He competed at the 2016 Summer Olympics in the 400 metres and the 4 × 400 m relay, and holds the national record (45.24) in the 400 meters, which he set at the 2019 Czech Athletics Championships.

He initially trained in the long jump, and changed to 400 m by chance, when his school team was looking for a last-minute replacement for a 400 m competition.

[6] Anas earlier broke the national 400 m record at the Polish Athletics Championships in June 2016, clocking 45.40 seconds, the exact qualification mark for the 2016 Olympics.

The quartet of Anas, Kunhu Muhammed, Ayyasamy Dharun and Arokia Rajiv clocked 3:00:91, improving their own record of 3:02.17 set four weeks earlier in Turkey.
