In what sport would neither the Competitors or the spec taters?

Question

know the score till the end of the game.

Answer 1

Archery

Answer 2

Cross Country running

The score is a cumulative total of the top finishers for each team. so until each team has had at least 5 members of their team finish the score is unknown..

Track
Points for each event based on 1st - 5th place (usually) for an overall team total..so until the meet is over the score is really an unknown.

Answer 3

I'd say horseracing (or track and field, swimming, any race-type sport, etc.) because the "game" is each race and the results aren't known until it's over.
