Jume to ucucu (E16)

A runner from another school trips and falls right in front of Haiji. Fortunately, he's able to avoid crashing into him, but he puts all his weight on his right leg. The fall causes a commotion at the water station. The cold rain mercilessly pounds down on the runners and the fans watching over them. Eventually the races moves into the city streets, and the runners' race for survival accelerates. (Crunchyroll)
