i am a 19 yr. old mid-distance runner that aims to shift focus on the 400m. My long term goal (5 yrs.) is to qualify for the Olympic trials for Paris 2024 in the 400m. My progression in the 400m is 1:01.2 (2017) -> 55.3 (2018) -> 50.49 (2019). Assuming the trials standard is the same for Tokyo and Paris, do you think it's possible to hit the standard of 44.90 by 2024?
