I thought I should repeat W6R3 because I walked after 20 mins and it was hilly, so I went to the river where it's flat, but what a hard run!
After 5 minutes I needed to walk, and my pace definitely wasn't too fast, and I wondered if I should even attempt any more. I was just knackered and mentally in completely the wrong place.
After about 90 secs walking I thought I'd just see what I could do, no pressure to even finish, and I really don't know how I did it, but I somehow managed to finish it. But it was SO HARD. Several times I nearly stopped and gave up. I think maybe my body didn't want to do it today and I should have had an extra days rest. I also think I was focusing too much on it instead of relaxing my mind. So I don't know if it counts or not, but I don't want to get stuck on it because mentally it could become a barrier so I think I'll move on to W7.
