Summary

  • A 50-race pre-event sample on 17-18 Mar 2025, after Gran Alegria's release: Late Surger 30 firsts (4 testers, so 26 were not), End Closer 11, Pace Chaser 9, Front Runner 0, Runaway 0.
  • Dance Daiichi Ruby: 54 adoptions, 15 wins (11 non-tester). Gran Alegria: 52 adoptions, 16 wins (14 Late Surger, 2 End Closer). Durandal: 12 adoptions, 7 wins (2 non-tester).
  • Observed Late Surger average, n=30: 1901/1034/1591/1309/1354. Stamina about 700 to finish, about 900-1000 if a skill spends stamina.
  • North Flight had 24 adoptions and 3 wins in the 17-18 Mar sample. Pace Chaser winners, n=9, averaged 1874/1096/1606/1359/1390. End Closer winners, n=11, averaged 1894/968/1558/1366/1435. Budding Blossom was inherited on 24 of 30 Late winners. An earlier sample on 4-5 Mar, before Gran Alegria: Late Surger 19 firsts (5 tester), Pace Chaser 17 (3), End Closer 11 (7), Front Runner 3, and all three of those fronts were New Year Maruzensky. Bubblegum Fellow had 4 Pace wins that week and none in the later win table.

Guides: Gran + dance Ruby + support; converted End is not a universal choice.

Running styles

Styles the guides favor: Late SurgerEnd Closer

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

Result: wins or first places in room matches set up in Japan with this CM's conditions. Small samples, not Global and not a win rate in the real event.

Expected room

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.

Without one: 700.

Aptitudes: Mile S. Power is the course bonus and reaches 900 without a chase.

Measured Recommended is the observed Late Surger winner average (n=30), testers included. A forecast says stamina about 700 to finish and 900-1000 if a speed skill spends stamina or a debuff is expected. Wit 1200 or more is described as reasonable because of the downhill.

Check your own build in the HP Calculator before training: these targets come from Japanese guides.

Team compositions

  • Dance Daiichi Ruby (Late Surger) + Gran Alegria (Late Surger) + one debuffer

    From guides The largest team in a room note on the first day, and the adoption leaders of the 50-room sample.

Debuffers

Useful Legal, and both slices of the 50-room method call debuffer teams mainstream. No population win rate.

What may differ in Global

  • Pre-event sample. Testers included Dance Ruby and Durandal.
  • The final-corner gold does not belong in this build.
  • Not the December 2025 mile, where generic debuffs are off.

Gaps in the data

  • Post-event population: not found.
