The 15K2 is a running race scheduled for early April in Parthenay, a town in the Deux-Sevres department of western France. It is organized by TCG 79, the Triathlon club de Gatine, also known as the Parthenay triathlon club.
The race follows a route through the streets of Parthenay and is presented locally as a new, playful format instead of a standard road race. Boris Dessenoix, the club's vice-president and a former high-level triathlete, notes an increase in runners as the sport gains popularity in France because of its ease of entry and accessibility.
