Run a marathon

Running a marathon must be also a good experience, that's why I want to do it before I die. It needs some training and effort to get to do it, but actually that's what makes it interesting. Train during several months or a year to get your target: running the marathon, shows you that you can do anything if you work to get it if your willpower is strong enough, so I'll work for it and someday I'll get to run one of the most famous marathons in the world: like London's or New York's ones.
