[4] He particularly excelled in indoor racing, winning a number of medals over 800 and 1500 meters at international championship competitions.

He made his international debut at the 2005 World Youth Championships in Athletics, where he finished seventh overall in the boys' 2000-meter steeplechase.

He gradually switched from training for the steeplechase to focusing on the 800 meters, for which he qualified for the 2008 Summer Olympics.

After many years of racing as an 800-meter runner, he broke out in the 1500 meters when he ran a sub-3:40 result in the men's 1500 at the World Indoor Championships.

In February 2022, he retired from elite competitive racing and became a coach at the Dukla Prague athletics club.
