Hi! I'm new on this forum but I signed up feeling like I need a community to be part of. I don't know any other runners, so I'm out on my own and now I've reached week 4. Type C25K into Google and it suggests 'week 4 is hard' so I'm a little scared. I've enjoyed the programme so far, having not exercised properly since leaving school almost 20 years ago. Any advice for week four? How did you find it?
