Since the 400M is 5% Aerobic and 95% Anaerobic, you need to train mostly on your Anaerobic system. First I would do some short sprints(around 50M-100M) to build raw speed needed for the start and finish of a 400M race. When you have that down, go to your local track and run some intervals ranging between 100M-400M. Running intervals will teach your body to handle lactic acid at high speeds which is needed in a 400M race(This will prevent you from dying in the last 100M).Try not to run intervals more than 400m because then the extra distance will make you end up running slower than your racing speed, which will teach your body to run slower than goal pace (not a good idea). Since their is only a 5% Aerobic part in this race, it would be a good idea to run a longer distance once or twice a week. If I were you, I would not run over 2 miles because if you run farther than that, you are then replacing the needed fast twitch muscle fibers with more slow twitch muscle which is not what you want since this is a fast event. Remember, just train hard and DON'T SLACK OFF!!!!!.
1 meter = 100 cm400 cm:= 400 cm * 1 meter/100 cm= 400 meter/100= 0.4 meterAnswer: 400 cm = 0.4 meter
its alright

Assuming you don't run any faster in the 300m. 3/4x (time run)=300m time
gettis
400 decimeters is greater than 1 meter
The men's world record in the 400 meter dash is 43.18 seconds. The men's world record in the 400 meter hurdles is 46.78 seconds. This is a difference of 3.60 seconds. The women's world record in the 400 meter dash is 47.60 seconds. The women's world record in the 400 meter hurdles is 52.34 seconds. This is a difference of 4.74 seconds.
1 metre/400 cm = 100 cm/400 cm = 1/4 or 0.25
Too slow.
45 seconds
1min 10secs should be a good time
