Bike Racing as Chess: The Game Theory Behind Tour de France Breakaways

The Tour de France is not only a test of fitness but a study in game theory, where riders frequently join breakaways to maximize sponsor exposure and team benefits even when the odds of winning the stage are slim. Air resistance makes large pelotons efficient, so cooperation is the norm; breakaways succeed far more on mountain stages than flat ones, but as stages near the finish, riders revert to self-interest, turning breaks into a 'tragedy of the commons.' This blend of incentives and physics is why cycling is dubbed 'chess on wheels.'
