Not bad timewise considering:
4 stages by foot, which were done at normal walking pace, which resulted in missing one connection by about 3 seconds and another by less than 10 seconds. (15-20 mins wasted). There were 2 or 3 others where the tube had just pulled away as I arrived on the platform.
Missed an overground connection because I didn't know what platform it left from (15 mins)
Missed a tube train because I was just looking around at one station (10 mins)
Had to look for a bus stop (5 mins)
A Bakerloo service terminated at Queen's Park, then the following service terminated at Stonebridge Park (10 mins)
A Picadilly service terminated at Rayner's Lane (8 mins)
So could have done that section an hour quicker. Just need to get myself physically fit
