One of the quickest and oldest 40 yard dash predictor for 400 meter talent (or any sprinting distance) is running a 40 yard dash. Then,
- For Male athletes = (Time for 40 yards × 10) + 2 seconds
- For Female athletes = (Time for 40 yards × 10) + 4 seconds
Thus, for a man, a 4.6 40 yard dash is (4.6 seconds x 10) + 2 = 48.0
Now, it’s not saying that a 4.6 40 yard guy WILL run 48 flat for 400m, though funnily enough, my 40 yard dash was 4.6 and I ran 48.36.
It’s saying a 4.6 40 yard dash has the POTENTIAL of running 48 seconds for 400 meters based on raw speed.
As Jared Deacon nicely pointed out, speed is the key… your 400m is based on your 200 time, your 200m is based on your 100 time, your 100m is based on your 60 time, your 60m is based on your 30 time. Or 40 yard or 36.6 meters.
