Race Mechanics - Win Conditions - - Position Keep - Spot Struggle - Skill Timing - +

+ Very quick gloss of race fundamentals. Races are divided into four phases: early race, mid race, late race, and last spurt + phase. They are also divided into twenty-four equal length sections. Early race is sections 1 to 4, mid race is sections 5 to + 16, late race is sections 17 to 20, and last spurt phase is sections 21 to 24. Spot Struggle can start between 150m and the + end of section 5, and is forced to end at the start of section 9. Position Keep ends after section 10. +

+

+ The numeric value of acceleration depends on the Power stat, dueling, surface aptitude, uphills, race phase, running style. At + the start of early race, horses accelerate from 3 m/s to the early race base target speed, which varies by race + distance and running style. At the start of late race, if they have enough HP remaining for their last spurt, horses + accelerate from the mid race base target speed to their spurt speed, which varies by speed stat, distance aptitude, race + distance, running style, and guts stat, in decreasing order of effect. "Last spurt" and "last spurt phase" are different and + unrelated things; the latter is only used in the condition for Homestretch Haste. +

+

+ Speed skills add a flat amount of target speed, generally +0.15 m/s for white skills, +0.25 m/s for double circle skills and + some inherited uniques, +0.35 m/s for gold skills and most speed uniques, and +0.45 m/s for a handful of speed uniques. Accel + skills similarly add a flat amount of acceleration, either +0.1 or +0.2 m/s² for white skills and inherited uniques, or +0.3 + or +0.4 m/s² for gold skills and uniques. +

+

+ Generally speaking, competitive races are won by the horse who gets the most acceleration at the start of late race. The + consistency of front runner accel skills is what makes it a viable running style. +

Runaway +

+ The skill Runaway converts front runners into the Great Escape running style. However, no player has ever uttered + the words "Great Escape" when talking about Umamusume, presumably because Runaway is a much cooler name. +

+

+ Runaways are still front runners for most purposes, the main difference just being different base target speeds per phase. + Other mechanics that are specific to front runners also apply to runaways. +

+ Spot Struggle +

+ For each of runaways and non-runaways, there is at most one spot struggle per race. Runaways will not spot struggle with + non-runaways, nor vice-versa. When a spot struggle triggers, all front runnners of that type within range participate; I've + had a horse join while in 6th. +

+

+ Spot struggle provides a target speed bonus that scales with the guts stat. If it isn't cut short, which will approximately + never happen, its duration scales with the guts stat. Unlike skills, its duration does not scale with race distance. +

+ Position Keep +

Position Keep is the process by which pace chasers don't pass front runners in the mid race.

+

+ During Position Keep, the frontmost front runner of each type uses speed up mode to try to stay at least 4.5m (a length + is 2.5m) ahead of second place, and other front runners use overtake mode to try to become the frontmost. Both of these modes + take wit checks to enter and apply a target speed bonus for their duration; overtake mode is slightly better than speed up mode. +

+

+ Lesser running styles instead have pace up mode and pace down mode. Whether horses enter these is based on their + distance from the frontmost horse. Pace up also requires a wit check, but PDM doesn't – if a non-front horse gets too close to + the frontmost runner in the first 41.67% of the race, they are guaranteed to switch into PDM, which converts distance into HP. +

+

+ Watch a MANT late surger with 1000+ power and wit in a solo practice match. When you see her advance forward early but then + moonwalk for two seconds to the back of the pack, that's PDM. +

+

+ Converting distance into HP is quite a lot worse than just having enough HP. The fact that front runners don't have to worry + about PDM is one of their major strengths. In particular, it means that early race speed skills always gain distance for front + runners, which is not the case for the inferior styles. +

+ Skill Timing +

Thought experiment.

+

+ Picture two cars driving on a straight freeway, both at exactly 59 mph because I am American, adjacent lanes, keeping exactly + side by side. +

+

+ The one on the right then drives 1 mph faster for three seconds, creating a slight gap between them before returning to the + previous speed. They now maintain this new gap. +

+

+ There is a 65 mph speed limit sign. As each of the cars pass it, they accelerate at identical rates from 59 to 69 mph over a + duration of exactly 10.2 seconds. +

+

+ Since the car on the right is slightly ahead from the speed skill it used, it reaches the speed limit sign first, so it starts + accelerating first. +

+

+ Until the left car reaches the sign, the right car is building a speed advantage. Having a higher speed during the accel + period, it continually increases the gap it had, until both of them have reached the new target speed. +

+

+ Now the left car drives 1 mph faster for three seconds. It closes the gap between them by the same distance that the right + car's speed skill had done prior to the speed limit change. +

+

+ However, since the right car also added a distance advantage over the accel period, it remains slightly ahead of the left car. +

+

+ This thought experiment shows that speed skills are actually more valuable before late race than during it. Thus, front + runners not having to worry about PDM is even more of an advantage. +
