On 14 June 2010, the event organizers announced that 144 athletes from 30 countries have entered the championships.
Almost 1000 athletes enter the senior men's and women's race which has been held every year since 1988.
All 45 nations' athletes entered the stadium after the show's end.
The heats were held on 29 July 1976 and 45 athletes entered.
More good athletes from remote nations enter sports that were not open to them.
After all the athletes enter the stadium, the final medals ceremony of the Games is held.
The athletes, for the first time, entered the stadium as national teams, marching behind their flags.
Because six other athletes had entered but chose not to run, none in the group was eliminated from the second round tonight.
The charter provides that no more than three athletes per country may enter a track and field event.
And Georgia's athletes enter the arena without any mention of what's going on.
