Hi Foodie!
We have LOTS of people here who do (and love!) the C25K program. There is even a dedicated thread here:

What sort of eating plan are you following? Most likely, we have a forum for it. You can also post in different areas based on how much you have to lose or by age range.
Wherever you post, settle in and stick around. I'm so glad you found us!
