❝ There are no borders to quality! 13 years ago, San Isidro Columbian studfarm trusted the Haras de Semilly for the choice of his broodmares. He then cleverly combined the bloods of the best Europeans sires to produce this handsome SF sire. Let’s Go San Isidro presents a very modern, elegant, and light-boned type. He is highly blooded, with uphill, elastic gaits full of energy and elasticity. Over fences, he stands out for his reactivity and his powerful strike. He will suit preferably larger, more substantial mares, and those needing more impulsion, compared to the type that would be better crossed with his full brother Kornet San Isidro. ❞
