Okay, so I can now run 5k, of which is I am excessively proud. I can even run 6k. My plan from here is to try to run 3 times a week, with one run adding 0.5k a week up to 10k, one run sticking at 5-6k and one doing intervals. This is essentially in an effort to improve my time. I'm not really getting on with intervals though. In fact that is an over optimistic description. I decided to run for 3k, do 4 intervals of 30 seconds fast, 30 seconds slow and then run the rest up to 5k. I managed 2 intervals; I felt like I was going to vomit, pass out or both. So I walked through the rest of the 'interval' time and ran till the 5k point. I'm not really sure what to do. I am overweight (about 3 stone), so should I just leave intervals till I've lost a bit more weight? Or am i just being a great big wimp? Or should I do them with less warm-up run beforehand? Shorter intervals? If you are doing intervals, how far overall do you run for the run?
