The Green Duathlon de la Noix guides runners and cyclists across the walnut plains of Tullins, a town in Isère within the Auvergne-Rhône-Alpes region. This run-bike-run duathlon takes place near the end of March, offering XS and S distances suitable for both casual participants and competitive club racers. The entire course is traffic-free, a significant feature as the route crosses active walnut farmland instead of a city park. The event holds a Green Duathlon designation, emphasizing an environmentally conscious approach where nature is an integral part of the setting.
T.I.GRE., the local triathlon club, established the race following their organization of a major international triathlon and paratriathlon. Tullins is hosting this duathlon for its second occurrence. The main race also functions as the South-East half-final for Division 3 clubs in the French Duathlon Championship, drawing over 200 of the region's top duathletes seeking qualification. Complementing this competitive field, the weekend features two open duathlons and a complimentary children's duathlon, accommodating club athletes, amateurs, and families. Initial participants commended the safe, traffic-free routes and the club's blend of professional organization and lively race-day ambiance.
