What we do know is the breeding. Mosel is by Waldgeist, a horse that won the Prix de l'Arc de Triomphe — the most prestigious flat race in Europe — and whose offspring tend to be patient, progressive types that improve as the distances get longer. The dam, or mother, is by Lope De Vega, a sire whose children have a strong record at the highest level. On paper, that is a cross designed to produce a horse that takes time to fill out and find its best, which is worth keeping in mind if the debut is a little rough around the edges.
The trainer is Joseph Patrick O'Brien, operating out of Owning Hill in County Kilkenny, and the numbers behind that name are genuinely staggering. One hundred and sixty winners already this season from one yard. To put that in context, plenty of trainers consider a dozen winners a decent year. O'Brien runs one of the most powerful operations in Ireland, and when a horse like Mosel comes out of that environment, it tends to arrive ready.
