Jake really thought that Zack could be a professional athlete and maybe even win marathons someday, so Jake thought that Jake had to run other marathons to gain more experience on different marathons and on different routes.
Of course, Jake thought that Zack knew that he could only win a marathon one day if Jake was not competing in the same marathon, otherwise it would be impossible for Zack to win him in a marathon.
Jake's goal in the marathons was no longer to win but to try to run in less than 2 hours, and Jake was very close to achieving that, of course, Jake still had to go back to training and he needed to gain more resistance stats and agility to be able to run the marathon in less than 2 hours.
