call it low-12 in good weather/peak condition & low-24 for 200
add 3s to double the 200 time ( 4s for most sprinters, but mo has better endurance ) & we are getting
open 400 speed, which is about what is expected
You do not lose that much speed over 100m if you are not in full training as a distance runner
Training has more of an effect on speed endurance rather than flat out sprinting speed only an out an out srpinter would lose that much
No runner can maintain their 100m flat speed for 400m so to say that speed was what you would expect is not right
I was surprised he did not run faster than 12.98 even if the conditions were not great. That boxer managed a good time!
