A swimmer at the Invictus Games broke down in tears over a beautiful act of sportsmanship from a fellow competitor.

British athlete Sarah Robinson was struggling to finish her race on Tuesday, before compatriot and competitor Poppy Pawsey produced an incredible gesture.

Pawsey had already finished the race, but swam back to the 25-meter mark to encourage Robinson, swimming alongside her to make sure she finished, too.

After Robinson touched the wall, Pawsey pointed to her teammate and made sure the crowd commended her efforts, causing Robinson to burst into tears.
