Career
From a young age, Kenkhuis had a strong interest in swimming. However, by 2002, he was growing tired of the sport and close to retirement. His coach, Fedor Hes, helped him develop a different training strategy which involved spending more time on dry land.
He finished only 0.01 seconds behind the bronze medalist.
As the starting swimmer in the 4×100 meter freestyle relay, alongside Pieter van den Hoogenband, Mitja Zastrow, and Klaas-Erik Zwering he played a critical role in securing a silver medal in the event. He is a Business and Marketing major at the Johan Cruyff University in Amsterdam.
Kenkhuis was one of only eleven openly gay athletes to participate in the 2004 Olympic Games in Athens. In November 2006 he announced that he would quit swimming on the highest level after the 2006 European Championships Short Course in Helsinki, Finland.
