Endurance
Endurance is a Racing Chocobo Stat that affects how long your chocobo can run before becoming exhausted.
Endurance makes the Lathered status last less time on you, which has a subtle benefit when you're budgeting: it means you spend less time decelerating before you can accelerate again. Your speed doesn't drop as much when you're trying to avoid Lathering, means that you spend less time accelerating back up to full speed when you resume accelerating. Overall, it makes your speed when budgeting stamina noticeably faster. It is very useful in races where the item boxes just aren't giving you stamina boosters. I just don't rank it very high compared to other stats because there's a lot of the time when you don't budget, either because you can't (Frenzied) or because you don't want to (plenty of stamina items or an important item box is approaching).
