Heroes, Villains and Velodromes: Chris Hoy and Britain's Track Cycling Revolution by Richard Moore. Interesting book and has excellent insight into British racing, lottery funding, Brailsford and of course Chris Hoy. There is overlap with Hoy's autobiography.
Any big takeaways?
The Brits are very serious about their cycling as evidenced by having a full time psychiatrist on the management team.
The drug discussion was interesting as it related to...can a clean athlete win at the highest levels of competition?
Details and technology matter.
