I completed week nine and decided to keep repeating it to build up my fitness before thinking about progressing to a longer distance. I would say that you do need to keep motivated - it would be easy to just stop now that you have made it to week 9. The positive is that I am definitely much more comfortable doing the 30 minute run now and seem to be covering about the right distance. I am now going to join one of the local 5K park runs in addition to continuing with the rinse repeat of Week 9.
What are other folks doing post week 9?
