The best 6y old eventer in Italy is a Sardinian mare. She is Olimpia de la Folgore (from Tenor de la Cour and Zirla), breeded by Angelo Lai and Lorella La Valle in Bonorva, a little town int the north of Sardinia.
The top-quality mare recently won the Eventing National Championship, in the category of 6 years old young horses, under the saddle of Airman Chief Andrea Cincinnati. The important competition was held in Montelibretti (province of Rome), last September.
