Done it! Have done 5 x 30 mins over the last 2 week (I only did 1 x 28) to make sure I could maintain it outside, and today I did 32mins. Starting this programme is by far one of the best decisions I've ever made. I'm in complete shock still that I can run for 30minutes.
Anyone who is having doubts at the start, please persevere - the buzz you get when you first do your long run of 20 minutes is worth every ache, pain and drop of sweat!
I am running about 4km in 30 minutes at the moment, so I'm going to now work on getting up to 5km. As soon as I can do that, I'm going to enter my local park run, a sentence I never ever thought I would write!
