In 2003, skiing history was made when Croatian siblings Janica and Ivica Kostelić became the first sister-brother duo to win World Cup Alpine slalom races on the same day.

Despite coming from a country with limited skiing facilities, the Kostelić siblings managed to make it to the pinnacle of the sport.

They would both go on to win again at the World Championships a month later - although this time a day apart.

They have been speaking to Marta Medvešek about what it felt like to chase — and achieve —their dreams together.
