Usain Bolt opens his season running the 400m in 45.86 seconds.
I give him credit for giving an “honest effort" for the first 200 or 300 meters.
He splits 200m in 21.1 and 32.6 at 300m. His last 100m was run in 13.0.
21 flat is a very good split for elite 400 sprinters (check out splits from the 2009 World Championships).
But when your PR is 19.19, 21.1 is jogging with all that speed reserve!
