Haru Urara (terminal illness)

In the world of racing, races are divided into five types according to their prestige and prize money: Debut Race: This is the first race every Uma runs. It serves as an official introduction to racing and showcases the Uma's ability against others of the same level. It offers no prize money. Open Race: Races where any Uma can enter regardless of experience. They offer varied prizes but do not affect the winner's fame as they are open to all. G3 Race: G3 races are the entry-level races. Umas with little experience participate, and the prize money is the lowest. G2 Race: The second level of racing, these races feature more experienced racers and offer a medium prize money. G1 Race: Among the most prestigious races, these offer the largest prize money and are attended by the most experienced racers.

These are measured according to their distance: Long: the longest, 2 to 3 kilometers, that is, the complete circuit of the racetrack; Mile: a medium distance of 1.7 to 2 kilometers; Sprint: the shortest distance of 0.9 to 1.6 kilometers.
