The Bike and Run du Bol d'Air de Saint Avertin begins at the Domaine de Cangé, adjacent to the Château de Cangé on the Saint-Avertin heights in France's Centre-Val de Loire region. SAS Triathlon 37 organizes the weekend events, featuring Bike & Run races on Saturday afternoon, followed by a night run the same day. Sunday offers running, Nordic walking, hiking, and a family race. The schedule allows participants to select events based on age group or desired intensity, rather than a single format for all.
The Bike & Run component involves team entries and separates participants from very young children through juniors, alongside an XS Open race for wider involvement. Approximately 700 individuals are anticipated for the Bol d'Air nature-cross weekend, contributing to a local club festival atmosphere alongside the race meeting. The youth races are part of the FFTRI Centre-Val de Loire Youth Challenge, while the broader schedule accommodates families, club athletes, walkers, and runners seeking a winter activity on the Cangé estate.
