goes a long way.
What is Naismith’s rule?
Allow 1 hour for every 5 km, plus 1 hour for every 600 m of ascent. It was devised by Scottish mountaineer William Naismith in 1892.
What about going down?
Gentle descents are a little quicker, but steep descents slow you down. We add 10 minutes for every 300 m of steep descent.
Is this calculator for me?
It suits most healthy adults. Results are estimates. If you have a heart condition, are pregnant or are new to exercise, check with your GP before increasing your activity.
