I'd been dreading it for weeks, but my marathon training schedule has just thrown up my first mid-week 8 mile walk. This is more a question of logistics than distance, although I'd be lying if I said I wasn't also a little nervous about the prospect of clocking up 34 miles of training this week.
Anyway, all this was put into perspective yesterday when I found out about Matt Green, a man who is walking from one side of America to the other.
This awesome journey from New York to Oregon, which he started in March this year, will cover 3100 miles. He is aiming to complete it in 9 months (this includes plenty of rest days) and will be relying on his tent and the kindness of strangers along the way.
I am completely in awe of Matt, and just a little bit jealous. I became even more impressed when I discovered that his challenge is self-directed by his search for adventure. There's no charity, no world record, just a chap who wants to walk. And explore. And document his journey with some intriguing photos as he goes.
If you want to be just as stunned as I am, and also see some great photos from his journey so far, I strongly urge you to go and take a look at Matt's site: imjustwalkin.com
