Given that it's taken me a good half an hour to navigate Just Giving and set up this page (I'm still not quite convinced that I've joined the right group - shall shortly discover that I'm now back-flipping across the Serengeti for the protection of cats in YouTube clips charity), the chances of me navigating the highest peaks in England, Scotland and Wales are relatively slim.

BUT everyone loves an underdog and the run I've just done around Regents Park in a bid to get my lungs in slightly better shape has just proven that this dog is more "under" than most.

If the belly laugh that the thought of me hoofing it up 23 miles of mountain in under 24 hours isn't enough to make you dig deep for our chosen charity Crisis, please let the fact that 5,678 people slept rough last year in London alone (nearly enough to fill the velodrome in the Olympic park) be enough to click donate and make the blood, sweat, tears and light-headedness really worthwhile.
