Marginal Gains: How Small Improvements Drive Extraordinary Results

When Sir Dave Brailsford transformed British Cycling, he didn’t focus on sweeping changes. Instead, he looked for tiny areas to improve by just 1% — from bike mechanics to sleep quality, even the massage gel athletes used.

Individually, these gains seemed insignificant. But together, they created a competitive edge so powerful it produced multiple Tour de France wins and Olympic dominance.

This is the philosophy of marginal gains: the idea that consistent, small improvements add up to extraordinary results.

It echoes the Butterfly Effect, which shows how even the smallest action — a flap of wings, a single decision, a micro-change — can ripple outwards to cause significant transformation. In sport, business, and leadership, both principles remind us: big outcomes are the product of small, deliberate actions.

Marginal gains isn’t just about sport — it’s a framework any organisation can adopt.

• Sales teams can improve by streamlining calls, tweaking pitches, or improving follow-ups.
• Leaders can strengthen performance by making 1% shifts in communication, culture, or decision-making.
• Individuals can build resilience and habits by focusing on consistent micro-improvements.

Like the Butterfly Effect, these shifts may feel small in the moment, but their cumulative impact is transformational.

Businesses that focus only on bold moves risk overlooking the incremental improvements that make sustainable success possible. Marginal gains teaches leaders to:

1. Value progress over perfection.
2. Embed learning into culture.
3. Celebrate small wins as steps towards transformation.
4. Reduce risk by testing and refining.

The Butterfly Effect reminds us that no action is too small to matter. The philosophy of marginal gains shows us how to harness that truth systematically.

There is a wealth of marginal gains speakers on the UK and global circuit who bring this philosophy to life:

• Dame Kelly Holmes – Double Olympic champion whose career was defined by consistent training and marginal improvements that led to gold in Athens. She now speaks about resilience, performance, and building winning habits.
• Jamil Qureshi – One of the most in-demand performance psychologists, Jamil has worked with world-class athletes, astronauts, and business leaders. He shows how mindset shifts and marginal improvements drive elite performance.
• James Clear – Author of the global bestseller Atomic Habits. Clear explains how 1% daily improvements compound into remarkable personal and organisational transformation.
• Sir Clive Woodward – England’s Rugby World Cup-winning coach, famous for introducing innovations and marginal gains strategies that turned a good team into champions.
• Damian Hughes – Organisational psychologist and author of The Barcelona Way. He unpacks how high-performing cultures thrive by embedding marginal gains into everyday routines.
• Leanne Spencer – Keynote speaker and wellbeing advocate who specialises in sustainable performance. She shows how small lifestyle and wellbeing changes fuel resilience and long-term success at work.

Here are five actionable steps inspired by both principles:

1. Audit the small stuff. Like Brailsford did with British Cycling, find overlooked areas to improve.
2. Break down big goals. Debra Searle’s Atlantic crossing was completed one stroke at a time.
3. Recognise ripple effects. Martine Wright’s journey shows how small acts of resilience inspire widespread change.
4. Build feedback loops. Encourage reflection and refinement in teams, like Matthew Syed’s Black Box Thinking.
5. Keep consistency. The power of marginal gains comes from sustained effort, compounding into transformation.
