In 2003 Dave Brailsford initiated changes in British cycling that dramatically transformed British cycling on the world stage. Read this excellent summary by behavior change expert James Clear, author of Atomic Habits.
In short, Brailsford started a path of improving the team by 1% in every conceivable aspect of their training in an approach he called the “Aggregation of Marginal Gains”. The result was transforming a team that was largely the laughing stock of the cycling world into a team that won 60% of the gold medals in the road and track cycling events at the 2008 Olympic Games. In 2012 they set nine Olympic records and seven world records. Members of this team went on to win the Tour de France 5 out of 6 years from 2012 to 2017.
Is it possible that you could achieve a similar transformation in your life by making some small changes in some key areas of your life?
