Eikelboom was the national and international face of Dutch endurance for the last decade. She began riding as a teenager, and took up endurance in 1995. She gradually increased her competition distances from 80 to 160km, and in 2004 was Dutch National Endurance Champion.
At the 2006 FEI World Equestrian Games in Aachen, she was one of the organizers of the support and grooming for the South African Endurance team.
She died at her farm, Katjapia, in Okahandja, where she had moved to in October last year.
She is survived by her busband, Ab van Wijk. The funeral took place on February 7, under the tree where she and Ab were married on December 21, 2007.
A memorial service will be held in the Netherlands at a later date.
