I've been on week 1 for 3 weeks now and still can't do it. So frustrated with myself I could scream. After the second running section i'm in agony with my outer ankles, it makes me unable to run so I end up walking most of it then running the last few parts in pain. I have proper running trainers. My dad seems to think its because I'm overweight and my ankles are weak. What can I do to help? I'll never get to 5k at this rate.
