I'm a 40ish woman, massively overweight and grossly unfit. I completed week 1 last week and was on a high. Run 1 of week 2 was such hard work but I got through it with one 30 second pause in the middle. I was apprehensive about W2R2 but actually found it enjoyable and I did it. This morning, I tackled W2R3, confident that all would go swimmingly after my successful W2R2. How wrong I was. My legs felt like lead and it was if I was running through sludge. I got to the end of each running section but had to pause twice for a drink as I was gasping for breath. I'm now scared to move onto week 3 as I'm not sure I'm up to it. Have I taken on too much with this programme?
