Seems like it was the right decision to push on with W5 after my involuntary and premature jump into W5 on Monday. 8 minutes running goes a lot faster than 5 minutes walking ! The gremlins always mutter away during the first 2 minutes "this is tough. You have a long way to go. Are you sure you can do this? Shouldn't you stop?". But if I ignore them and push on they shut up. They mutter whether the run is 3, 5 or 8 minutes, so it seems to be part of the ritual!
Over half way there! Will give myself 2 days rest before the big 20 mins on Saturday. Part of me is looking forward to it. But those gremlins are still muttering "20 minutes, that's AGES. You can't do that! Your knees are already sore. Aren't you overdoing it?". You get the gist. My knees are always sore, but they get worse if I don't walk or run so I think I'll just let the gremlins mutter and ignore them!
