Small improvements can add up to a significant gain

The Team GB cycling team was a huge success in last summer’s Olympics.

Chris Hoy, Victoria Pendleton, Emma Trott and the rest of the team became national heroes.

One of the possible reasons for their success, which caused the French to believe the team was equipped with ‘magic wheels’, is attributed to Matt Parker, appointed ‘Head of Marginal Gains’ by the main coach, Dave Brailsford.
