Thunderstruck, journeying from Miho, lives up to the “remarkable improvement” brief comment, showing exceptional vitality. In his final workout on January 8th, he tracked Fleccia (Steeplechase Open) from 0.2 seconds behind on the inside, ultimately finishing 0.4 seconds ahead with an impressive performance. A noteworthy detail is the effect of his equipment change: he wore cheekpieces for this workout, demonstrating an easy breakout even under pressure from both sides.

Cool Daytona

Cool Daytona recorded 4F 52.5 – 1F 12.6 on the Ritto Hill Course. As the assessment “nimble footwork” suggests, he displays sharp, energetic movements. Though his sire, Four Wheel Drive, points to a strong sprinting pedigree, his adaptability to the mile distance will be a key factor to watch.

Sound Move

Sound Move clocked an impressive 6F 83.4 – 1F 11.3 in his Ritto CW workout on January 8th. While he finished slightly behind an older horse from the 2-win class, his overall time was excellent. The assessment “no concerns about being behind” indicates he is in condition to perform above average.
