Big mistake yesterday. After running 5k in 32 minutes on Tuesday, I felt so good that I thought I would time myself over 1.5 miles (my original aim before starting). Thinking that it was only half the distance, I figured I was able to push even harder and run around 5:00/km. Maybe I can after a suitable rest, but yesterday I certainly couldn't. It was the first time since week 6 where I had to walk a portion, and even produced my first mouthful of vomit 2/3s of then way round. Having said that, my 2.5k pace was still around my pace of the previous day. I think I'll consolidate my 5k pace before trying that again!!
