So I started the C25K today, and I was actually surprised at how easy I found it. I always considered myself to be a terrible runner, but I've seen posts on various sites by people saying they really struggled/felt sick etc after the first days of C25K. I barely even felt out of breath at any point, which was a huge surprise to me. I'm just wondering if I should be pushing myself to the point where I'm out of breath at the end of each jogging interval or what? My average walking pace was 8:10 min per km and my average jogging pace was 5:45 min per km. No idea if these are fast or slow though.
