I am going to be 55 in 8 weeks. I needed to get fitter so I challenged myself. I’ve completed weeks 1-4 and did my second run of 2x8 minutes this morning!! I’d had a sleepless night, worrying whether I could run for even one solid 8 minutes, but I managed it. Can’t walk now but it was worth the pain. Before this, the last running I did was age 14 at school. I seriously never thought I could do it. Problem now is the 20 minute run I’m due to attempt on Saturday. I think I need all the encouragement I can get. I don’t get how, from 2x8 minutes, the next step up is 20 minutes solid. What have others done? Is this correct?
