Black Endeavour

Black Endeavour is a three-year-old who has taken a while to find the winning thread, but the pieces are starting to come together. From 10 races, this horse has crossed the line first just once — a 10% win rate, or roughly 1 win in every 10 races — but four placed efforts tell you this is a horse that competes honestly and rarely runs a stinker.Based on TrackLab's AI analysis

That sole victory came at Nottingham on 7th August 2025, and it was earned at Class 5 level, which is where Black Endeavour has done most of its racing. At that grade, the record reads 1 win from 5 races — a 20% win rate, or 1 in every 5, which is actually a solid return once you strip away the races run at higher levels where the competition was stiffer. The recent form figures — 3, 5, 6, 3, 4, 1 — tell an interesting story when you read them right to left: a win, then a fourth, then a third, then a dip to sixth and fifth, then back to third. There is ability here, but consistency is still a work in progress.

The trainer is Mark Rimell, operating out of Leafield in Oxfordshire. The yard has sent out 9 winners this season, which suggests a stable in decent health, not a powerhouse operation but one that knows how to get a horse ready to win on the right day. Black Endeavour raced just yesterday, so this is a horse very much in the middle of its campaign.

At three years old, there is still time to develop. Horses this age are often still learning what racing is actually about — settling into a rhythm, understanding what is being asked of them. The Nottingham win gives the team a blueprint: they know what works. The question now is whether Black Endeavour can reproduce that form with any regularity, or whether that August afternoon remains a high point rather than a launchpad.
