Janneke was born as the second daughter in the family of former military rider Gert Boonzaadjer. Buitenkind Janneke could soon be characterized as ‘handy and brave’. “I used to cross a lot with my pony and so mainly came chasing by, I thought it was wonderful”, laughs Janneke, “I became attached to it from an early age and rolled in.”

At the age of 14 Janneke already switched to horses. The horse riding remained great and that is how the first European Championships in eventing among the juniors beckoned. In 2013 she became champion at the Dutch National Championships for juniors and in 2016 at the Young Riders on her own site in Renswoude. That experience only stimulated more. When Janneke also completed her Sport Marketing training in 2016, she continued full-time in horses at HC de Schalm.

Many more successes followed. She managed to put herself in the spotlight with ACSI Champ de Tailleur and was allowed to participate in the Olympic Games in Tokyo. A dream come true! After that, the dream was only further stimulated. Janneke works hard to prepare several horses for the highest level. The goal: to be there at the next European Championship, World Cup or OS and to be able to perform.

For 2019, Janneke wants to put herself in the spotlight with ACSI Campbelle WS and ACSI Champ de Tailleur at the European Championship in Luhmühlen. This is where the Netherlands must try to gain a starting ticket for the Olympic Games in Tokyo in 2020. Of course that’s the big goal in the longer term.
Janneke also hopes to be chosen to get a ticket for the World Championships for young horses in eventing in Lion d’Angers in the 7 year olds group with Halida (Saffier x Gentleman x Athlet Z)
The Dutch Championships in Boekelo is also important in 2019.

About her horses

There are some special stories about her current top horses.
“My uncle is a horse dealer, and we happened to be visiting him when we saw Campbelle”, says Janneke. “We took Campbelle home with us, because she stood out to us, and we wanted to see what sort of horse she was, and how her behaviour was under saddle. She was indeed not the most mild-mannered horse to start with, but certainly not impossible as far as I was concerned!”.
Janneke took her to an eventing competition in Portugal just two weeks later. She stopped in the first cross country, but she won the second one. “I quickly had a great bond with her! She is a typical mare, she just needs to be dealt with firmly from time to time. I’m very direct in my riding, so that suits me well.”
Bigger successes followed quickly. She won the CIC2 * in Bad Harzburg in 2016. And at the European Championships in Millstreet in 2017, Janneke and Campbelle WS won silver with the YR Team and came seventh individually.
Champ de Tailleur’s story is very different. Champ came Janneke’s way when his owner Lieke van der Werf wanted to study and had to give Champ away before she could start her course. Janneke confirms: “If Campbelle sometimes deserts you – for instance by galloping in dressage instead of extending in the trot – Champ will do anything for you. It’s sometimes sweet to see how much he wants to do his best for you. With him, I can’t be too direct, it makes him nervous. He prefers reassurance and building up. I’m very grateful to Lieke and her family that I can ride Champ. It’s great to develop my riding skills, to have these two very different types of horses!”.
