Not to be particularly picky about it but ... you've walked the Icknield Way Path, not the Icknield Way. The actual Icknield Way (http://en.wikipedia.org/wiki/Icknield_Way) continues into Oxfordshire, and I used to walk 6-15k sections of it yearly as a child for various fundraisers. (I also went to a school named after it, and lived appx 150 yards from it too, come to think of it...)

If you decide to continue and walk the rest of it at some point, I'd be very pleased to tackle a (short) section of it with you. :)
