Well first run of wk 4 and it was great running in the sun. I thought can I really run another 5 minutes, when Laura said, 'you've done this already.' Yes I had and I managed it, glad to stop I was so hot. Got home and my face was bright red, oh well I've had a proper workout! I didn't think it was warm enough for shorts, good job I didn't wear my running tights! Have found it's not as painful to foam roller as well, so it must be doing something!
