The BritFours – The 400m Hills of Britain

The BritFours – The 400m Hills of Britain 

The concept of the BritFours was first explored in an article published on Mapping Mountains and in the RHSoc magazine in March 2018.  This concept has now materialised in to a published list hosted on Phil Newby’s website; Haroldstreet.

The BritFours comprise all British hills at or above 400m and below 500m in height that have 30m minimum drop.  There are 2051 qualifying hills in this list and its component parts are the 400m P30s of England, Isle of Man, Scotland and Wales, and there is no additional sub list.

Data for these lists were initially originated by the late E D ‘Clem’ Clements and Myrddyn Phillips, with the custodianship of Clem’s list now transferred to his Legacy Committee.  Their publication details are:

The 400m Hills of England, 400m Hills of Isle of Man and the 400m Hills of Wales were first listed by Myrddyn Phillips and published on the RHB file database in December 2002. 

E D ‘Clem’ Clements was first to list the Scottish 400m P30s; these were published in March 2008 and appeared as a part of the Marilyn Tops of Scotland spreadsheet in the RHB file database. 

It was these data that were collated by Mark Jackson for the 400m banding of Tumps published June 2009. 

The component parts to the BritFours have moved on since these lists first materialised 11 – 17 years ago.  Clem’s Scottish 400m list is now augmented into the Tumps, while the Welsh and English 400m lists are now co-authored with Aled Williams and have been re-named to Y Pedwarau – The 400m Hills of Wales and The Fours – The 400m Hills of England.  These developments have refined the lists in terms of numerical data and hill-name information.

The source lists for the BritFours are available on Haroldstreet, Mapping Mountains and the DoBIH.

BritFours – The 400m Hills of Britain – comprises all English, Manx, Scottish and Welsh hills 400m or more and below 500m in height that have 30m minimum drop and the list is available on Haroldstreet.
