So - I wrote in here when I graduated a month or so ago and thought I'd update. I started C25K at 41, a whopping 8 and half stone overweight and a 20 a day smoker with asthma who hadn't done any exercise in 15 years. I completed the C25K (and have now dropped 4 stone to date) at a very slow 3.4-3.5 mph....Well, a lot of you suggested various stuff to help with speed which I put into practise and I am now doing the 5k at 4mph (within 3 weeks of trying it). So now it's on! I really want to run the 5k in 40mins (which appears to be a relatively run of the mill time for normal humans who don't have asthma and a ton of weight on them) so I am doing the whole programme again. So tonight I started Week 1 Run 1 at 4.7mph and I did it (a hell of a lot easier than when I started originally!). So chuffed with myself and I can feel the old enthusiasm of the challenge driving me forward again! I love C25K!!
