One thing I wish I'd done before C25K...is worked out how long I could have run non-stop for before it. Just so I had a record and could keep reminding myself of the progress I am making.
Thinking back now I remember feeling like 3 minutes in Week 3 was really hard (and 1 minute in Week 1 was far from easy!). I almost can't believe now that that can really have been the case, seeing as I can run 30 minutes now as my "standard". Is it possible that that really was my limit?! I certainly was very unfit but perhaps it was a mental thing too?
What about you? How long could you run for before C25K?
