Depends honestly. 21 low is kinda too fast for a 45. Most 43’s are run with a 20.5-20.9 first 200. 21 low is a 44 low to 44 high potential if they can hold it. To run 45 optimally you’d wanna come in at 21 mid to 21 high and then come home in 23 flat to 23.5 ish
@@TrackStar42 The only two 45s run this year have been done with a 21 low split. Not saying 21 mid to 21 high is the wrong way to go about it, I'm saying that 21 low just seems to be more popular.
If slower there's a big chance you don't get the lead out on the 2nd lap and from there you might need to spend that extra energy to pass opponents anyway. Indoor running is definitely different in this regard.
21 low seems to be the go to 200 split time if you wanna run a 45.
and 23low to break 50...
