It’s down to the final event, with the 4x400m to go.
Here’s my understanding from Mr @csharpe:
If current leaders KC wins or comes 2nd, they win Champs regardless of where Calabar finishes. But Calabar are clear favorites with the likes of Christopher Taylor, most likely on the anchor.
If Calabar wins and KC finishes 4th or worse, Calabar wins.
If Calabar wins and KC finishes 3rd, it comes down to a tie-breaker (who wins the most medals, maybe gold medals?).
Edwin Allen has an insurmountable lead and will win Girls Championships with the final event, 4x400m to run on that side.
