At what gradient does it become faster to walk than run uphill?

Around 40-50% gradient (climbing 1 metre vertically for every 2 metres forward), walking becomes faster than running. At these angles, trying to run is mechanically inefficient and exhausting, while a strong walking technique maintains better speed and conserves energy.

Why does my watch show such slow pace on steep fell climbs?

Your watch calculates horizontal distance, not vertical climb. On very steep sections where you might be gaining 1 metre of elevation for every 2-3 metres traveled forward, you could be moving at 600 metres per hour, which translates to something like 18 minutes per kilometre—but that doesn't account for the actual climbing effort involved.

How do you run up a really steep hill without exhausting yourself?

Use short steps, keep your weight over your feet, and use your hands on your knees or rocks for support. Accept that you'll walk or scramble the steepest bits—treat them as separate high-intensity efforts rather than trying to maintain even pace throughout.

The Fifty-Metre Climb That Takes Five Minutes: When Gradient Stops Making Sense

Fell running includes sections so steep you're essentially scrambling with your hands — where forward progress is measured in breaths per step, not pace. Why some ascents are faster walked, and why admitting it doesn't make you slower.
