I was worried last week and posted about this run. After reading the advice I went for it today and am really, really pleased that I completed it. My ankles of all things felt heavy in the first couple of minutes, but I ignored that and carried on. I was pleased to get the updates from Michael Johnson in the app as I plodded along. I was breathing hard by the end and was very pleased when he told me to slow down to walking and I got all wobbly legged but half an hour later I am on top of the world. I have never in my whole life run for that length of time. I managed 3.7km, so by the time I take out the two 5 minute walks, I reckon that is about 3.2km in 20 minutes. I am very pleased with myself and can hardly believe I have come this far.
Thanks for all the supportive messages in the last couple of days - I really think they made the difference between repeating a week or actually going for it.
Keep up the good work everyone!
