“He felt bad at the training camp in Muonio at the very end of October.

At some point, I saw that he really could not train, he could barely drag his legs.

And he constantly complains of weakness.

All this looked extremely strange, since the tests for COVID-19, passed by Sergey and all other athletes the day before, were negative.

The first "plus" was discovered with Ustyugov only in Moscow, when we sent him there, "Kramer said in an interview with RT.

According to him, by that time he himself understood what was happening with the athlete.

The specialist noted that Sergei's recovery was proceeding rather slowly.

“We started with very light loads, constantly making sure that the athlete's well-being did not get worse.

The first time Sergey ran at the end of December at the regional competitions and won them.

Then I started in January at the Continental Cup stage in Kirovo-Chepetsk, and only after that we decided to go to the World Cup stage in Falun.

To be honest, I didn't expect Ustyugov to run well there.

But he really managed to get in good shape by this moment, ”the coach added.

Kramer previously named the coronavirus as the top concern in his group last season.
