Just discovered this site today, so blogging after the fact about runs 1 and 2.
I am overweight, but have a reasonable level of fitness already, though I've never really been much of a runner. I can cycle for hours, climb stairs, whatever, but running has always defeated me. I was looking for a change in my exercise routine, so I thought I'd give this a go.
I found runs 1 and 2 to be fine. Some muscle ache in my legs the next day after 1, but nothing after 2.
For an additional challenge, I'm going to be on vacation for weeks 3-5, so it will be hard to keep up with the programme, but I'm planning on how to persevere!
