Just thought I would post this here as well as the other forum as an encouragement to anyone struggling, having second thoughts or doubting themselves. 4 months ago today I started Couch to 5k and couldn't run 60 seconds without dying. Today I did 10k for the first time.
The programme is absolutely brilliant and the advice and support on this forum is second to none. Keep going and you will succeed.
Run happy and run safe.
