DIRT: Champions Meeting guide

Based on Japan, not on Global

Japan already ran this CM as DIRT 2024 (Chukyo 1800) (2024-08-25 → 2024-08-31), trained in food-festival scenario. This guide summarizes what was used there and what published guides recommend.

Global can differ: cards, skills, scenarios and balance patches arrive in another order, and the meta moves with them. Check every pick against what Global has before you train for it.

Any win figure on this page, in the tables or in the notes, comes from room matches set up in Japan or from single accounts: small samples, not Global results and not a win rate in the real event.

About the CM in Japan

JP Champions Meeting of 2024-08-25 to 2024-08-31: Chukyo dirt 1800 m, left-handed, summer, sunny, Firm, day. Modelled on the Champions Cup. The late phase starts with the final corner, about 1200 m of 1800. Straight about 410 m. Track correction is stamina. Not Funabashi. Trained in the food-festival scenario. The Global English title of that scenario is not in this catalog.

Summary

No league table. A 20-race pre-event room and the guides after it put Pace Chaser in the center.
Swimsuit Hokko Tarumae is the pace ace. Copano Rickey is the partner. Debuffers were close to a default for anyone who was not one of those two.
Mile S. Stamina 901 for the track bonus. Speed cap of the scenario is cited at 1700.
That 20-race pre-event room, opponents only: Pace Chaser 62 slots and 15 wins, Front Runner 15 and 1, Late Surger 32 and 4, End Closer 11 and 0. A speed-debuffer row was 30. The counter brought a debuffer whose style is not stated, so this is not a room of 9.
One group A winner published six support cards, on King Halo, not on the horse that won the final. The final 1st was swimsuit Hokko Tarumae. Bride King Halo was 8th, with a stated 19.7% and no denominator. The six cards were wit Satono Diamond, speed Duramente, guts Orfevre, power Nishino Flower, the R friend Director Akikawa, and speed Vivlos. A self-selected poll brought swimsuit Hokko Tarumae 10 times, with 6 final firsts, and Copano Rickey 8 times, with 5.

Guides: Swimsuit Tarumae + two debuffers; alternative: Rickey as second ace.

Running styles

Styles the guides favor: Pace Chaser

Use is the share of rival Umas that ran each style in Japan: how popular it was, not how often it won.

Style	Verdict	Use in Japan	Note
Front Runner	Viable	not counted	From guides Decent when four or more fronts appear, because the pace accel does not climb back from 6th or 7th at mid-race. In 20 pre-event races the only winning Front Runner was original Maruzensky. Sample: no league-wide count
Runaway	Weak	not counted	From guides Not a winning style in the notes that were opened. Sample: no league-wide count
Pace Chaser	Best	not counted	From guides The style of the final tier. Swimsuit Tarumae and Copano Rickey. A 20-race room read the back-style wins as almost none. Sample: no league-wide count
Late Surger	Weak	not counted	From guides Mostly a rebuilt dance Daiichi Ruby, and the cost of raising dirt aptitude was called not worth it. In those 20 races the only winning Late Surger was the observer's own. Sample: no league-wide count
End Closer	Avoid	not counted	From guides Effectively absent. Sample: no league-wide count

Expected room

Front Runners per room: no source counted them. Runaways per room: no source counted them. From guides

No source counted Front Runners in a full room of 9. The figures in the style table are one graded window or a pre-event Room Match sample, not a server census.

Umas

What Japan used and what the guides recommend, one card per outfit. A recommendation is a guide author's priority, not a chance of winning.

Stats and aptitudes

Target	Speed	Stamina	Power	Guts	Wit
Recommended	1700	901	1400	1300	1200

Without one: 901.

Aptitudes: Mile S is mandatory. Pace S helps because the downhill is long.

From guides One platinum pace line is 1700/901/1400/1300/1200. Stamina 901 is the full track bonus. 867 only reaches the top speed bonus in the best condition. Not a measured winner average.

Team compositions

Hokko Tarumae swimsuit (Pace Chaser) + Copano Rickey [Eightfold☆Fortune] (Pace Chaser) + a speed debuffer
From guides The shape the final tier and the 20-race room converge on. The third name on one tier image was not in the text.

Debuffers

Useful Closer to a default than in the cups just before. A final tier said a speed debuffer in the third slot raised the win rate in those rooms for anyone who was not Tarumae or Rickey. A 20-race room saw debuffers more than double, and also said one ace plus two debuffers is not invincible. No cup-wide rate.

Measured data

Counts as their sources give them, each with its own sample. Win counts come from room matches or single accounts in Japan: small samples, not Global and not a win rate.

What may differ in Global

Swimsuit Tarumae is not in the planner roster.
The only counted sample is 20 pre-event races from one lobby.
A Korean page dates the same course to December 2025 on that server and adds no percentages.

Gaps in the data

Cup-wide win%: not found.
One tier's third name was an image, not text.
