So last night Kenya's Ferguson Cheruiyot went out in 47.84 on his 800 leg. That's way faster than what David Rudisha ran in his WR run in London (49.28).
The question we have iis, "is that the fastest split ever for the first 400 of an 800?"
We swear there was a thread about this within the last year or two that talked about some Kenyan who crushed it for 600 but ended up running close to 2:00. However, I can't find that thread.
All I can find is this thread from 2006:

It mentions a guy at the CGs going out in 46 but no name is mentioned.
So let's decide this once and for all, "What's the fastest 400m split in an 800?"
