There’s always one isn’t there? DP took the anticlockwise route (“A for Anarchy”) ” managed to make one complete 80km circuit on the 11A between 12:55 and 15:20. According to [his] GPS unit, that is, which apparently includes the vertical travel as well as the horizontal.”

Photos are being uploaded to this Zoto set, which included him spotting other 11-11-11ers going the other way round:

He has also done some stunning GPS mapping work, which is further delved into here.

[UPDATE: More mapping.]
