Hundreds of riders race from Belgium to Greece, with no set route, facing extreme heat and often on only a few hours sleep a night
The Transcontinental Race is an annual, self-supported bike race across Europe, founded by the long-distance cyclist Mike Hall in 2013. It covers about 3,500-4,000km (2,200 – 2,400 miles) and has started in Geraardsbergen, Belgium, for the last three years. Here, riders assemble, meet, compare kit and prepare for the race ahead. Participants are free to choose their own route between mandatory control points – a test as much of orienteering and route-planning as of physical and mental endurance.
