How fast will Usain Bolt run the 800m ?

About 1:40.

All of the idiots here will be by to tell you that it’s insane to think that he would have been capable of better than 1:44. Or that he couldn’t break a 5 minute mile. So so stupid.

What do you think his 400m would have been if he had tried? 42?

How fast will it be? I'm gonna go with "DNS."

Do you have any evidence? What makes you believe a (205-210)lbs. man was capable of sub-1:48 800m? Tell us you heard or know Bolt could run 10 miles in under 60 minutes. Give us a reason to see things your way.

He ran a 2:07 in 2012

What is 9.7 times eight?

You have no concept of why he was the best at sprinting. His muscle fiber type would not allow for superior aerobic performances. It's that simple.

I agree.

And it's crazy to think that a guy capable of running 1:40 could not run close to El G's 1500 and Mile records too.

Idiots here will say that Bolt would be laughable at 5000, but you're crazy if you think somebody who could run close to 3:26 for 1500 couldn't run well under 13 minutes.

+1

1:55 if he's lucky

Dumbest post of the year

The greatest 400/800 runners are all TALL. Bolts height, stride length would be a tremendous advantage. If he trained for it he could have set untouchable world records at 400 and 800. His best chance would be some crazy split like 45-54!

21-23-25-30= 1:38

Hard to tell. His muscle fibers can take on more slow twitch-like properties. But they will still limit him somewhat. And in a sample of runners, 100 meter specialists have more of the known genes that also endurance athletes have than 400 meter runners! But at the same time we dont know how big his lung capasity can be. It may limit him or it might not. So we cannotknow

Yes we can know

There are:

Type 1 fibers

Type 2a, x, and b fibers

We are all a mix of fibers but elite sprinters have a high proportion of Type 2 B fibers. These fibers are Very high power, With a very large motor neuron, Very fast contraction time, but low mitochondrial density, low capillary density, and low resistance to fatigue. Good for less than a minute of work.

Bolt does not have the ability to compete in an event that once beyond 60 seconds is 90% in using the aerobic ATP regeneration system.

21-23-25-30= 1:38

Agreed, when you’re running that fast of splits the tenths of a second actually SUBTRACT from your time. So even though 21.0-23.0-25.0-30.0 appears to equal 1:39.0... in reality 21.3-23.2-25.5-30.2 actually gives you a finishing time of 1:38.

So Bolt really could do it. Furthermore, the Tinman pace calculator converts a 1:38 ‘800’ to 1:57:48 marathon. However, Bolt would likely have GI distress. Since he is so big he would have to drink/fuel more to maintain calorie/fluid balance. So this would slow him down to about 1:59:32. Unless of course he had Maurten energy gels. This would limit the GI distress and keep him under 1:59. *Note that all pace calculators have been adjusted to predict marathon times while the runner is wearing the 4%’s. So we don’t need to make any more adjustments... assuming Bolt doesn’t run his marathon at CIM.

You clearly don´t know what "irony" is.

Half marathon pace is 90% aerobic, so your numbers are way off.

Read my post. BEYOND 60 seconds.

Stop looking at charts that show a single race as a percentage effort for the entire effort.

The ATP regeneration is on a continuum but the early stages of an 800 are CP and Glycolytic which is perfect for a top sprinter. AFTER 60 seconds an enormous portion is aerobic.

I'm not looking at charts, and that's why I'm not writing made up numbers like you are.

So where does your information come from?

At that 60 second mark the percentages can vary based on the effort for the first portion of the race but generally someone running the 800 is going to be around 90 percent at around 60 seconds.

If your ratio is weighted towards fast twitch type b the way top sprinters are you are basically screwed in the next 40 seconds of the race. There is no getting around that. You can be tall, fit, whatever, but at that point in the race a top sprinter like Bolt becomes someone with a very big handicap. You can disagree but yoh would be wrong in doing so.
