Just completed my first session of Week 3 successfully, and thoroughly surprised myself by really enjoying it.
I got into a (snail's) pace, kept it up, and found that my breathing just went along with that. I didn't feel like my lungs were about to fall out, like at the beginning of Week 1, and I actually found myself looking around and enjoying the scenery. The scenery is mostly bushes, because I run along a path/cycle path that used to be a railway line, but they're nice bushes!
It wasn't easy, and I'm very slow, but I never thought I'd be able to run for 3 minutes, and now I'm really looking forward to trying to run for 5 mins next week!
