Running is a great way to use some extra kilojoules as well as improve your overall health and fitness. Running is one of the top energy consuming activities available to you and it's right outside your front door!!. Here are a couple of examples of the amount of kJ’s burned during a 10k run. A 60kg person will burn approximately 2715kj (649 calories) an 80kg person will burn around 3623kJ (866 calories). By adding a couple run’s to your week you can burn off a lot of excess energy (kJ’s). Combining this with 2 or 3 gym sessions each week will have a big impact on your general health as well as controlling your body weight. Most people will still need to control the number of kJ’s they consume each day, and if you are just starting out, all the extra activity can increase your appetite, so you need to be careful not to over eat!
