The in-game races in Uma Musume are actually very intricately designed.

Having a basic understanding of how they work can make training easier and also help you earn top rewards in upcoming PvP events.

That said, trying to explain everything about the race mechanics would basically turn into a full-blown academic paper, so for now, I’d like to give a general overview of what each status stat does.

I don’t play on the English version myself, so the translations I’m using might be a little off.
If you notice anything wrong, feel free to correct me in a reply!
Also, if you have any questions, I’m happy to answer as best I can—don’t hesitate to ask.

In this post, I’ll summarize what each of the stats does and explain which ones you should focus on in general training to make it easier to hit your goals.

I’ll also go into a bit more detail for each stat in replies after this.



There are five main stats in Uma Musume:
•Speed
•Stamina
•Power
•Guts
•Wit



•Speed determines how fast your Uma Musume can run during the final spurt at the end of a race.

•Stamina shows how much energy she has to run the whole race.

•Power affects how quickly she can accelerate and how well she can handle uphill sections without losing too much speed.

•Guts influences how efficiently she can go all-out during the final spurt, using less stamina to perform at full power.
(By the way, in the Japanese version, a special “boost mode” was added later on that scales with this stat—but I’m not sure if that mode has been implemented in the English version yet.)

•Wit helps improve her speed throughout the entire race and also increases the activation rate of her skills.



The two most important stats are Speed and Stamina.

Without enough speed, your Uma Musume won’t be able to break away from the pack in the final spurt.

Without enough stamina, she might start her final push too late—or run out of energy and slow down at the end.

In other words, Speed and Stamina are the minimum requirements to win.

That said, the amount of Stamina you need depends heavily on the race distance.
Overtraining it doesn’t really give you any benefits in most cases.



Next in importance are Power and Wit.

If two horses have the same Speed, the one that can accelerate faster (thanks to Power) will win.
Wit is also important because low Wit can lead to skills not activating reliably or to shaky mid-race behavior.



Lastly, Guts is the least important of the five.

It has a very small effect on race outcomes.
It’s nice to have, sure—but if you need to cut one stat to focus on the others, Guts is the first thing you should drop.



So, for basic training:
1.Prioritize raising Speed as much as possible.
2.Raise Stamina just enough to match the distance of the race.
3.Then, boost Power and Wit as much as you can.

From here, I’ll go on to explain each stat in more detail in the following replies.Image
・Speed

Speed determines how fast your Uma Musume can run during the final spurt at the end of the race.

That said, some Trainers might have a question when they hear this:
“If she’s only fast during the final spurt, wouldn’t she still lose if she’s too slow during the rest of the race?”

Actually, outside of the final spurt, most Uma Musume run at roughly the same speed.
(I’ll explain this more in the Wit section.)

So whether a horse has 0 Speed or 1200 Speed, if their running style is the same, their movement up until the final spurt is almost identical. That’s why the Speed stat has such a significant impact on the outcome of the race.

As a rough estimate, every 100 points in Speed results in a time difference of about 0.1 seconds, or about 2.5 meters, which equals one length.

For reference, the golden speed skill Heart and Soul creates about a 2-meter lead on a 2400m course.
・Stamina

Stamina is the stat used to calculate the maximum HP a horse has during a race.
Short-distance races don’t require much HP, but long-distance races need a lot more.

As a general rule, the “right” amount of stamina is often just enough to make you feel like, “Wait, isn’t this a bit too much?”

The amount of stamina needed varies depending on the race conditions, running style, the horse’s Speed, Wit, and Guts stats, so you’ll need to actually calculate what’s necessary.

There are community-made tools (in the Japanese version of the game) that help you figure out if your Stamina is sufficient.



So, why is Stamina so important?

Because Uma Musume use their remaining HP to determine when to begin their final spurt.

At the start of the race, they run in “normal mode.”
Then, once the final third of the race begins, they check how much HP they have left.
At the same time, they calculate how much HP would be needed to start sprinting right now and just barely reach 0 HP exactly 60 meters before the finish line.
•If they have more HP than required, they immediately start their spurt.
•If they don’t have enough, they hold off on sprinting and run at a slightly faster pace while conserving HP.
Once they reach a point where they can start the spurt, they’ll begin it then.

(Also, sometimes they’ll randomly “lose patience” and start the spurt early—even if they don’t have enough HP. This is a bit of a gamble.)

As mentioned in the Speed section, since most horses run at similar speeds up until the spurt, having less time in the final spurt can have a huge negative impact on your performance.

That’s why ensuring your Uma Musume can start their spurt at the earliest possible moment is so important.
(In the Japanese community, this is often called “maximum spurt” or saidai spurt.)



Recovery skills (those with blue icons) restore HP during a race.
The exact effect depends on the race distance and your stats, but as a rough estimate:
•A gold recovery skill can be considered roughly equivalent to +200 to +300 Stamina,
•A blue (lower-tier) recovery skill is about +60 to +120 Stamina.

However, there’s one important thing to keep in mind when using recovery skills:
They must activate before the final spurt begins.

At the start of the last third of the race, Uma Musume only checks how much HP she currently has remaining.
She does not consider whether there are recovery skills that might still activate later.
So even if she has a recovery skill ready to go after that point—and it would be enough to let her start a maximum spurt—she will still assume she doesn’t have enough HP and will delay her spurt accordingly.

So remember: Make sure your recovery skills activate early.

(That said, don’t trigger them too early—like right after the race starts—because if her stamina is already full, the recovery will go to waste!)
・Power

Power determines your Uma Musume’s acceleration ability.
It also helps reduce the debuff effects of uphill sections of the course.

The higher the acceleration, the longer she can run at high speed, which makes Power an important factor in winning races.
That’s why many Trainers might assume that Power is just as important as Speed.

In reality, though, Power is a mid-tier priority stat.
It’s still important, but slightly less so than Speed.

This is because the acceleration boost gained from raising Power is relatively modest.
Speed contributes more directly to winning outcomes.

Also, when it comes to acceleration, skills are generally more effective than raw Power.
Triggering a well-timed acceleration skill gives a much bigger boost than simply raising your Power stat.
(Raising Power by 100 might only boost acceleration by a few percent, but a properly timed acceleration skill can be 10 times—or more—powerful compared to just raising your Power stat.)

That said, Power is not a stat you can completely ignore.

•Even if the effect is small, Power does contribute to acceleration.

•And more importantly, its effect on uphill sections is significant—if your Power is too low, the slowdown is noticeable.
(For reference, a 100-point difference in Power is roughly equivalent to losing the benefit of half an orange-tier speed skill when going uphill.)

So overall, Power is a moderately important stat.
・Guts

Guts is a stat used to calculate how much stamina is consumed during the final spurt.
It also slightly increases running speed when a horse has run out of stamina, or right after the race starts.

(By the way, this stat was later enhanced to also affect the base speed during the spurt and the effectiveness of a bonus mode that activates during the spurt. However, it’s unclear whether these enhancements are implemented in the English version.)

To be honest, Guts is a stat you can mostly ignore.

It does help reduce the stamina consumed during the final spurt, but the impact is only around 10% to 60% of what your Stamina stat does.
(The wide range comes from the fact that Guts follows a logarithmic curve, and spurt speed and duration vary depending on the race distance and your Speed stat.)

Because of that, increasing Stamina is almost always a more efficient use of your training than increasing Guts, which makes Guts a low-priority stat.

That said, having too little Guts can still hurt performance, so you’ll want at least a minimum amount.
But you don’t need to go out of your way to increase it.

Given how hard it is to raise all five stats, you’ll usually have to sacrifice one or more of them.
In that case, Guts is the first one you should drop.
・Wit

Wit has four main functions:
•Increases the activation rate of skills

•Slightly buffs overall running speed throughout the race

•Increases the chance of triggering Downhill Acceleration Mode, a temporary speed boost on downhill sections

•Slightly increases the chance of entering a bonus mode during Position-Keeping, which affects early race positioning based on running style

(That last one—Position-Keeping—is a bit complex, so I’ll explain it at another time.)



・Skill Activation Rate

Uma Musume will sometimes activate skills during a race—and sometimes not.
The higher your Wit stat, the more likely a skill is to activate.

Here’s a rough chart of activation rates by Wit value:
•Wit 200 → 55%
•Wit 300 → 70%
•Wit 450 → 80%
•Wit 600 → 85%
•Wit 900 → 90%
•Wit 1200 → 92.5%

As you can see, the improvement is steep up to 450, so if you care about skill consistency, aim for at least 450 Wit.



・Overall Speed Buff

Earlier, we mentioned that all horses run at roughly the same pace until the final spurt.
In reality, though, there’s a slight variation due to position changes like passing or being passed.
Higher Wit subtly shifts this variation toward the positive side, improving average speed just a bit.

That said, this effect is very minor.
Unless there’s a difference of 200–300 Wit or more, you probably won’t notice it with the naked eye.



・Downhill Acceleration Mode

While uphill sections apply a guaranteed debuff (as explained in the Power section), downhill sections can grant a buff instead—boosting speed and reducing stamina drain.

However, unlike the uphill debuff, the downhill buff doesn’t always activate.
It’s a chance-based bonus, and your Wit stat affects that probability.

But again, the increase is slow and subtle, so unless there’s a 200–300 point difference, it’s hard to visually detect.



Wit has a noticeable effect on the overall flow of a race, but it’s not as dramatic as Speed.
Once you cross a certain relative difference, the returns diminish, and it won’t result in a huge visible advantage.

So as long as your Wit isn’t much lower than average, you’ll be fine.

In terms of importance, Wit is about on par with Power.
Bonus: Track, Distance, and Style Aptitudes

Each Uma Musume has three types of aptitude: Track, Distance, and Style.



■ Track Aptitude

Track aptitude affects acceleration during the race, providing either a buff or debuff in acceleration calculations.

[Track Aptitude Coefficients]
•S → 1.05
•A → 1.00
•B → 0.90
•C → 0.80
•D → 0.70
•E → 0.50
•F → 0.30
•G → 0.10



■ Distance Aptitude

Distance aptitude affects spurt speed during the final part of the race, applying a buff or debuff during that calculation.
In addition, if a Uma Musume’s aptitude is D or lower, it also applies a debuff to acceleration throughout the race.

[Distance Aptitude Coefficients – Speed Calculation]
•S → 1.05
•A → 1.00
•B → 0.90
•C → 0.80
•D → 0.60
•E → 0.40
•F → 0.20
•G → 0.10

[Distance Aptitude Coefficients – Acceleration Calculation]
•S to D → 1.00
•E → 0.60
•F → 0.50
•G → 0.40



■ Style Aptitude

Style aptitude applies a buff or debuff to a Uma Musume’s Wit stat during the race.

[Style Aptitude Coefficients]
•S → 1.10
•A → 1.00
•B → 0.85
•C → 0.75
•D → 0.60
•E → 0.40
•F → 0.20
•G → 0.10

In all cases, A is neutral, S gives a buff, and B or lower applies a debuff.



Which Aptitude Matters Most?

Of the three, Distance aptitude has the biggest impact on race performance.
This is because the Distance coefficient is applied twice when calculating spurt speed—effectively squaring its influence.

If a horse has S Distance, you can roughly treat their Speed stat as being multiplied by 1.1 during the spurt.



The Least Impactful: Track Aptitude

Track aptitude affects acceleration by only 5%, which is relatively minor compared to the effects of acceleration skills.
While it’s clearly better to have it than not, its overall impact is small.

That said, Track aptitude becomes more beneficial in shorter races, where acceleration plays a larger role.
In short-distance races, its value can rival that of Distance aptitude.



Style Aptitude: Moderately Important

Style aptitude provides a moderate buff by raising the effective Wit stat.
However, since its effect scales with how high your Wit stat already is, it’s not a top priority right now.
When players begin consistently reaching around 1200 Wit, likely in a year or two, Style aptitude will probably become much more important.

Note: Style aptitude does not affect skill activation rate.
Although the buff is applied at the start of the race, skill activation is determined the moment you press the “Start Race” button, before any in-race stats take effect.
Bonus Bonus: The Hidden +400 Stat Buff

During career mode, every Uma Musume receives a hidden +400 bonus to all of their stats.
This is believed to be a mechanic designed to prevent extreme race outcomes—like winning far too easily or losing overwhelmingly—during career races.

As a result, you may notice that an Uma Musume behaves differently in career mode races compared to official post-career races, such as Team Stadium events.
This is especially noticeable with Stamina.
Many players find that an Uma Musume who ran just fine during career mode suddenly starts running out of steam in post-career races—so be careful!



There’s also a way to take advantage of this system.

The +400 bonus is added after base stat calculations are complete.
That means even if an Uma Musume has G aptitude in Style, she’ll still have at least 400 effective Wit during career races.

So even if she’s running in a Style she’s not suited for, she can still perform reasonably well in career mode.



If you’re struggling to win a race during career mode, try continuing and experimenting with different Styles.
Thanks to the hidden bonus, they might perform better than you’d expect.
Bonus Bonus Bonus: How Remaining Stamina Affects Spurt Timing

This video is a great learning tool for understanding how remaining stamina influences the start of a final spurt.

(Plus, it’s full of adorable Tachyon-chan, so it’s also a real treat to watch!)

At the start, Number 1 Tachyon-chan takes a big lead.
If you look closely at the race interface, you’ll notice two vertical lines stretching from the start to the finish.
The line on the right marks the beginning of the final phase of the race—that is, the maximum spurt point.

Because Number 1 Tachyon-chan was in the lead early on, she couldn’t activate her unique recovery skill, and didn’t have enough stamina left.
As a result, even after passing the final third of the race, she wasn’t able to start her spurt.

Meanwhile, Number 7 Tachyon-chan did manage to activate her recovery skill, so she had plenty of stamina remaining.
As soon as she crossed the 1/3 mark, she immediately started her spurt (well, maybe with a slight delay), and with that burst of speed, she quickly caught up and overtook the lead.

Now, take a look right before the finish line.

You’ll notice that one Tachyon-chan is still leaning forward, while the other has slightly lifted her upper body.
That upright posture means her HP has hit zero.
Once that happens, she rapidly slows down, making it much easier for other Uma Musume to catch up from behind.
