Thought this might be the place to ask.
Currently my run is at 2miles, and takes me 17-18 minutes usually, including a hill (I know I ought to do it on the flat, but its hard to plan a route which doesn't include the hill). I do it a couple of times a week, and have been doing it for quite a while - I started it back in May, but took a break from it September - December, in this period I didn't stop exercising, I did weights but kept the cardio to a minimum.
Would this program work for me, to extend my run to 5k or more? or does it only work for beginners?
