Her father was an "excellent" football player, and she also became a footballer, playing for the South Holland team.

Van Vlerken worked in her home town for over 13 years. Her clients included school children for dance education and older people for fitness coaching. ==Athletic career==

On 13 July 2008, van Vlerken set a then new world record of 8:45:48 for Ironman-distance races at the Quelle Challenge Roth, more than five minutes faster than Paula Newby-Fraser's world record time of 8:50:53, which had stood for 14 years. The race took place in wet and cold conditions with non-stop rain and wind. Yvonne van Vlerken broke the old record with the then second-fastest female Ironman-distance marathon time of 2:54:22. Her record stood for a year, until it was again broken in Roth by Chrissie Wellington, who lowered it by 13 minutes and 49 seconds, in dry and perfect conditions. Yvonne van Vlerken's other accomplishments include: • Recorded a sub-9 hour finish (8:51:55) at her Ironman-distance debut in Roth 2007. • The only female athlete in history who has held the world record for both the half-Ironman distance (4:07:29 at 2006 Ironman 70.3 Antwerp) and the full Ironman distance (8:45:48 at 2008 Challenge Roth) == Notes ==
