I started the C25K program in January, and completed the official program 11 weeks later (I re-did two of the weeks because I wasn't ready to move on). That means I have been running a 5k, 3 days a week ever since. I have improved some, from 10:05 splits to 8:45 splits, but I am getting bored with doing the same thing week in and week out.
So I am coming here looking for ideas. I have thought about going to 6K, but it seems like more of the same. I feel like I need a new goal. As I was perusing the boards today I noticed people talking about 5K racing training, but I am doing this for general fitness, not to be a competitive racer. On that note, I also have lost ~20lbs, but I seem to have hit a plateau there and any advice on that topic would be welcome as well, concerning running for weight loss.
I just completed C25K today so I can't say I am bored with it yet. However looking at the future I see my self also doing trail running eventually to keep it interesting. I still have a lot of weight to lose so I will stay on the roads a little longer and see where they take me. Have you looked at 10Ks? Training for those will also help with 5k's too.
Congrats on keeping with the running and the weight loss.
