Earlier in the year I set myself a challenge to walk 500 miles by the end of July, see my original post here: 500 Miles.
At the time I said it might not seem much of a challenge, but to me it was (and is) as I change my lifestyle.
Clearly it's not in the same realms as Davina's Comic Relief challenge where she also covered 500 miles in a much shorter timescale, but it's my personal challenge about how to stay more active in my home-based life.
Some people I know, on learning of this challenge immediately dismissed it and said I'd do it no problem.
And at the start I did wonder if I'd been too easy on myself, however as the months have gone on and other things have vied for my attention walking my twenty one miles a week hasn't been so clear cut at all.
