Sergey Vasilyevich Marchuk was born on April 13, 1952, and died on August 25, 2016.
He was a Russian speed skater.
During 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 (ISU) and so his time was not recorded as a world record.
It would be 15 years before anyone, officially or unofficially, skated the 3,000 m faster than Marchuk had.
After 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.
He had his best year in 1978 when he became Soviet Allround Champion, European Allround Champion, and won bronze at the World Allround Championships.
Sergey Marchuk passed away at 64 years old.
