Coming down turns at 12 degrees
A gentle descent speeds you up: take off ten minutes for every 300 m down. A steep one does the opposite — you brake, you place your feet, and it adds those same ten minutes per 300 m. The line between them is an average slope of 12 degrees. That correction is Langmuir’s, laid on top of Naismith.

How to read this
- Going up: an hour per 5 km on the flat, plus an hour per 600 m of climb.
- Coming down assumes the same path back, adding or subtracting ten minutes per 300 m depending on the slope.
- Breaks are not included. Even five minutes an hour adds up to more than half an hour over a day.
- Total climb means every metre gained, including the ups after the downs. A map app will tell you.
