The Secret to Winning in Uma Musume: Stamina!

Welcome, Trainer! In the dazzling world of "Uma Musume: Pretty Derby," you know that raising a champion is a delicate dance of stats. While Speed is what gets you ahead and Power is what helps you push through the pack, it's **Stamina** that carries you across the finish line in first place. Think of Stamina as the fuel in your Uma Musume's tank for the entire race. If that tank runs dry before the final stretch, her speed will plummet, and you'll have to watch in agony as the competition gallops right past her. It's a heartbreaking experience that every trainer has faced.

But how much fuel does she need? That's the million-dollar question. The answer is surprisingly complex. It depends on the **Race Distance**, of course, but also on her **Running Style** (a front-runner burns fuel differently than a chaser), the **Track Condition** (a heavy track is more tiring), and even her hidden "second wind"—the **Guts** stat. This is where this calculator becomes your most trusted training partner. It takes all the complicated, hidden in-game formulas and turns them into a simple, clear answer. It doesn't just tell you a number; it helps you understand the *why* behind it. It's designed to take the guesswork out of your training plan, giving you the confidence to know that when your girl enters the final leg of the race, she'll have all the energy she needs to leave everyone else in the dust.

How to Use the Calculator

Finding your Uma Musume's required stamina is a quick and easy process that gives you instant feedback:

1. Enter the Race Details: Start by typing in the **Race Distance** in meters. You can find this on the race information screen in the game.
2. Input Your Uma's Stats: Enter your horse girl's current **Stamina** and **Guts** stats exactly as they appear on her profile.
3. Set Your Strategy: Choose her running style (Runner, Leader, Betweener, or Chaser) and the race's **Surface** and **Track Condition**. These small details can make a big difference!
4. Add Recovery Skills (Important!):** If your Uma has any skills that recover stamina (the gold ones are the best!), add up their percentage values and enter the total here. For example, the famous "Maestro" skill is worth 5.5%. This is a crucial step for an accurate calculation.
5. Check Your Results Instantly: The calculator will immediately show you the "Required Stamina" for the race. The visual bar will show you if your current stamina is above or below this target, and the "Effective Stamina" card will show you your total endurance pool, including the help from her Guts stat.
