I have now completed the walk, and survived with only a few scratches.
You can continue to sponsor me on this page.
You can also see photos and read stories from my walk at my weblog:

The walk is also a chance to promote European cultural heritage and to raise money to protect, conserve and present it to the widest possible audiences for present and future generations.
Donating through this site is simple, fast and totally secure. It is also the most efficient way to sponsor me: Europa Nostra London will receive your money faster and, if you are a UK taxpayer, an extra 28% in tax will be added to your gift at no cost to you.
Many thanks for your support.
