Hi I'm delighted to have found this site and just joined. I finished the first 2 weeks of C25K with plenty of huffing & puffing but have a question about week 3. I did the first run yesterday on the treadmill and prefer to listen to my own music rather than the podcasts, and I interpreted the run as follows: 90s run, 90s walk, 3m run, 3m walk, all done 3 times?? I've always thought 2 repetitions of something was to repeat 2 more times?? It seemed very long when I was on the treadmill (and I hope the neighbours didn't hear me shouting "come on, you can do it")!!
