slightly off topic, i think, but i rode hull to london at the weekend and the routesheet we had has several sections that need amending, IMO, and the gpx track we had from the auk website was several miles off track on many occasions. for instance, while the instructions for a DIY stipulate visiting stansted airport services, the gpx track doesn't go closer than several miles to the east. also in spalding the instructions are confusing and force you to make an illegal right turn against the traffic on a one way street. this cost a lot of time, although in the end we were just inside time. i have asked mr undulates for his opinion. but DIY LEL perm riders should be aware of this.
oh, and the instructions take you along a really good cycle path by a river near woodhall spa but the gpx track just follows the main road.
finally, it is a fantastic ride hull to london, and has whetted my appetite for LEL.
