Made me think also of this event & wikipedia article: https://en.wikipedia.org/wiki/Sunday_Times_Golden_Globe_Race

    Nine sailors started the race; four retired before leaving the Atlantic Ocean. Of the five remaining, Chay Blyth, who had set off with absolutely no sailing experience, sailed past the Cape of Good Hope before retiring; Nigel Tetley sank with 1,100 nautical miles (2,000 km) to go while leading; Donald Crowhurst, who, in desperation, attempted to fake a round-the-world voyage to avoid financial ruin, began to show signs of mental illness, and then committed suicide; and Bernard Moitessier, who rejected the philosophy behind a commercialised competition, abandoned the race while in a strong position to win and kept sailing non-stop until he reached Tahiti after circling the globe one and a half times. Robin Knox-Johnston was the only entrant to complete the race, becoming the first man to sail single-handed and non-stop around the world. He was awarded both prizes, and later donated the £5,000 to a fund supporting Crowhurst's family.
