I'm going to walk the 14 mile route of the circle line, starting from Victoria Station at 10am and heading east, so anti-clockwise around the route. It's not a race - regular stops to drink, eat or just check out the scenery.

*UPDATE*

check out my blog

for a downloadable PDF containing full route and timings for Sunday.

And here are the key meeting points:
VICTORIA STATION (outside main entrance) 10am
MONUMENT STATION (outside main entrance I guess) 11.30am
LIVERPOOL STREET STATION (outside Bishopsgate entrance) 12.20pm
FARRINGDON STATION (lunchbreak) 1.05pm
KINGS CROSS STATION (outside main entrance, I’ll be coming from Grays Inn Rd) 2pm
PADDINGTON 3.05pm
SOUTH KENSINGTON STATION (tea break) 4.30pm
back at VICTORIA by 5.30pm

You're welcome to come with me for some or all of it - I'll publish an estimate of where we'll be and when nearer the time.

By the way, this will take place whatever the weather.

Don't worry, I'm not expecting hundreds to be up for it on an autumnal Sunday but if a few come for bits, it'll be superb.

Feel free to invite your friends as well.
