Sjaak Sleiderink made a great start on the first day of CSIYH1* in Valkenswaard with his quality horse Glamour (Numero Uno x Iroko). They jumped a fast, clear round in this two phases course which led them to the second prize. The next day Sjaak and this Numero Uno-mare improved this result by winning the 1m30 class for 6yo. At the beautiful Tops International Arena this combination showed a lot of potential.
