Started off from Thurrock at around 13:20 ish. Did about 40 miles round to the A3. Surprised so many left the convoy at Clacketts Lane services, the A22 junction and again at Cobham services, as it's very difficult to make this happen if people quit so early. I don't actually know in the case of the M25 whether or not the "ring of red" has ever been achieved. Well done to all those(M25/M60) that gave it a go though.
