It was also mentioned in the same chapter that he joined a martial arts gym, so add that to the list too.@denji I didn’t remember that but cycling around Okinawa does not mean that he participated in that event. He probably did it on his own at his own pace. It’s a long way but not too difficult if you do it In a few days.
My uncle who does sport from time to time and who has knee cartilages in a very poor state does over 100 km in one go.
And over a months still is a few weeks.
