U S S Constitution

There is a horse that rarely wins but has quietly become a study in consistency — and the occasional well-timed strike. U S S Constitution has won just 2 races from 24 outings, a win rate of roughly 1 in every 12, but that bald number only tells part of the story. With 4 places added on top, this six-year-old has been competitive far more often than those headline figures suggest, and it is still very much in the thick of things, having raced just yesterday.Based on TrackLab's AI analysis

Auto-Generated

The distance bracket of 7 furlongs to a mile is clearly where this horse is at its most dangerous. In those 7 races at that trip, it has won twice — a win rate of 29%, or nearly 1 in every 3 — which is a dramatically better record than its overall career figures imply. That tells you something important: put U S S Constitution at the wrong distance and you are probably wasting your time, but get the trip right and you are looking at a genuinely different animal. The first career win came at Royal Ascot's home track in September 2022, which is a course with more prestige per furlong than almost anywhere in British racing. The most recent win arrived at Kempton Park in February 2026, showing the ability is still there.

Recent form reads 5-3-–-1-10-7, which is a mixed picture. A win and a place sit in among some quieter efforts, and the blank suggests a non-finish at some point. But the third-place finish and the win are recent enough to show this horse has not gone away.

Ed Walker trains out of Upper Lambourn in Berkshire, one of the heartlands of British racing, and his yard has been in strong form this season — 75 winners is a healthy total that puts them firmly in the productive tier of training operations. A horse trained by someone sending out that volume of winners is not being neglected; it is part of a functioning, well-run string. At Class 6 level — the entry-level tier of British flat racing — U S S Constitution has won 1 from 3, a solid 33% win rate, suggesting that when the conditions and the company are right, this horse knows how to get the job done.
