Britain’s Cycling Superheroes: What Price Success?

Sir Dave Brailsford and other insiders tell the story of the extraordinary triumphs and recent controversies that have rocked Britain’s cycling medal factory.

Brailsford and Shane Sutton are considered the two chief architects behind Britain’s cycling dominance at both the Olympics and the Tour de France.

Both men are driven by a huge hunger to win and dominate their rivals. This relentless desire to beat their opponents led them to create the greatest medal-winning factory in British sporting history. Yet both men have suffered criticism for the way they ran British Cycling – Sutton resigned amid claims of sexism and discrimination towards elite cyclists – and questions have been raised about a medical exemption which allowed Sir Bradley Wiggins to take a corticosteroid during the Tour de France.

With exclusive interviews and access they now tell their story: how they built a winning machine on the track and at the Tour, and how they respond to those who criticise their regimes.
