On the breeding side, the sire Ectot is a French-bred influence with a reputation for producing horses that take a bit of time to hit their stride, so the fact that Premier Tenor is already four years old before making a debut is not unusual for this family. The dam's side traces back through Dunkerque, another French line, suggesting a horse built more for stamina than pure speed — though how that translates to the track is something only racing will tell us.
What is less of a mystery is the quality of the operation behind this horse. Dan Skelton's yard at Alcester in Warwickshire has sent out 194 winners already this season, which is a remarkable number by any standard — it means the team is producing a winner roughly every other day. Skelton has built one of the most efficient training operations in the country, and when a yard of that size and quality decides a horse is ready to run, it is usually because they have seen something at home worth following up on. That is not a guarantee of anything, but it is the strongest piece of evidence available when there is no racecourse form to lean on.
For a first-time runner with no previous results, Premier Tenor is in about as good a position as a horse can be — professional handlers, a respected breeding background, and a trainer who clearly knows how to get horses ready to perform.
