I've finished my rest week with a quick 6.8km to give me a total above 30km which is fine. Although this was a fairly easy run I determined to make a bit of an effort and I was rewarded with a clutch of Strava awards including a best mile at 6:55 minutes. That won't trouble the record books!
I think that I have also determined that it is the nice fast Brooks shoes which rub my heels. I've done 3 runs in them this week and the skin has become increasingly sore. No blisters, just a little irritation.
