KTB Profile

Dartmouth Jet won his only start at Class 5 in the Trevor Thompson Completes All UK Racecourses Open NH Flat Race at Worcester in Sep 2025 over 1m5f – 2m on good going. The gelding has otherwise failed to add to that success in five starts since, all at Class 5. He finished 6 of 7 at Wolverhampton in Jul 2026 when last raced off his career-high mark of 59. All three runs on the all-weather have proved fruitless.

KTB Speed and Rating

KTB Speed

Best recent Speed 115 the best of the last 3 graded (A or B) runs · Worcester, 5 Sep 2025

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. What this means →

KTB Rating

Best recent KTB Rating (flat) 68C the best of the last 3 rated runs · Southwell (AW), 25 Apr 2026 Official rating 59 at the last flat run, 31 Jul 2026

Best recent KTB Rating (jumps) 118A the best of the last 2 rated runs · Worcester, 5 Sep 2025

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 — its best recent day. The KTB Rating on a racecard is a different reading of the same figures: the level the horse has been running to, an average of up to its last six runs with the latest counting most, so the two can differ. A, B or C on a run is how much known form was in that race. What this means →

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.
