The expression "end to end" in the UK invariably registers with people as travelling from Land's End to John O'Groats - from the far south-west to the far north-east of the mainland British Isles.
The purist will tell you (normally spluttering through his beard and spilling real ale on his sandals) that the REAL end-to-end is actually from Lizard Point to Dunnett Head ... whatever, the rides listed and the content of the website relate to the "principle of an end-to-end"
As well as the LEJOG & JOGLE in the UK rides the site will carry information about other end-to-end cycle journeys be that from Malin to Mizen in Ireland, wherever they start from in Northern Norway and Gibraltar, Alaska to Tierra del Fuego - or the Calais to Montpellier that the webmaster rode in 2008 .... just send the reports!
