Haru Urara is the ultimate underdog. If you’ve spent any time in Uma Musume: Pretty Derby, you know the pink-haired bundle of energy isn't exactly built for traditional greatness. She has terrible aptitudes. Her stats are a mess at base level. Yet, she’s the soul of the game. Honestly, most players treat her as a meme or a "money grinder" because of her unique interaction with the URA Finals, but if you actually want a functional urara uma musume build that wins races rather than just losing them for rewards, you have to throw the standard playbook out the window.
You can't just slap a speed/stamina template on her and hope for the best. It doesn't work that way.
The problem starts with her Mile and Dirt ratings. While she’s the queen of the dirt, her distance aptitudes are claustrophobically narrow. She basically only wants to run Short or Mile. Try to push her into a Long-distance race, like the Arima Kinen, and you’re looking at a legendary disaster—literally, the game is programmed to make that a pivotal, heartbreaking moment in her story. But we aren't here for the tears. We’re here to build a pink rocket that actually crosses the finish line first.
The Strategy Most People Ignore
Basically, you have two choices: the "Guts Meta" or the "Standard Speed/Power" approach.
Back in the early days of the Japanese server, everyone thought Guts (Root) was a dump stat. They were wrong. For a dirt runner like Urara, Guts is actually kind of vital because of how the dirt tracks affect positioning and stamina drain. However, in the current 2026 meta, we’ve learned that a urara uma musume build thrives most when you lean into her "Sashi" (Betweeners) or "Oikomi" (Chaser) traits.
Wait. Urara as a Chaser?
Yes. It sounds fake, but it's the secret sauce. While she’s naturally a Betweener, her kit works surprisingly well if you use inheritance to bump her Chaser aptitude. It keeps her out of the "dirt" literally and figuratively, avoiding the blockages that happen in the middle of the pack. If she gets trapped in the crowd, her low Power will keep her there. She'll just bounce around like a pinball.
Inheritance is Non-Negotiable
You can't just pick random parents. If you’re serious, you need to fix her distance ratings first. Her Mile rating is a B. You want that at an A or S. Her Short rating is also an A, but most high-level Dirt races in the game are Mile-length. If you don't bring that Mile rating up, you’re fighting an uphill battle from turn one.

Focus on parents with high Power and Stamina blue factors. Why? Because you’re going to spend your training turns on Speed and Intelligence (Wisdom). You need the inheritance to do the heavy lifting for her physical bulk. Look for a Oguri Cap or a Taiki Shuttle as parents. Not only do they provide the right turf/dirt compatibility, but their unique skills (inheritable versions) are massive for Urara’s late-game surge.
"Victory Shot!" from Taiki Shuttle is a game-changer. Use it.
Training Priorities and Support Cards
Forget balance. Balance is for winners who have good base stats. Urara needs spikes.
In your training sessions, you’re looking to max out Speed. You want that 1200+ (or the 2026 cap depending on your scenario). But the secondary stat isn't Stamina—it’s Intelligence. Dirt tracks are brutal. The "debuff" from running on dirt is real, and a high Intelligence stat helps Urara trigger her recovery skills and navigate the pack without wasting energy.
For support cards, you want a stack that looks something like this:
3 Speed cards, 2 Intelligence cards, and 1 Friend/Group card.
Kitasan Black (SSR) is still a staple for a reason. The "Arc Maestro" skill is generally the gold standard for stamina, but for Urara, you might actually prefer "Agility" or dirt-specific recovery. If you have access to the newer 2025/2026 dirt-specialized cards like the SSR Hokko Tarumae, use them. They offer "Dirt Proficiency" which is a flat buff to your speed on non-turf tracks.
Don't neglect the "Gamba!" spirit. Urara’s unique skill, "Waku-waku Stand-by," triggers when her stamina is low in the final stages. It’s a recovery skill. This is why you can get away with slightly lower Stamina stats than other girls; she has a built-in safety net. But don't rely on it too much. If she’s "Tired" (the blue face icon), no amount of "Gamba" will save the run.

The Mid-Game Slump
Somewhere around the middle of the Senior year, you’ll hit a wall. The races get harder, and the competition starts bringing A-rank stats. This is where most Urara builds fail.
You need to ensure you’ve picked up "Non-Stop Girl." It is arguably the most important skill for any urara uma musume build. Since she’s usually coming from behind, she needs the ability to weave through the crowd without losing momentum. Without it, she’ll get stuck behind a slow-moving El Condor Pasa and your race is over.
Also, keep an eye on her mood. Urara is prone to "Low Spirits" more than some of the more serious girls. A single fail at the Shrine can tank your motivation, and a "Normal" mood Urara loses about 10% of her effective stats compared to "Perfect." Keep those cupcakes ready. Honestly, just use the cupcakes. Don't waste a turn "Resting" if her mood is down; it’s not worth the RNG risk.
Addressing the Arima Kinen Myth
Can she win the Arima Kinen?
Technically, yes. People have done it. But it requires a very specific, very cursed build. You have to force her Long Distance aptitude from a G all the way to an A through multiple stages of inheritance. It takes months of breeding. For a standard competitive build, don't do this. It ruins her for the races she’s actually meant to win. Focus on the February Stakes. Focus on the Champions Cup. That’s where Urara shines.
Skills to Prioritize
- Dirt Runner: Obvious, but necessary.
- Mile Proficiency: Since most dirt G1s are miles.
- Vertical Jump: Helps with her positioning as a Sashi.
- Emerging Determination: A great mid-race speed boost.
- Spread Leg Wisdom: Helps avoid being blocked.
Avoid "General" skills that only work on Turf. It sounds stupidly simple, but I’ve seen so many people equip "Turf Adept" because the card gave it to them for cheap. It’s a dead skill slot. Total waste.
The Actionable Roadmap for Your Next Run
If you want to stop losing with Urara, follow this specific flow on your next training attempt.

First, start by selecting parents that give at least 9 stars in Power. You need that raw acceleration. Make sure at least one parent has a 3-star Mile factor to bump her aptitude to A immediately.
In the Early Game (Junior Year), focus almost entirely on building your bond with support cards. Don't worry about the stats too much yet. You want those "Rainbow" training sessions to pop as early as possible in the Classic year. Aim to have at least 300 Speed and 250 Intelligence before her first major debut race.
During the Classic Year, prioritize the Speed/Intelligence training loops. If you see a Guts training with 3 or more people, take it once or twice just to keep her from being too fragile, but don't camp there. By the time the summer camp hits, you should be pushing for 600 Speed.
In the Senior Year, start buying your skills. Don't wait until the end. If you have "Non-Stop Girl" or "Positioning Sense" available, grab them before the big G1 races in the autumn.
The final stretch is all about the URA Finals (or whichever scenario you are running, like Project L'Arc). If you’ve hit 1000 Speed and 600 Power, Urara will breeze through the dirt tracks. The beauty of a well-optimized Urara is that she becomes the most consistent earner in your stable. She doesn't need the flashy 1500 Stamina builds that the long-distance stars require. She just needs to be fast, smart, and lucky enough to find a gap in the final 200 meters.
Stop treating her like a joke character. With the right urara uma musume build, she’s a legitimate contender in the Dirt CM (Champions Meeting) and a nightmare for opponents who underestimate the power of "Gamba!"
Next Steps for Your Stable
- Check your current inheritance pool for 3-star Mile or 3-star Dirt factors; if you don't have them, rent a friend's parent immediately.
- Filter your support cards for "Non-Stop Girl" (look for the Yukino Bijin SSR) and prioritize including it in your deck.
- Run a test training focusing solely on the Speed/Intelligence split to see how high you can push her "Wisdom" without sacrificing her top-end velocity.
