Running the 400m final in the Paralympics is more than likely painful enough on your body without any extra suffering.
However, the final of the T20 400m saw one Polish athlete sustain a lot of pain on her way to a bronze medal.
Polish athlete Barbara Niewiedzia took a tumble as she approached the finish line, landing on her face as she ended the race.

This pain was not suffered in vain, however, as Niewiedzia was able to claim the bronze medal for Poland.
The Polish athlete helped her country reach a total of thirty medals during this Paralympics, thirteen of which have come in athletics, with three golds, seven silvers, and a further three bronzes.
Poland are tied for the ninth most successful nation at this year's Paralympics, with three gold medals, level with South Africa, Cuba, Greece, New Zealand, Kenya, and Malaysia.
The Rio Paralympics have been far more successful thus far than first anticipated, with many warnings about poor ticket sales and funding cuts overshadowing the build up to these Games.

However, attendances have stunned the experts, as sports fans have been turning up in their droves to the majority of Paralympic events, providing spectacular atmospheres for the athletes to perform in.
The crowds have been a problem in some sports, but for a completely different reason. During the football, a sold-out 15,000 Deodoro Stadium struggled to stay quiet, hindering the performance of the footballers.
