Sergey Marchuk


Sergey Vasilyevich Marchuk was a Russian speed skater.

Biography

In 1977, Marchuk skated 3:56.65 on the 3,000 m on the fast Medeo rink of Alma-Ata, significantly below Ard Schenk's world record time of 4:08.3. Unfortunately for Marchuk, the tournament had not been approved by the International Skating Union and so his time was not recognised as a world record. It would be 15 years before anyone, officially or unofficially, skated the 3,000 m faster than Marchuk had. This happened in 1992 when Thomas Bos skated an official world record of 3:56.16 at the indoor arena of Calgary - the Olympic Oval.
Marchuk had his best year in 1978 when he became Soviet Allround Champion, European Allround Champion, and won bronze at the World Allround Championships.

Note that Marchuk's personal record on the 1,000 m was not recognised as a world record by the ISU because he skated it at a non-approved meet. In addition, Eric Heiden skated even faster at that same meet. Marchuk's personal record on the 3,000 m was set during that same non-approved meet, so it was not recognised as a world record either. Finally, Marchuk's personal record on the big combination was not a world record either because Jan Egil Storholt skated 163.221 at that same meet.
Marchuk has an Adelskalender score of 162.996 points. He was number one on the Adelskalender for 350 days in 1977 and 1978.
