I'm a lazy bastard at heart. I have started c25k because I want to lose weight, and while I want to become a regular runner, I *know* that if there's no carrot dangling in front my head, I'll start to skip runs once I have graduated. For the time being, the graduation is the carrot, and I need to prepare another carrot to make sure I continue running.
So I've decided that after my first official 5k (coinciding with my expected graduation run) on the 27th April, I will start to train for 10k. I'm considering a 10k run on the 15th June. That's 7 weeks after the 5k. The way I see it, I should be able to increase my running time by 5 minutes per week, meaning it ought to take 6 weeks to get from 5k to 10k.
Is this likely to be realistic? What do those of you graduates who have gone on to run longer think?
