Never seen a shower at Victoria station but never really looked.
cant think of a pool round there but there is the Kings College London gym near Waterloo. £6 for a. External person to use gym. If you ask May do a deal of just using shower. Would post link but struggling to do it on iPad!
Not sure if you want feedback, but I had one quick point about q10. You ask "how often do you tell friends and family your I tended route and when you'll be back" to my mind these are two very different things. I always tell my boyfriend when I'll be back, but never tell him my route. I answered never of the survey as I never do both.
This year we went swimming instead (well sort of... the pool was too busy to really swim!) But my mum, sister and I have been on a family run before for christmas.
If I'm with my boyfriend's family, they're usually busy and do the a big family christmas. It does make it difficult to fit in a run, but I usually do on either on Christmas eve or Boxing day (or both).
