The last two food stops on the marathon route had Anpan! I love anpan! It's sweetened kidney beans mashed together and baked inside rolls.
At this stop, they also had raisins and Umeboshi... YAY!!! Umeboshi is pickled plum and it really hits the spot when your physical resources are depleted.
This guy was handing out onigiri, or rice balls.
