Pace [6] in minutes per kilometre or mile vs. slope angle resulting from Naismith's rule [7] for basal speeds of 5 and 4 km / h. [n 1]The original Naismith's rule from 1892 says that one should allow one hour per three miles on the map and an additional hour per 2000 feet of ascent.
Tobler's hiking function – walking speed vs. slope angle chart. Tobler's hiking function is an exponential function determining the hiking speed, taking into account the slope angle. [1] [2] [3] It was formulated by Waldo Tobler. This function was estimated from empirical data of Eduard Imhof. [4]
English: Walking velocity vs. slope angle resulting from Naismith's rule and Langmuir corrections for basal speeds of 5 and 4 km / h compared to Tobler's hiking function. Speed for the Naismith rule were calculated here for it's metrical version (5 kilometres horizontally and 600 meters of ascent), not the original one (3.1 mi and 2,000 ft).
A trailhead signage that shows the grade of a walking path at a park in Sydney, Australia.. A trail difficulty rating system, also known as walking track grading system, walk gradings or trail grades, is a classification system for trails or walking paths based on their relative technical and physical difficulty.

Commonly, individuals place some value on their time. Economic theory therefore predicts that value-of-time is a key factor influencing preferred walking speed.. Levine and Norenzayan (1999) measured preferred walking speeds of urban pedestrians in 31 countries and found that walking speed is positively correlated with the country's per capita GDP and purchasing power parity, as well as with a ...

Prior to its founding, four other hiking clubs had already been established in America. This included the very short-lived (first) Rocky Mountain Club in 1875, the White Mountain Club of Portland in 1873, the Alpine Club of Williamstown in 1863, and the Exploring Circle, which was established by four men from Lynn, Massachusetts in 1850.
