How far can you get from the NPG in 5 mins?

Well, Today we found out how far you could get from the NPG in 5 mins (also 10/15/20). We thought we would make a video to show just how we did it.
Now we have maps to show just how far you can get in those allocated amounts of time, now we can work out what (and who) falls into that catchment area, and how best to communicate with them.
Maps to follow!
