re: Could you run a quarter mile in under a minute, Ocho Cincos 10 yr old did it

Here is the first result i found on the internet for 400m times

According to this you are understating the difficulty.

Here is a "List of Standards," if you may, of 400m times for an 18 year old male. Depending on your goals and background, you can use this as a rough guide to evaluate your time or set goals. To convert to female equivalents, you can add 5-6 seconds to the times on the lower end. I'm not sure if this heuristic holds true further down the list.

47 seconds--National level high school 400m runner
51 seconds--Varsity level high school runner
56 seconds--JV level high school runner
60 seconds--very solid runner, not a 400m specialist
65 seconds--above average runner, probably not on track team
70 seconds--average runner who stays in shape, or could be a good athlete who doesn't run (e.g.football player)
80 seconds--below average in either speed or endurance
90 seconds--below average in both speed and endurance or well below average in one.
