La Sale Caractère sends runners out at dusk through Josselin, a small city in Morbihan in Brittany. It is a 12 km semi-nocturnal urban trail and road race, with the option to run the whole distance solo or split it as a two-person relay.
The route uses illuminated streets and paths around the city, so the race is partly about running after dark and partly about seeing Josselin under lights. Around 620 runners line up, from beginners to more experienced racers, and Les Joyeux joggers josselinais organize the event with a festive, social feel.
