How do you convert a 300 Meter hurdle time to an expected 400 meter time?

Answer 1

52.4

Answer 2

400 meters is 99.39% of 440 yards. It's a difference of about 8 feet. So without factoring in anything but distance, clearly the biggest factor here, just take 99.39% of your 440 yard time to get an estimate of your 400 meter time.

Answer 3

There really is no conversion for times from these two races as conditioning of the athlete can dramatically change how fast the last 100m can be run. As a rule of thumb, add somewhere between 14 to 17 seconds from a 300 m time.

Answer 4

50.1 seconds

Answer 5

cut the time down by 33.3%
