The 20-Mile March
Achieve greatness through consistent daily progress regardless of conditions
The 20-Mile March is Collins's concept of achieving a consistent performance marker every day regardless of conditions — good or bad. Named after Roald Amundsen's approach to reaching the South Pole, where his team marched exactly 20 miles per day regardless of weather while Robert Scott's team pushed hard in good weather and stopped in bad weather, eventually perishing. The principle is that you set both a lower bound (minimum progress that must be made even on terrible days) and an upper bound (maximum progress even on great days to prevent burnout and overextension). This dual-bound discipline produces dramatically better long-term results than reactive approaches that swing between intense effort and no effort. The march creates compounding consistency that is nearly impossible to beat over extended time horizons.
- Consistency over time beats intensity in bursts for long-term achievement
- Both a lower bound and an upper bound on daily effort prevent burnout and maintain momentum
- Self-imposed constraints during good times are as important as discipline during hard times
- The march must be calibrated to be achievable in the worst conditions and restraining in the best
- Define Your March MetricsIdentify one to three key performance indicators that represent meaningful daily or weekly progress toward your most important goals. These must be within your control — not outcomes dependent on external factors. Then set both a lower bound (the minimum you will achieve even on your worst day) and an upper bound (the maximum you will do even on your best day). The lower bound should be achievable even when sick, tired, or dealing with crises. The upper bound prevents overextension that leads to burnout or inconsistency.Pro tipSet your lower bound at roughly 70% of your comfortable daily capacity and your upper bound at 120% — this creates a sustainable rangeWarningSetting the lower bound too high will cause you to miss it on bad days, destroying the consistency that makes the march effective
- March Every Day Regardless of ConditionsExecute your march consistently regardless of external circumstances, motivation levels, or mood. On days when everything is going well and you feel unstoppable, march your amount and stop — use remaining energy for recovery, reflection, or preparation. On days when conditions are terrible and every part of you wants to stop, march your minimum amount. The discipline of showing up on bad days is where the compound advantage builds, and the discipline of stopping on good days is what prevents the burnout that derails long-term performance.Pro tipTrack your march completion rate visually — a chain of completed days creates powerful motivational momentum
- Review and Recalibrate QuarterlyEvery three months, review your march data. Are you consistently hitting your lower bound? If not, it may be set too high. Are you frequently bumping against your upper bound and wanting more? Your capacity may have increased, and you can carefully raise both bounds. The march is not static — as you build capacity through consistent practice, your daily range should gradually increase. But increase slowly and deliberately, never dramatically. A 10% increase per quarter is aggressive enough to compound significantly over years.Pro tipKeep your march range stable for at least two full quarters before adjusting upward — premature increases are a common failure modeWarningAvoid the temptation to raise bounds after one great month — consistency is the whole point
Amundsen committed his team to marching 15-20 miles per day regardless of Antarctic conditions. When weather was perfect and the team wanted to push 30 miles, he forced them to stop and rest. When blizzards raged and visibility was near zero, he forced them to march their minimum. His competitor Robert Scott pushed hard in good weather and stopped in bad weather, creating wildly inconsistent progress.
Collins drew this concept from the parallel expeditions to the South Pole in 1911. Amundsen committed to marching 15-20 miles per day regardless of conditions. When the weather was beautiful and his team wanted to push further, he made them stop and rest. When blizzards raged and they wanted to stay in tents, he made them march their minimum distance. Scott, by contrast, pushed his team to exhaustion in good weather and retreated in bad weather. Amundsen reached the pole and returned safely; Scott's entire party perished. Collins applied this principle to his 10X research, finding that companies that maintained consistent progress markers dramatically outperformed those with volatile effort patterns.
