After weeks of mumbling about it, I finally started C25K+ this morning. In one word : Magic. Now why didn't I do it straight after C25K I don't know, but my loss !
By the time I reach the 165 beats per minute, I carried on just a bit more to do 5K. I think I will stick to it for a while. I like the way Laura reminds you about posture. I seem to go into a dream world and hunch up so Laura is great at reminding me to relax. I also notice my shuffle has more of a spring to it. Conclusion: new graduate "do yourself a favour" and go on to C25K+.
