I learnt a lot, such as how unfit I am and how annoying it is to miss the Harrow run, along with how useless my memory is in remembering to get witness statements at the right time or recording departure/arrival times in the log. I also gained invaluable info on runs and good ideas/bad ideas with routes and connections.
The day itself was a day of negligable 'great' changes (basically only Wimbledon-Morden and Mill Hill East), plenty of mediocre changes and a few too many poor changes. The Piccadilly line problems at the end of the day were our only network issues, however, and gave us the interesting situation of our train changing destination twice during the journey (initally T5, then Northfields, then Rayners Lane!).
Although I was prepared for this being my one and only attempt, I now feel I have to use the knowledge I have gained to try again and try and beat it, my only problem being that Ollie has now retired, so I will need someone else (or more) to run with. I doubt this will be until Spring, however, when the temperature and other conditions will be more favourable.
Thanks also to Antony for organising everything.
P.S. As an aside, the taxi driver from Terminal 5 to the Travelodge nearby said he should be charging me £55 for the journey as it went outside the Metropolitan Police area!
For those who don't know, the hotel is all of 2 miles away, surely the most expensive taxi ever?! In the end I negotiated the 'bargain' rate of only £20. Not in much position to argue at gone midnight, however
