treme

The name of the route starting in Echternach comes from the numerous uphill and downhill sections that make the route extremely difficult but also interesting. Over 100 km, nearly 2,000 meters of altitude must be overcome, which corresponds to almost 200 meters of ascent every 10 km on average. The intense and compact climbs also make this route extremely demanding. In total, eight more or less difficult climbs must be mastered. The steepest climb with a temporary 16% gradient is at kilometer 73 and leads from the Sauertal in Born up to Boursdorf. This route is definitely recommended only for very fit cyclists.
