The New Year is a great time to reflect on the changes we want to or need to make. In last weeks assembly we had a time to reflect on this. One of the areas we looked was the “aggregation of marginal gains.” The presentation can be viewed here.

In 2010, Dave Brailsford faced a tough job. No British cyclist had ever won the Tour de France, but as the new General Manager and Performance Director for Team Sky (Great Britain’s professional cycling team), Brailsford was asked to change that. His approach was simple. Brailsford believed in a concept that he referred to as the “aggregation of marginal gains.” He explained it as “the 1% margin for improvement in everything you do.” His belief was that if you improved every area related to cycling by just 1%, then those small gains would add up to remarkable improvement.

They started by optimizing the things you might expect: the nutrition of riders, their weekly training program, the ergonomics of the bike seat, and the weight of the tyres. But Brailsford and his team didn’t stop there. They searched for 1% improvements in tiny areas that were overlooked by almost everyone else: discovering the pillow that offered the best sleep and taking it with them to hotels, testing for the most effective type of massage gel, and teaching riders the best way to wash their hands to avoid infection. They searched for 1% improvements everywhere.

Brailsford believed that if they could successfully execute this strategy, then Team Sky would be in a position to win the Tour de France in five years time. He was wrong. They won it in three years. In 2012, Team Sky rider Sir Bradley Wiggins became the first British cyclist to win the Tour de France. That same year, Brailsford coached the British cycling team at the 2012 Olympic Games and dominated the competition by winning 70% of the gold medals available.

In 2013, Team Sky repeated their feat by winning the Tour de France again, this time with rider Chris Froome. Many have referred to the British cycling feats in the Olympics and the Tour de France over the past 10 years as the most successful run in modern cycling history.

And now for the important question: what can we learn from Brailsford’s approach?

It’s so easy to overestimate the importance of one defining moment and underestimate the value of making better decisions on a daily basis. Almost every habit that you have — good or bad — is the result of many small decisions over time. And yet, how easily we forget this when we want to make a change. So often we convince ourselves that change is only meaningful if there is some large, visible outcome associated with it. Whether it is losing weight, building a business, traveling the world or any other goal, we often put pressure on ourselves to make some earth-shattering improvement that everyone will talk about. Meanwhile, improving by just 1% isn’t notable (and sometimes it isn’t even noticeable). But it can be just as meaningful, especially in the long run.
