Energy Kilometers Calculator Energy Kilometers Calculator Time and Energy is often more important than Distance You are out on a trek. It’s 9:30 am. The sign at the trail start says there is a great lake just 1.5 kilometres from the camp you are staying at. Easy enough for you and children in the group to do with you and be back at camp for lunch. No need to take food with. Right? It’s only 3 kilometres return. Even at a child’s pace that’s only 2 hours. Wrong… What the sign does not tell you is the lake is 300 meters higher than where you are now, and gaining altitude takes energy. As you gain altitude each 100 meters of ascent uses the same energy as walking between 1.5 to 2 kilometers depending on your walking speed. So that 300 meters ascent will equate to 4.5 to 6 kilometers extra “Energy kilometers”. Assuming the distance to the lake is 1.5 km each way, that makes it 3 km total, but now we add the energy kilometres needed for the altitude gain which is an additional 4.5 to 6 kilometres. (We only count the up hills) So now the trip to the lake is going to be a total of between 6 to 9 “Energy Kilometers”. Can you and the children do that before lunch without having substantial drinks and snacks along the way? A child walking at 1.5 kilometres an hour is now going to take between 4.5 and 6 hours. An adult will take 1.5 to 2.5 hours.

Naismiths Rule Calculator Naismiths Rule Calculator Naismith’s rule helps with the planning of a walking or hiking expedition by calculating how long it will take to travel the intended route, including any extra time taken when walking uphill. This rule of thumb was devised by William W. Naismith, a Scottish mountaineer, in 1892. A modern version can be formulated as follows: Allow one hour for every 3 miles (4.82 km) forward, plus an additional hour for every 2,000 feet (600 m) of ascent. The basic rule assumes hikers of reasonable fitness, on typical terrain, and under normal conditions. It does not account for delays, such as extended breaks for rest or sightseeing, or for navigational obstacles. (Wikipedia) Distance (Km) In Kilometers Altitude Gain (m) In Meters Estimated Walking Time Hours (Excluding Stops) (distance/4.82803)+(altitude/600) There have been many attempts and adapting this, and all have pro’s and con’s to them. In my personal; experience in the Drakensberg, mainly climbing to high altitude, I have found my own variation of the rule which works for me. My estimation works on the assumption of walking at 2km/h. Alternate Estimated Variation Hours (Excluding Stops) (distance/2)+(altitude/600) Try setting your own walking speed.
