Marathon – The marathon is a symbol of long hard work to achieve a goal. Since ancient times, the marathon has been considered the ultimate symbol of achievement. If you dream about running a marathon it means that you are currently working on a project that carries with it the promise of glory and achievement. If you dream that you are unable to finish a marathon it means that you are not currently in the position to try to complete a goal that you desire to do. It means that you have been too ambitious and need to set your goals a little lower in order to build up to the level that you want to achieve.
