The day was hot, 33 degrees I think, I was tired and next week's progam looks rather formidable! Not so sure about this 6 week 5km training; it's becoming a load of running this week but, since I'm half way through, I might as well finish it. Always take a rest day if needed or just walk! There are a number of other programs, up to 12 weeks, not so heavy and not aimed at any specific race distance. I might try one of those when/if I finish another 3 weeks of the one I've started.
