Triathlon du Nouvel An is a short New Year triathlon held in Avion, Pas-de-Calais, Hauts-de-France. It typically takes place in mid-January, making its name literal: a cold-weather swim-bike-run to begin the year. The format is XS distance, featuring a 400 m swim, a 14 km road-bike leg, and a 5 km road run, totaling 19.4 km.
The event is described as a nature and forest triathlon, positioning it as a compact outdoor challenge rather than a large urban race. Its slogan is “Swim, ride, run...and happy new year!”, reflecting the straightforward concept: to shed the holiday season with a manageable yet brisk multi-sport effort. The race organizers suggest nearby Hauts-de-France destinations like Vimy, Lens, Arras, and Lille for visitors after the event.
