Jonathan Jones Runs Crazy 43.48 4x4 Split

[@joeycarter8846]

I have a hard time understanding how they can pinpoint splits so precisely, because where the runner starts from seems fluid & not precisely 400 meters.

I haven’t seen the race (would like to), but for splits 3, and 4 it is easy. You time from where the baton crosses the start/finish line in lane one at the exchange. You can use the stager lines for the 1st and 2nd legs but that is harder to do and most films never show it accurately. I get your question, but it can be done.
