How far from the land would you be to do that distance Link to comment Share on other sites More sharing options...

That is the actual coastline length following every inlet and promentary, and going around each island (Anglesey, IoM, Skye, etc etc) Link to comment Share on other sites More sharing options...

My walking "SatMap" GPS is set up using OS mapping at 1:25,000 or 1:50,000 and displays distance and heights in Imperial ( feet / yards / miles) (other settings are available) Old picture: Walked 5.29 miles 45 feet from my start position Average moving speed 3.4mph Current elevation 29 feet ASL Total ascent gain 49 feet. Maximum height achieved 55 feet ASL Minimum height achieved 22 feet ASL Edited March 4, 2021 by Alan de Enfield Link to comment Share on other sites More sharing options...

The last imperial scale OS maps were published in the 1970s The Ordnance Survey's large-scale mapping comprises 1:2,500 maps for urban areas and 1:10,000 more generally. (The latter superseded the 1:10,560 "six inches to the mile" scale in the 1950s In fact the use of metric scale mapping in the UK dates back to 1911 which is probably before you were born. .
