Career
Schenk competed in international meets from 1964 on, winning his first medal at the 1965 world championships and his first gold medal at the 1966 European championships. In the late 60s, Schenk was usually bested by his compatriot Kees Verkerk, but in the early 1970s he dominated international speed skating. The winning duo of Ard & Keesie were responsible for a lasting popularity of speed skating in the Netherlands.
Schenk"s career peaked in 1972.
The next season (1973), he turned professional with a number of other prominent speed skaters, thereby foregoing the opportunity of winning more championships. The professional circuit lasted two seasons and Schenk retired from speed skating at the relatively young age of 30.

World records
Schenk was the first to skate the 10000 meters under 15 minutes, and the first skater to finish the 1500 meters in less than 2 minutes. Over the course of his career he broke a total of 18 (senior) world records, a feat no skater before or after him has bettered.
Among men, the sprint specialist Jeremy Wotherspoon came closest with his 16th world record in 2007, while among women long-distance specialist Gunda Niemann equalled Schenk"s mark in 2001.
By March 1971, Schenk held 6 of the 7 official world records at the same time, missing only the 500 m. His 1000 m record was broken in March 1972 by Erhard Keller, but the other five stood until 1975 to 1978, when world records started to be skated at the high-altitude rink of Medeo.

Personal records
To put these personal records in perspective, the column WR lists the official world records on the dates that Schenk skated his personal records, and, since the world records he broke were often his own, the column AE lists the best times skated by anyone else up to those dates.
Schenk has an Adelskalender score of 166.241 points.
He was number one on the Adelskalender from 13 January 1966 until 27 February 1967 and again from 13 February 1971 until 19 March 1976 for a total of 6 years and 58 days. The Adelskalender is an all-time allround speed skating ranking.
