I was talking to my brother while watching the match. He watches football at times, and I just mentioned, "hey, to score a single point, both players ran about as far as a single football field"
It would be interesting to see how many feet they moved for the entire game. It's so crazy to consider how small the court is, but how much you have to move for each game!
Although, one thing to note about game length is that the commentator's noted that the umpires weren't very picky about enforcing the time limit rules (time between points, etc.). That probably made the games a bit longer, but I don't think it's a terrible thing especially with how long the games last overall!
