Veloviewer Tile Bagging?

MiniGB has to go to Guildford for a sports thing for 2 hours this weekend and that just happens to be exactly where I need to ride to extend my large tile square. A 35km ride will get me the tiles I need to go from 18x18 to 21x21.

In the mean time I've been picking off some local small tiles. Yardinho up 400 in the last couple of weeks. Wimbledon Common is done (barring some private bits of Royal Wimbledon GC) and I'll hopefully get Richmond Park covered by the end of next week with some lunchtime walks. Can get my small tile square up to 32x32 before those RWGC tiles become a problem:

• West is limited by The Roehampton Club, but I've got some tiles in Richmond Park GC to get first
  
• The RWGC tiles to the South mean I need to shift the square 4 tiles to the East to continue, next blocker in that direction is Beddington
  
• North is limited by the ungettable tiles in the Barnes Wetland Centre (shifting 4 tiles East fixes this)
  
• East is pretty much unlimited for now, I think it becomes a problem with the river West of the O2
  
  

As cycling fitness returns I'm hoping to start extending my big tile yard with longer rides. Plan is ride parallel to existing rides to maximise coverage. Should be able to extend my yard all the way up to Cambridge with one or two well planned routes.
