This is a list of P600 mountains in Britain and Ireland by height. A P600 is defined as a mountain with a topographic prominence above 600 m (1,969 ft), regardless of elevation or any other merits (e.g. topographic isolation); this is a similar approach to that of the Marilyn, Simms, HuMP and TuMP British Isle mountain and hill classifications. By definition, P600s have a height above 600 m (1,969 ft), the requirement to be called a "mountain" in the British Isles. The "P" terminology is an international classification,[1][2] along with P1500 Ultras.[3][4] P600 and "Majors" are used interchangeably.[5][6][7]
As of October 2018[update], there were 120 P600s in the British Isles: 81 in Scotland, 25 in Ireland, 8 in Wales, 4 in England, 1 in Northern Ireland, and 1 in the Isle of Man. The 120 P600s contained 54 of the 282 Scottish Munros, and 10 of the 34 Non-Scottish Munros (or Furths), all of which have heights above 3,000 feet (914.4 m), and are sometimes called the "Super-Majors". The list also contained the highest mountains in Scotland, Wales, Ireland, and England.
On 9 November 2019, Norfolk climber Liam Chase became the first person to complete all 120 P600s in a single calendar year, starting with Cross Fell on 1 January, and ending with Pen y Fan.[8] Chase was also only the seventh person recorded to have climbed all P600s over any time period.[8][9]
Major: peaks with a minimum prominence of 600m. I believe the term was also coined by [American mountaineer] Steve Fry. There are 95 in Britain. Hall of Fame entry minimum is 150. [..] P600s are more the domain of continent dwellers.
In Britain the main thresholds for relative height (prominence) listings are 150m, 100m and 30m. Worldwide the thresholds for prominence are larger, typically 1500m, 600m and 150m. These may be referred to as Ultras or P1500s, Majors or P600s and Marilyns or P150s.
An early U.S. led initiative was to list hills worldwide with a drop of at least 2000ft (609.6m). Although a register of baggers' totals is maintained by Andy Martin, the prominence criterion has been superseded by 600m or 500m in countries outside the US. Hills having a drop of at least 600m or 500m can be obtained by a search on drop, or by a sort in the Excel version, and both lists are offered on Hill Bagging. Internationally, 1500m drop has become the accepted standard for the most prominent mountains and the category is known as the Ultras.
There have been numerous hill lists produced since this book was first published in 1992. Some have found their way into print, others are available online in a central database or as separate downloadable files. This brief bibliography concentrates on the more important lists and sources that are now readily available for those interested. The glossary below may assist in understanding the titles and content of some references.
A list of British and Irish hills with at least 600m of prominence, also known as the Major Mountains of Britain & Ireland. There are also 25 hills located in Ireland with 600m prominence. These are not displayed on the above map as OS maps do not cover Ireland.
The map and list depict the P600m Peaks - a list of British and Irish hills with at least 600m of prominence, also known as the Major Mountains of Britain & Ireland. One of the hills, Rois-Bheinn, could be substituted by Beinn Odhar Bheag - both have a height of 882m, so you could assign to either the 774m prominence and both should be climbed.
