I am amazed to have completed Week 5. Being a 48 year old mum with wobbly bits I always said I don't do running, but this program is ideal for me. I wasn't sure if I would complete 20 minutes jogging, but I've done it and am really pleased with myself. I'm not at all fast and have dubbed my jogging 'plogging' (plod+jog) but it works for me. I think the dog took longer to recover than me! Roll on Wk6 ... now can actually imagine being able to jog for 30 minutes.
