I started the beginners running schedule today and can't believe how unfit I am. I could only do half of the 8 sets of run 1min walk 90secs before I started feeling sick and a bit dizzy. Did anyone else have problems just doing the east stuff? I think the problem might have been that I was going downhill and I didn't realise how steep it was until I turned round to go uphill. I will try a flatter area on Wednesday.
