Uma Musume Stamina Calculator: The Complete Trainer’s Guide to Never Running Dry Again

Every trainer in Uma Musume: Pretty Derby has lived through that painful moment — the final stretch of a G1 race, your horse girl surging with everything she has, and then the dreaded slowdown. She runs out of fuel twenty meters from the finish line, and the field gallops right past her.

That single mistake can cost you a champion’s meeting slot, a clear scenario, or weeks of careful training. And almost every time, the root cause is the same: not enough stamina, or the wrong stamina for the race type.

This guide exists to make sure that never happens to you again. Below you will find everything you need to understand how the stamina system actually works in Uma Musume, how to read and use the calculator on this page, and how to build Uma builds that finish strong — every single time.

What Is Stamina in Uma Musume: Pretty Derby?

Stamina in Uma Musume is not a simple endurance bar. It is a hidden HP pool that depletes at a rate determined by your Uma’s speed, running style, race distance, track surface, and track condition. When that HP pool hits zero during the final spurt phase, your Uma automatically enters a “throttled” state and loses speed, regardless of how high her speed stat is.

This is why trainers often say that speed without stamina is wasted potential. A 1600 speed Uma who runs out of stamina at the 200 m mark will lose to a 1200 speed Uma who finishes with fuel to spare.

The core stamina formula works roughly like this:

• Your Uma starts the race with an effective HP pool based on her Stamina stat
• That pool drains continuously at a base rate tied to race distance
• Her running style multiplies that drain rate (front-runners spend more; end closers spend less early on)
• Track surface and condition apply additional multipliers
• Recovery skills restore a percentage of max HP when they activate
• Guts reduces the severity of the throttle effect when HP runs low

This is why eyeballing stamina never works. There are too many interacting variables — and the difference between “fine” and “crashes at the 400m mark” can be as little as 80 stamina points.

How to Use the Uma Musume Stamina Calculator

The calculator above is designed to remove all guesswork from this equation. Here is a step-by-step walkthrough.

Step 1 — Enter Your Race Distance

Race distance is the single biggest driver of stamina requirement. A 1400m sprint needs roughly 600–700 effective stamina. A 3200m long-distance race can demand 1400+ before modifiers.

You can find the exact race distance on the race information screen inside the game. Always use the actual race distance, not an approximation.

Step 2 — Select Your Uma’s Running Style

Running style changes when and how fast your Uma burns stamina:

• Front Runner (Nige): Leads from the start and maintains a high pace throughout. Highest stamina consumption of all four styles. Front-runners generally need 10–15% more base stamina than other styles at the same distance.
• Pace Chaser (Senko): Sits just behind the leader. Slightly lower burn rate than Nige, but still front-loaded.
• Late Surger (Sashi): Conserves energy in the middle of the race before pushing hard. More stamina-efficient mid-race but still demands a solid pool for the final spurt.
• End Closer (Oikomi): Saves nearly everything for the last stretch. Lowest early consumption — but needs enough HP to sustain the massive speed burst at the end.

Selecting the wrong style in the calculator will give you an incorrect result. Match it exactly to your Uma’s race plan.

Step 3 — Set Track Surface and Track Condition

Track Surface:

• Turf (芝) is the standard surface and uses the baseline stamina formula.
• Dirt (ダート) increases HP drain by approximately 7% due to the higher resistance. If your Uma races on dirt, always account for this, even if she has an S aptitude for it – the drain increase applies regardless.

Track Condition:

• Firm (良) is optimal. No modifier.
• Good (稍重) adds a minor drain increase — small enough that most builds will not notice it.
• Soft (重) and Heavy (不良) both add roughly +2% HP consumption per second throughout the race. In a 3200m race, this can translate into needing 50 or more extra stamina points. Heavy conditions also reduce the speed by 50, which compounds the problem.

Always check the forecasted track condition before a champion’s meeting or an important PvP race. A build that barely clears a firm track can fail badly on a heavy one.

Step 4 — Input Your Uma’s Stamina and Guts Stats

Enter the stats from your Uma’s profile screen. One critical warning: do not use Career Mode values. Career Mode applies a hidden +400 to all stats as a temporary in-scenario bonus. This inflated number will make the calculator give you false confidence.

Always use the real trained stat from Uma’s character page.

A note on Guts:

Guts does not directly increase your stamina pool, but it reduces how badly your Uma throttles when stamina runs low. A Uma with 200 Guts running out of HP will slow down dramatically. The same Uma with 600 Guts will slow down much less — effectively extending her competitive pace even past the stamina threshold.

Recommended Guts targets by distance:

Distance Category	Minimum Guts
Sprint (1200–1400m)	200–300
Mile (1600–1800m)	300–400
Mid (2000–2400m)	400–500
Long (2600–3200m)	500–600

These are not hard rules — Guts is a safety net, not a substitute for base stamina. But investing in Guts on a long-distance Uma is almost always worth the training turns.

Step 5 — Set Mood / Condition

Your Uma’s mood applies a multiplier to both stamina and guts:

• ⭐⭐⭐ Great (絶好調): +4%
• ⭐⭐ Good (好調): +2%
• ⭐ Normal (普通): ±0%
• 💧 Bad (不調): –2%
• 💧💧 Awful (絶不調): –4%

At 1200 stamina, the swing from great to awful is about 96 effective stamina points — the equivalent of more than one full training session. For competitive races, try to enter at Good or Great whenever possible.

Step 6 — Add Recovery Skills

Recovery skills are arguably the most powerful stamina-efficiency tools in the game. Instead of training another 100 points of stamina, a single gold recovery skill like Maestro or Arc Maestro can restore 5.5% of your Uma’s max HP mid-race. At 1200 Stamina, that is roughly 66 HP recovered — essentially free.

Recovery skill tiers:

Skill Tier	HP Recovery per Activation
White / Non-Unique	1.5% – 3.5%
1–2 Star Unique	~5.5%
Gold Skills (Maestro, etc.)	~5.5%
3-Star+ Unique	~7.5%

Important: Gold recovery skills activate at roughly a 70–80% chance per race. This means they are powerful but not guaranteed. Do not build a strategy that assumes every skill fires every race. The calculator factors in the number of Gold skills you have and accounts for their expected value.

Enter the combined HP recovery percentage from all skills on your Uma. If you have one Gold skill (5.5%) and two white skills (3% each), enter approximately 11.5%.

Step 7 — Configure Track Modifiers

Downhill Sections:

Some tracks include significant downhill stretches that reduce stamina consumption because Wit allows the Uma to increase speed without a corresponding HP drain penalty. Hanshin 3000m, for example, consumes notably less stamina than Kyoto 3000m at the same distance — purely because of how the downhill segments interact with the stamina formula.

If you are planning for a known track, select the appropriate modifier. If you are unsure, leave it at None.

Enemy Debuffers:

In Champions Meeting and competitive PvP formats, opponents may run debuffer skills that force pace disruptions. These disrupt your Uma’s optimal pace and can raise actual stamina consumption above the theoretical baseline.

If you are racing in a debuffer-heavy environment, add the appropriate buffer. It is better to carry 30 extra stamina points than to run dry because an opponent’s skill is fired at the wrong moment.

Understanding Your Results

The calculator gives you three key outputs:

Required Stamina — The raw stamina pool your Uma needs to complete the race without throttling, accounting for all modifiers you entered.

Your Effective Stamina — Your Uma’s actual stamina after applying mood, guts bonus, and recovery skill value. This is the number that matters.

Surplus or Deficit — The gap between the required and the effective. ‘Positive’ means she finishes with fuel remaining. ‘Negative’ means she will throttle before the line.

The Stamina Coverage percentage tells you how safely over-built or under-built your current setup is. Targeting 105–115% coverage is a reasonable range for most competitive builds – enough builds – enough buffer for a bad-mood day or a skill not activating, without wasteful over-investment.

Common Stamina Mistakes Trainers Make

Mistake 1: Treating stamina as a flat threshold

The required stamina for any race is not a single fixed number. It shifts based on your running style, the track condition on race day, and whether your recovery skills actually activate. Always plan for a realistic worst-case – good condition, one recovery skill failing, and normal mood – not the best-case scenario.

Mistake 2: Ignoring running style, stamina, and front-runner

A front-runner build for a 3200m race needs significantly more stamina than an end-closer build at the same distance. Many trainers copy a build guide without adjusting for their Uma’s actual style, then wonder why she stalls in the final straight.

Mistake 3: Over-relying on Gold recovery skills

Gold skills are powerful, but an 80% activation rate means they fail roughly one in five races. In a single-elimination tournament format, that one failure eliminates you. Always ensure the stamina stat is enough to survive the race, even if every recovery skill fails — treat the skills as a bonus, not a foundation.

Mistake 4: Forgetting dirt’s stamina tax

Dirt adds approximately 7% drain. A Uma built for turf at 1000 Stamina will run short on a dirt track. If your Uma’s race schedule includes both surfaces, build to the higher requirement.

Mistake 5: Neglecting Guts on long-distance builds

Guts does not show up in traditional “required stamina” calculations, but its effect in real races is significant. An Uma wigutsinaguts will lose several body lengths when stamina runs low. An Uma with 600 Guts will push through and stay competitive. For 2400m and longer races, Guts is a race-winning stat.

Stamina Targets by Distance and Style

Use this reference table as a starting point for planning builds. These numbers are as good, normal condition, normal mood, and no recovery skills — adjust upward if you expect heavy track conditions or competitive debuffer environments.

Distance	Front Runner	Pace Chaser	Late Surger	End Closer
1400m Sprint	700	650	620	600
1800m Mile	850	800	760	720
2400m Mid	1050	980	940	900
2600m Long	1150	1070	1020	980
3200m Long	1400	1320	1250	1200

Once you add a Gold recovery skill, you can typically reduce these targets by 60–80 points. Two gold skills bring it down further. The calculator above handles all of this automatically when you enter your skill information.

How Stamina Interacts With the Last Spurt

The last spurt is the final phase of every race — typically the last 200 m200 m to 600 m, depending on distance — where all Uma Musume push to their maximum speed. This is where stamina becomes the deciding factor.

An Uma who enters the Last Spurt with full HP maintains her maximum speed multiplier throughout. An Uma who enters with low HP will have her speed reduced proportionally. An Umthattho that runs completely dry will slow to a walking pace relative to the field.

Guts modifies exactly how severe the slowdown is when HP runs low. This is why Guts feels invisible in good races (your Uma finishes with HP remaining) but becomes crucial in hard races (she pushes through the pain and still places well even when cutting it close).

The calculator’s surplus/deficit output tells you how much HP your Uma has at the start of the last spurtlast spurt phase — which is the true measure of whether she will win or fade.

Building Smarter: Using the Calculator in Your Training Loop

The best way to use this tool is not just before a race — it is during training sessions to set targets.

1. Decide your target race before you start training (e.g., the Championsthe Champions Meeting on a 2400 m2400 m turf track).
2. Enter the race parameters into the calculator with your Uma’s planned running style and expected skills.
3. Read the required staminarequired stamina output. This is your training target.
4. As you train, check back periodically. Once your Uma’s effective stamina clears the required threshold with a 5–10% buffer, you can shift training focus to speed, speed, power, power, or wisdom.

This prevents over-investment in stamina at the cost of other stats — a common trap that produces Umas who never run out of energy but also never run fast enough to win.

Frequently Asked Questions

Q: My Uma shows 1400 stamina in career mode, but the calculator says she needs 1200. Is she safe?

Career Mode adds a hidden +400 bonus to all stats. Your Uma’s stamina is likely around 1000, which puts her below the requirement. Always use the stat from the character profile page, not the Career Mode training screen.

Q: Should I always train stamina to the maximum possible?

No. Stamina above the required threshold, with your recovery skills failing, is wasted training potential. Once you clear the target with a reasonable buffer, redirect those turns to Speed or Wit.

Q: Does distance aptitude affect stamina consumption?

Distance aptitude does not directly reduce stamina drain, but it affects the speed and power multipliers during the race. An Uma racing outside her best-distance aptitude runs less efficiently overall, which can indirectly make stamina management harder.

Q: My Uma has great skills, but still stalls at the end. What is wrong?

Skills have an activation rate, not a guaranteed trigger. If your Uma is running on razor-thin stamina and relying entirely on a Gold skill to save her, she will fail the races where that skill does not activate. Build enough base stamina to survive without the skill, and treat skill recovery as the bonus it is.

Q: How does mood affect long races versus short races?

The mood multiplier applies as a percentage of your Stamina stat, so its absolute value scales with your stat. A 4% mood swing on 600 stamina (sprint) is 24 points. The same 4% on 1400 stamina (long distance) is 56 points — more than half a training session. Mood management matters more for long-distance builds.

Final Thoughts

Stamina is the unglamorous foundation that every great Uma Musumd is built on. Speed wins races when everything else is equal. Stamina ensures everything else stays equal all the way to the finish line.

The calculator on this page accounts for every meaningful variable: race distance, running style, surface, condition, Guts interaction, mood, recovery skills, track topology, and competitive environment. Enter your information, read the results, and build accordingly.

Your Uma trained for months to reach this race. Give her enough fuel to finish it.
