A: If running 5 km is your aim and you have poor cardio fitness, the first thing you need to do is cast out any doubt you might have of yourself. Don’t say you are going to try for 5km, say you are going to do it. Running has a lot to do with mindset. Second of all, you need to pace yourself. Don’t go out on your first run and expect to be able to run 5k. Start off with intervals: walk for 2 minutes, run for 1 minute and next time walk for 2 minutes run for 2 minutes. Then you can build yourself up to a 2 km walk/run and work your way up. I recommend getting the run keeper app and registering for a 5km course. It breaks it down simply and within weeks, if you follow it, you will be running 5km. Finally, make sure you are eating enough. One big mistake people make is running on a totally empty stomach and they burn out after a couple of minutes of running. Eat well, time your food around your runs; food is fuel.
