I guess I will be extremely optimistic and say 125 athletes and 10 medals
I'm curious about athletics and rowing, we have a lot of young athletes doing well in their age categories in recent years, I wonder by 2024 how many medals we can win at the Olympics, a lot will depend on how they do in the senior category the next two years. In Tokyo we won one medal in each (both were gold though).
We'll have a few chances in swimming, a few chances in shooting, a few chances in tennis as well. Probably not too unrealistic to expect one medal in each of those.
Then we also have water polo, gymnastics, sailing, wrestling, taekwondo, basketball, judo, boxing, fencing etc. Some of these sports we have good chances for 1 or 2 medals, some of sports we have small chances.
