Stromberg won two of his first three starts on soft ground over 6f to 7f at Roscommon and Galway in 2023. Both wins came on his first visit to the course. The colt then raced five times over 1m2f to 1m4f without success and finished third of 11 in the Trigo Stakes at Leopardstown in Oct 2024 while racing off an official rating of 102. He has seven placings from nine turf runs.

KTB Speed and Rating

KTB Speed

Best recent Speed 104 the best of the last 3 graded (A or B) runs · Leopardstown, 20 Oct 2024

How fast the horse ran, as points against the day-corrected standard time for its course and distance: 100 is the median GB Class 4 handicap winner on that code; one point is 0.1% of the standard time. A, B or C is how much the day's card could tell us, not how good the run was.

KTB Rating

Best recent KTB Rating 96A the best of the last 3 rated runs · Curragh, 26 May 2024 Official rating 102 at the last run, 20 Oct 2024

What the horse achieved in each race, in pounds on the official-rating scale, from the weight carried, the lengths beaten and the race's own level solved across the archive — never the market, never the official rating as a starting point. The headline is the best of the horse's last three rated runs on that code. A, B or C on a run is how much known form was in that race.

Both figures are KTB's own, computed from the archive; no vendor rating enters either. Every run's figure is on its form line below with its grade. Grades measure how much the archive could see, never the merit of the run.
