Race Performance Formula Explained

The Uma Musume race performance formula calculates an overall performance score based on your horse girl's core stats, adjusted by race distance, track condition, and running style synergy. This composite score predicts competitive viability for any given race configuration.

Required Stamina = Base Stamina (distance) × Track Condition Modifier
Stamina Sufficiency = (Stamina Stat ÷ Required Stamina) × 100%
Performance Score = (Speed × Ws + Stamina × Wst + Power × Wp) ÷ 10 × Track Speed Modifier × Style Synergy

Distance Reference Table

DistanceBase Stamina Req.Speed WeightStamina WeightPower Weight
Short (1200m)3000.450.250.20
Mile (1600m)4500.400.300.20
Medium (2000m)6000.350.350.20
Long (2400m)8000.300.400.20
Extended (3000m+)10000.250.450.20

Track condition modifiers scale stamina requirements and speed efficiency. Good tracks use baseline 1× multipliers while Heavy tracks demand 50% more stamina with a 20% speed penalty.

How Race Calculation Works in Uma Musume

Understanding race performance calculation is essential for building competitive horse girls. Follow this framework to optimize your race strategy:

  1. Select race distance — Determine the distance category which sets the base stamina requirement and stat weight distribution.

Example 3: Long Distance with Closer on Soft Track

Distance: Long (2400m) | Track: Soft | Style: Closer

Speed: 550 | Stamina: 900 | Power: 600
Required Stamina: 800 × 1.3 = 1040
Stamina Sufficiency: 900 ÷ 1040 × 100 = 86.5% ⚠
Performance Score: ~71 | Solid closer build, stamina slightly low

Running Style Strategy in Uma Musume Pretty Derby

Running style is one of the most important strategic decisions in Uma Musume. Each style has distinct advantages at different race distances and stat distributions. Choosing the right style can provide up to a 10% performance bonus through synergy.

Running Style Distance Synergy

  • Front Runner (逃げ) — Best at Short to Mile distances. Requires high Speed to establish and maintain the lead. Synergy bonus on Short and Mile races.
  • Stalker (先行) — Versatile across Mile to Medium distances. Balanced stat requirements with good positioning. Synergy bonus on Mile and Medium races.
  • Mid-Pack (差し) — Excels at Medium to Long distances. Benefits from high Stamina and Power for late-race surges. Synergy bonus on Medium and Long races.
  • Closer (追込) — Dominant at Long to Extended distances. Requires massive Stamina and Power for devastating final-stretch acceleration. Synergy bonus on Long and Extended races.

Track Condition Strategy

Track conditions significantly impact race dynamics. Soft and Heavy tracks penalize Speed-focused builds while rewarding high Stamina. Yielding tracks create moderate adjustments. Always check track conditions before finalizing your race entry and adjust your strategy accordingly.

Style Synergy Bonus = 1.10 if running style matches distance, otherwise 1.00

People Also Ask About Uma Musume Race Performance

Race performance in Uma Musume is determined by a combination of core stats including Speed, Stamina, and Power, modified by race distance, track condition, and running style. Speed influences top-end velocity, Stamina determines how long a horse girl can maintain peak output, and Power affects acceleration and positioning. The interplay of these stats against race-specific modifiers determines finishing position.
The importance of stats varies by race distance. For short distances, Speed and Power are most critical for explosive acceleration. Mile races balance Speed and Stamina roughly equally. Medium distances favor a balanced stat distribution with emphasis on Stamina. Long and extended distances heavily prioritize Stamina above all other stats to prevent exhaustion before the finish line.
Stamina determines how efficiently a horse girl maintains speed throughout a race. Insufficient stamina causes significant performance drop-off in the final stretch. Each race distance has a base stamina requirement multiplied by track condition modifiers. Soft and heavy tracks demand substantially more stamina than good tracks. A stamina sufficiency above 100% ensures the horse girl can finish strongly.
There is no single best running style; the optimal choice depends on race distance and your horse girl's stat distribution. Front runners excel in short to mile distances with high Speed. Stalkers perform well in mile to medium races. Mid-pack runners thrive in medium to long distances with balanced stats. Closers are ideal for long to extended distances where high Stamina and Power create devastating late-race surges.
Track conditions apply multipliers to stamina requirements and speed efficiency. Good tracks use baseline 1× multipliers. Yielding tracks increase stamina demand by 15% with a slight speed penalty. Soft tracks raise stamina requirements by 30% and reduce speed efficiency by 10%. Heavy tracks demand 50% more stamina and impose a 20% speed reduction. Adapting running style and stat priorities to track conditions is essential for consistent wins.

Frequently Asked Uma Musume Race Questions

Yes. The calculator supports all five major race distance categories: Short (1200m), Mile (1600m), Medium (2000m), Long (2400m), and Extended (3000m+). Each distance uses specific base stamina requirements and stat weight distributions to ensure accurate performance estimates for every race type.
The performance estimates are based on community-verified formulas and cross-referenced gameplay data. While the calculator provides reliable projections, actual in-game results may vary due to RNG elements, skill activations, opponent stats, and real-time race dynamics. Use the estimates for strategic planning and add a margin for variability.
For short-distance races (1200m), prioritize Speed above all other stats with a weight of 0.45 in the performance formula. Power is the second most important stat at 0.20 weight, helping with explosive acceleration out of the gate. Stamina requirements are relatively low at 300 base, so moderate Stamina investment is usually sufficient for short races.
Absolutely. The calculator computes precise stamina requirements for every distance. For Long (2400m) races, the base stamina requirement is 800, and for Extended (3000m+) it rises to 1000. These values are further multiplied by track condition modifiers. The stamina sufficiency percentage clearly shows whether your horse girl has adequate stamina for the target race.
Running style provides a synergy bonus when matched with compatible race distances. Front Runners gain a 10% bonus on Short and Mile races, Stalkers on Mile and Medium, Mid-Pack on Medium and Long, and Closers on Long and Extended. Using a non-synergistic style applies no bonus but also no penalty to the base performance score.
Yes. Many trainers use the race calculator together with the Uma Musume Stamina Calculator for deep stamina analysis and the Uma Musume Affinity Calculator for bond optimization. Combining these tools provides a comprehensive view of your horse girl's competitive readiness across all race scenarios.
