Swiss rider Nadja Minder had a great start to her Badminton debut, scoring three nines in her dressage test, across her first and last halts for a final mark of 30.3.Its unreal to be here, she said. Badminton has been my dream since childhood.Her horse, Toblerone, is the only 19-year-old in the field and looked wonderfully fresh and supple. He is a legend, she said. He was lively in the warm-up but is such a professional. He feels better now than when I got him six years ago.He hasnt had the mileage of other 19-year-old horses and we just go from show to show. Hes a machine.Toblerone is by the British-bred Yarlands Summer Song, a stallion that was eighth at Badminton in 1995 with French team rider Marie-Christine Duroy. He and Nadja were cross-country pathfinders at the European championships last year and members of the fourth-placed Swiss team.Nadja, whose mother is acting as her groom this weekend, has had training from two former Badminton winners, Piggy French (2019) and Swiss team trainer Andrew Nicholson (2017).She lives on the family farm in the Swiss Oberland. Among her hobbies is acting as groom to Swiss World Cup carriage driver Jerome Voutaz.
