I am a 55 year old Granny. I started couch back in May and was held up with a knee injury for a few weeks. This morning I completed week 5 with the daunting 20 minute run....it was amazing. Laura said I could do it and I did! Incredible programme. Don't fear the 20 minute run. If you have made it this far, you will succeed. I feel confident now that I will finish the programme and will soon be running for 30 minutes. Go Grannies!!
