Well, I have news for you, you are not. C25K is about endurance, not pace.
Look at it this way. Mo Farah may run a marathon in 2 hours giving it 100% yet the person at the rear has run the same distance in 8 hours also giving it 100%.Who is working the hardest?
C25K is just the same, there is no such thing as a slow runner. We run at a different pace but still give the same effort, if not more. Where you are in the program is irrelevant. You are out there. You are doing it. Give yourself credit, you are faster than those still on the couch.
So keep running but not too fast and enjoy it.
