The wheelchair racer was part of a thrilling Thursday for his nation which notched three golds in the space of an hour.

Catherine Debrunner and Manuela Schär struck gold before Hug took centre stage, winning the men's 800 metres F54 final in 1min 33.68sec.

The victory completed a memorable hat-trick for both Switzerland and Hug who has also achieved gold-medal success in the men’s 1500m T54 and 5000m T54 in the Japanese capital.

Hug will now be looking to defend his men’s marathon T54 crown as he eyes a fourth gold in Tokyo and the sixth of his career.

"I have so many emotions, it is just incredible what is happening right now," said the 35-year-old.

"I am in a very good shape, everything works so great, mentally as well.

"We have had a great day with two more golds and a bronze.

"We have great support in Switzerland, especially the wheelchair athletes, and great support in Nottwil [training base].
