I started C25K a while ago and found instead of doing the 3 runs every week I could only realistically achieve 2 a week, generally one in the evening and then one at the weekend. This mainly was due to old injuries which meant my recovery time needed an extra day sometimes.
I’m about to start week 8 so am VERY close to completing the course! If you’re like me and need an additional days rest for those first weeks, you will still get through the process!!
