Climbing with ESI

Climbing is a physical and sports practice which consists in carrying out a quadrupedal movement (mainly using hands and feet), on a more or less vertical plane (slab, overhang, overhang...), on a natural support (rock) in a generally unknown and uncertain environment (varied and variable) with the objective of reaching a previously fixed goal, and this in "complete safety". 

Climbing routes are graded to allow climbers to "find their way" (safety, efficiency).

The most common current rating is

3 / 3+ / 4 / 4+ / 5A / 5B / 5C / 6A / 6B / 6C /7A / 7B / 7C / 8A / 8B / 8C / 9A / 9B

(With intermediate degrees: example 6B- / 6B / 6B+)
