Anyone who has me on Facebook will know I completed a Z1 challenge solo in 3:13:30, here's a quick write-up on how it went...
I had decided on doing a Z1 that morning while commuting into Liverpool Street as I fancied my chances seeing as it wasn't a particularly busy day (in comparison to the weekend) so off I went. I made my decision as to where to start in a Subway just outside Aldgate station using the most professional of methods, closing my eyes, circling my finger and pointing at one station, and it came out with Victoria. I toyed with the idea of doing the Circle first but then changed my mind on the way down to the start and decided to chance taking out the south first and work from there. My final route with notes was as follows:
Victoria

Vauxhall

NR to Waterloo; not a bad change with 3m approx.

London Bridge

Elephant and Castle; I just about got on a southbound train as I hit the platform, had I failed to get this I would have had to wait TEN minutes!

Paddington (Bak)

Run to Paddington (H + C) where I had a 5m wait for a train to

Edgware Road

then a 0m change onto the Wimbleware to

Earl's Court

Aldgate East

Aldgate

Great Portland Street, where I had a 4m wait for a DB to

Euston Square

run to Warren Street

Goodge Street

Euston, where I didn't get lost unlike last time!

Bank, foolishly as I couldn't break the wall of bankers

NHG

another 0m change onto the Wimbleware back to

Earl's Court, where I missed a Piccadilly Line service because I forgot where the Starkey stairs were, meaning I had to wait an extra 2m for my final train to

Russell Square...
In retrospect I was extremely lucky to get two 0m changes on the Wimbleware, but to even do it twice was pretty stupid. Regardless not a bad time, and a pretty satisfied Rhys

I'm breaking through, I'm bending spoons.
