Detour de France offers a fascinating look inside the world's biggest annual sporting event. The film focuses on three Australians reporting on the world famous cycling event. All three bring a larrikin humour to their antics, which propels the film from mere reportage to something more akin to attending a sporting event with 'the boys'.
