Congratulations to Neil who has just completed his walk of all London Underground Tube Lines. It took him 54 days (not continuously) duing a period of six months to walk 378.5 miles to walk between all the stations on all the Tube lines of London.
He started the project last December and said "As I walk I'm recording my tracks with a GPS data logger and taking lots of photos. The walking routes and pics are on the site. London Photo Project - Tube Walking Blog - I'm expecting to have finished all 12 lines (I started when the East London line was still running) before the end of June."
He correctly (I think) guesses that he may be the only person to have done this, specially as he started before the East London Line was closed. It's similar to a number of other projects that try to show the how long it might take to walk between Tube stations and whether it's healthier or faster to walk, than take the London Underground.
But to walk all 378.5 miles and map your route taking photos along the way is a great achievement. Well done Neil and I wonder if you have set a challenge for someone to do the same. Sadly, they'll have to wait until the East London Line re-opens though.
