Marinin was born in
Volgograd, Russia, and began skating at age four after his parents saw an advertisement for a skating school. After losing to the much younger Evgeni Plushenko, Marinin realized he would not be competitive in singles skating. Due to Marinin's height, a coach asked him to switch to
pairs and move to
Saint Petersburg. Marinin began skating pairs in 1993. He met
Tatiana Totmianina in 1995 at the Russian Nationals which he attended without a partner. They began skating together in 1996. Early in their career together, they were coached by
Natalia Pavlova in
Saint Petersburg, with choreography by Svetlana Korol. Totmianina/Marinin made consistent progress on the world scene through the late 1990s. In 1998, the pair asked
Tamara Moskvina to coach them but she was unable to take on more students and suggested 1984 Olympic pairs champion
Oleg Vasiliev. He declined due to lack of ice and connections but he accepted in 2001 when Moskvina again directed them to him. Totmianina/Marinin left Pavlova just prior to the
2001 European Championships and moved to Chicago in the United States to train under Vasiliev. They trained at the Oakton Ice Arena in
Park Ridge, Illinois. Totmianina/Marinin won their first major title at the 2002
European Championships, and went on to finish 4th at the
2002 Winter Olympics in
Salt Lake City. Twice in a row, they finished second at the
World Championships to their Chinese rivals
Shen Xue /
Zhao Hongbo, before finally winning gold in 2004. The day after winning their first World title, Totmianina suffered a dislocated shoulder in practice. They were unable to perform in the exhibition.
Accident On 23 October 2004, during the free skate at the
2004 Skate America in Pittsburgh, Marinin lost his balance while attempting an axel lasso lift and Totmianina slammed to the ice head first. She sustained a concussion and spent the night in a local hospital. On 25 October, Totmianina said that, although she felt pain, she had no memory of the accident and was not afraid to return to the ice. She recovered from her injuries rapidly and was able to return to the ice within days. Although Totmianina did not blame him, the accident weighed heavily on Marinin and when the pair returned to training, he was unable to lift her due to panic. He began seeing a
sport psychologist who helped him overcome it.
Continued career in January 2005. Totmianina/Marinin returned to competition two months later in January 2005, winning gold at the
Russian Nationals and then the
European Championships. In March, they competed at the
World Championships, held in Moscow, Russia. They won their second consecutive World title easily, with a total score 10 points higher than the second-place finishers. Totmianina/Marinin dominated world competition from that point onward. In December 2005, Totmianina was hospitalized with a gall bladder problem. They won their fifth consecutive
European Championship the following month in January 2006. With Shen/Zhao recovering from an Achilles tendon injury, Totmianina/Marinin were the clear favorites for Olympic gold in
Turin, Italy. They won the short program on 11 February and then the long program on 13 February, capturing the
2006 Olympic pair skating title. Totmianina/Marinin did not compete at the World Championships in March 2006. They later announced their retirement from competition. The pair toured with the
Champions on Ice show, with other notable skaters including
Michelle Kwan,
Evgeni Plushenko, and
Viktor Petrenko, among others. They also performed regularly in
Ilia Averbukh's ice shows in Russia, including Ice Symphony and Professionals' Cup. Marinin choreographed
Vera Bazarova /
Andrei Deputat's 2014–15 short program. He has appeared in the first seven seasons of ice show contest
Ice Age. == Personal life ==
