If not team event, then give up and seek medical attention.
If team event, it's your duty to inform your team mate of your
current condition.
Because they will be the one who will help you complete the
event.
Doesn't win this competition nvm, can always train for another
6months and join another event.
No point forcing yourself and injure yourself further till you
can't run anymore.
Worse if u didn't even win in the end.
