Staggered, stumbled and at times had to resort to crawling on all fours, using hardened hands and knackered knees but I got there in the end!

I'd like to tell you all it was an absolute doddle but I would be lying, by god it was tough, more than once I thought I'd be calling on the services of Kent Air Ambulance Trust - or their Chinese counterparts - to airlift me out of there double quick.

But then, if it wasn't tough, it wouldn't be much of a challenge, would it? And I can now look back on it with a greater sense of achievement because, as we were told througout the trek, that's precisely what it was.

All in, and I am just about all done in, it was something I'm pleased to have done and I want to thank Kent Air Ambulance Trust for giving me the opportunity to do so and most of all I want to express my genuine heartfelt thanks to all of you who generously donated to make it all possible.

I thank you.

Mark,
