Bike and Run de Blois is a two-person Bike & Run event held in Blois, located in the Loir-et-Cher department of Centre-Val de Loire. Each pair shares a single bicycle, with one partner cycling while the other runs; they may exchange the bike at any point. The race is scheduled for October and includes youth, XS, and S formats. Generation Triathlon Blois is the organizing body.
The shortest courses are designed for young children, and the longest routes extend to approximately 12 km. Consequently, the event accommodates participants from the mini poussin categories up to masters. The straightforward rule provides the race with its strategic depth: teams must balance their pace, bike exchanges, and endurance, ensuring both members finish together. The stated distances are 3 km, 5 km, 6 km, and 12 km, although some event details indicate the full range as 1.6 km to 12.4 km.
