Four weeks ago I joined a friend for a 5K Parkrun, which for me was a walk as I was very unfit and I realised I had no idea how to pace myself. I was determined to try again and the following week someone recommended I try C25K to learn how to pace and to build stamina. I downloaded it and have completed week 2 run 2 (which was a bit of a struggle). I have used it to pace myself on the last two Parkruns, but would appreciate some advice on how best to manage it. It took me 47:25 to do the 5K last week, which means the 20 minutes of walk/jog runs out half way round. Is it best to just keep repeating the pattern until I finish, or can anyone suggest what would work best please?
