Hello, Elle!
It was 11a that I could not parse, then it struck me!
I had heard, or seen, 9a, before, but would not know its meaning.
Could have been a pasta dish for all I knew!
Also 27across was a problem.
Did not know the "before Christ" bit, and when I checked Chambers for what I had, it was there.
But again it was I phrase I had heard, but did not know what it applied to.
It is a good puzzle, but in 28a, the Scottish League bit is out of date, but should not affect things.
I have watched a bit of the athletics.
All going to plan for Elaine Thompson and Dafne Schippers etc, so far.
I have switched to golf just now.
Yes, it is a long day's viewing!
You are wise!
