Margin is a magazine about performance in sport.
We publish writing on how performance is built, expressed, and sometimes undone. Our focus is on preparation, decision-making, context, and time.
While our roots are in endurance sport, our interests extend more broadly. We are drawn to the systems, habits, environments, and choices that shape success long before results are visible.
What we cover
Margin looks at performance across the full cycle.
Preparation
Training philosophy, nutrition, recovery, equipment, culture, and the long-term decisions that shape readiness for individuals and teams.
Expression
Competition, tactics, pacing, and performance under pressure. Why events unfold the way they do.
Aftermath
Fatigue, adaptation, injury, confidence, decline, and what performance leaves behind once competition is over.
Our work is grounded in real events, lived experience, and historical context. We are as interested in how successful athletes and teams are built as we are in how races are won. We also look back, examining past eras, equipment, innovations, and ideas that continue to influence performance today.
How we work
Margin is selective by design.
All pieces begin as pitches. We publish fewer articles than most sports sites and take time choosing what to run. Insight matters more than speed. Clarity matters more than volume.
We treat performance as a system shaped by decisions, constraints, environments, and time—not just talent or effort.
Who it's for
Margin is for readers who care deeply about sport and want to understand how performance actually works.
If you are interested in preparation as much as outcomes, in what makes athletes and teams successful over time, and in how small margins shape results across eras, you are in the right place.
