Cycling and Man United coach Sir Dave Brailsford on marginal gains, the CORE philosophy, motivation, and what relentless success really costs.

Sir Dave Brailsford — Director of Sport at Manchester United, legendary cycling coach who led British Cycling and Team Sky to dominance using his 'marginal gains' philosophy.
Sir Dave Brailsford traces his path from a Welsh-speaking childhood and a single-ticket gamble to chase pro cycling in France, through sports science, an MBA, and into British Olympic and Team Sky success. He breaks down his coaching frameworks: the CORE philosophy (Commitment, Ownership, Responsibility, personal Excellence) developed with psychiatrist Steve Peters, and marginal gains, the idea that small compounding improvements beat chasing perfection. He explains separating dreams from controllable targets, judging individuals' intrinsic motivation, and making values-anchored decisions under emotional pressure. He also reflects candidly on the cost of obsession, his cancer and heart surgery scares, and his evolving belief that how a team wins (style, emotion) matters as much as winning itself.
