The marathon is two laps of a 21.1 km loop through the streets of Odense, starting on Stadionvej beside the sports park. The route is measured and approved by AIMS, and the organiser puts the gap between its highest and lowest points at 21 metres. Roads are closed to traffic for the race, and four large aid stations at about km 4, 8.5, 14 and 20 are passed twice. A checkpoint near km 20.5 decides whether you continue onto the second lap. Headphones, including open-ear types, are not allowed.
