Phil Burt is the physio behind a generation of British Olympic gold medals and Tour de France wins. As Lead Physiotherapist at British Cycling and bike-fit lead at Team Sky during their dominant decade, he is the person riders went to when a knee, back, or saddle issue threatened a season. His Bike Fit book turned that clinical work into a manual that amateur fitters now use as a reference. For riders chasing a few more durable watts without injury, his approach — anchor the saddle, then the cleat, then the cockpit, and never optimise aero at the expense of physiology — is the modern gold standard.
