Kalliopi Araouzou (swimming)
Not a big surprise because she was at the European Championships as a board member of the Greek swimming federation and not as an athlete, but she still competed until today which was her last race at the National Championships. She also struggled with injuries the past few years.
I honestly thought she would try to qualify in open water for Tokyo but I guess not. She competed in Rio in that event and finished 11th. That was her only Olympic appearance. She had two World Championship medals in open water (silver in team from 2013 and silver in 5km from 2015). She was a big part of Greek women's swimming (which the level is already quite low) for the past decade, and it's surprising that she only managed to go to the Olympics once.
She also had OST for Tokyo in 800 and 1500 freestyle but I guess she's not going to try to see if she'll get in or not. In 1500, OQT is 16:32.04 and OST is 17:01.80. She has 16:34.49 from 2019 so she was really close. Maybe she knew that there wouldn't be a spot for her in Tokyo via OST because so many people already achieved OQT in her event (I'm not too familiar with swimming qualifying procedures).
Greek women's swimming is really dead. We had 7 athletes in Beijing, 6 in London, 4 in Rio and now probably just 2 in Tokyo
