Lately I have been doing a lot of walking.
Once upon a time I used to be a member of a hiking club but then I stopped bothering with it.
Since moving house (3 years ago), I have been walking to and from work each day but that's all I've been doing.
I figured that I needed to get more exercise so this month I have been making an effort to walk more. Every weekend I have gone out walking and I have been increasing the distance each time. Yesterday I did my longest walk ever. I walked almost 20 miles (19.49 miles to be precise).
