400m strategy??

i don’t i have too do my own race and i can’t run any fast based on another person but it’s easier the last 150 if you see someone but my PR is from lane 6 when i didn’t see anyone the same indoors…

but 200 meters is at diffrent thing then i can’t run as fast the first 100 så i try too go 1-2% less the first 50m if i got lane 1.
