One curious aspect of these Games has been the vast over-estimations by the organisers of how long it takes to walk somewhere. The travel website says it takes 26 minutes to walk from my house to Hitchin station: I usually do it in half that. Then there was a sign at Custom House DLR station the other day saying it was 8 minutes to the Excel: it took less than three.
And then this morning, switching from train to tube in Hampstead, they were claiming this journey from a lamp post to where the Underground sign is would take 2 minutes: it was more like 20 seconds. You can only assume they're trying to make us trudging spectators feel like record-breaking Olympians.
