For any new forumites or people with short memories, the idea is to visit 15 randomly selected stations in Zones 1 and 2 in the fastest time - but with a catch that only the starting station is revealed in advance: all other stations are only revealed when the timer starts.
It's been suggested to do this in half-term week as some of the youngsters would like to get humiliated for themselves, and who am I to stand in their way?

I've checked my calendar and in fact I'm in London with work Tues-Weds-Thurs that week, so I'd like to propose going for Weds 24th Oct. I will use the program I wrote previously to generate the stations, and will likely announce the starting station on the Sunday evening. However there is a chance of this taking slightly longer than a Z1 challenge - although it could be much less if the stations chosen work well together unlike last time - so I'd like to go for a 6:45 meet-up at the chosen station.
Please post here if you are free and interested, also if the day after could work better for you as it could conceivably be changed to the Thursday if there is demand. Also if anyone has a sofa or spare room free for the Weds night so I don't have to slink back off to Milton Keynes after finishing, it would be gratefully welcomed.
I'm off to get busy not planning a route - hopefully see you on the 24th
