Former and banned world record holders Lashmanova, Denis Nizhegorodov and Sergey Morozov are all coached by Chegin.
[4] Banned for life in December 2012, after a second doping violation, Morozov continued to work with Chegin as an accredited Russian staff member at the 2014 IAAF World Race Walking Cup.
[5] Chegin coaches at the Centre of the Olympic training of Mordovia in Saransk, where he has been highly honored as "the father of all the victories of our race walkers.
"[6][7][8][9] He was named a "Chevalier of the Order of Glory of Mordovia"[10] As early as 2008, there were accusations of systematic doping violations on the part of Chegin.
[16] Two record breaking performances, months earlier, by Chegin coached Olimpiada Ivanova and Olga Kaniskina were not taken into account, because insufficient number of judges were present to fix them.
His replacement, Vadim Zelichenok, said “Athletes will not be allowed to work with Chegin, or otherwise they come under sanctions.”[15] On 9 November 2015, an investigative report by the World Anti-Doping Agency recommended that Chegin be given a lifetime ban from sport, due to involvement in a wide-ranging Russian doping scheme in track and field.
