By breaking up the triathlon into its three key sports (swimming / cycling / running), will enable you to train harder and wiser than if you were to concentrate on just one of the above. By training in multi sports you will develop both all round muscle toning and high levels of cardio vascular capabilities. This is achieved by breaking down training sessions to enable you to have a good workout, but not to be training over tired or sore muscles, as this will simple result in injury and poor performance. With three different distances in triathlon, you will need to decide which event you wish to train for. • Sprint distance, suitable for beginners wishing to experience their first triathlon. • Olympic distance, the next stage up, the more common race distance, certainly among elite athletes. • Ironman distance, for those that like to push their bodies and minds to the limit.
