British
The British grading system for traditional climbs, used in Great Britain and Ireland, has (in theory) two parts: the adjectival grade and the technical grade. Sport climbing in Britain and Ireland uses the French grading system, often prefixed with the letter "F".
[edit] Adjectival grade
The adjectival grade attempts to assess the overall difficulty of the climb taking into account all factors, for a climber leading the route on sight in traditional style. In the early 20th century it ran Easy, Moderate, Difficult, but increasing standards have several times led to extra grades being added at the top. The adjectival grades are as follows:
* Easy (rarely used)
* Moderate (M, or "Mod")
* Difficult (D, or "Diff")
* Hard Difficult (HD - sometimes omitted)
* Very Difficult (VD, or "V Diff")
* Hard Very Difficult (HVD – sometimes omitted)
* Severe (S)
* Hard Severe (HS)
* Very Severe (VS)
* Hard Very Severe (HVS)
* Extremely Severe (E1, E2, E3, ...)
The Extremely Severe grade is subdivided in an open-ended fashion into E1 (easiest), E2, E3 and so on. As of 2006 the hardest climb was graded E11: Rhapsody on Dumbarton Rock, climbed by Dave MacLeod, featured French 8c+ climbing with the potential of a 20-metre fall onto a small wire. In 2008, James Pearson climbed The Walk of Life at Dyer's Lookout, North Devon; the ascent was performed without using bolts or pitons, with just mobile protections, and was graded E12/7a. In January 2009 the route was climbed by Dave MacLeod of Dumbarton fame, who downgraded the route to an E9 6c. Many climbers consider such high grades provisional, as the climbs have not yet been achieved on sight.
Some guidebooks make finer distinctions by adding the prefix "Mild"; thus, Mild Severe lies between Hard Very Difficult and Severe. Additionally, in some areas the grade "XS" is used for climbs on loose or crumbling rock, irrespective of their technical difficulty. |
