# Usain Bolt Top Speed 9.58

## Introduction: What is Usain Bolt Top Speed?

This article will discuss What Usain Bolt Top Speed is. We will be drawing on research from several sources to come up with an answer to this question.

And will also explore sub-questions that may be of interest to the reader. We will also compare Usain Bolt top speed to various members of the animal kingdom.

## What is Usain Bolt top speed mph?

44.64 km/h-27.8mph

The fastest human footspeed on record is 44.64 km/h(12.4 m/s or 27.8 mph), seen during the final 100 meters sprint of the World Championships in Berlin on 16 August 2009 by Usain Bolt’s average speed between the 60th and the 80th meter, which he covered in 1.61 seconds.

According to famed writer and coach Jimson Lee at SpeedEndurance.com, Usain bolt top speed is between 60–70m, which seems to be the most accurate measurement.

[bctt tweet=”According to famed writer and coach Jimson Lee at SpeedEndurance.com Usain bolt top speed between 60–70m marks. Which seems to be the most accurate measurement.” username=”]

“According to this data, and hit his peak speed at 50m, and he then maintained this to 80m, running at about 44 km/hour.”

And the fact that he has retained both 100m and 200m golds in the Olympics cements him as a legend, a first of his kind on the track.

### What would happen if Usain Bolt top speed into you?

You receive the full weight of his body right in your face. And unlike them, you don’t wear any protective equipment.

You both risk severe concussion, and other injuries depending on impact location; on the way, you will fall on the ground which could even lead to death.

Or you might be lucky and get out of it unharmed, but that’s unlikely.

#### Is Usain Bolt top speed Faster than a Cheetah?

.

• Bolt will lose as a cheetah ran 100 meters in 5.95 seconds, but Bolt ran 100 meters in 9.58 seconds.
• Bolt ran 200 meters in 19.19 seconds, while a cheetah could sprint that distance in 6.9 seconds.

No. Usain Bolt top speed seems to be about 38km/h vs. a cheetah’s 112-120. The cheetah can also accelerate to 100km/h in about three seconds, meaning that its average even during that initial acceleration is greater than Usain Bolt top speed.

That’s not to disrespect Mr Bolt for his superb accomplishments, but a human is still a human, and cheetahs are in an entirely different league.

But if a Greyhound runs with Bolt in a 100-meter dash,

Greyhound will beat the Bolt flat as Greyhound runs 100 meters in a new record of 5.33 seconds… Awesome.

#### Can an average male gorilla run (on all fours) faster than Usain Bolt?

T cannot, but it will be close. A gorilla’s top speed is 25 MPH. Usain Bolt’s top speed is 27 MPH. If Bolt trips, however, while the gorilla is chasing him, then he’s in a world of trouble. Also, Bolt better not slow down if he knows what’s good for him.

Of course, all of this is assuming Bolt is in flat terrain with no obstacles to hinder you and not in a tropical rainforest where they usually stay :-)

#### What would happen if a tiger chases Usain Bolt?

I think it would be fun to use a scientific approach to this question.

So this is the initial scenario:

Bolt is happily walking across the grassland, thinking about when he will break his record again.

Suddenly he feels observed, turns back, and begins to peer at a tuft of grass not far away.

There, crouched, lies Billy the Bengal tiger. Billy is visible, angry, and hungry.

Usain knows exactly what he should not do, but he is too confident in his legs, and therefore he immediately starts running in the opposite direction.

Simultaneously, Billy, who was looking forward to that mistake, started galloping to pursue his new victim.

Let’s pause here and learn some useful data:

#### Billy:

.
• Maximum speed: 48–64 Km/h. Let’s pick an average 56 Km/h[1](15.56 m/s)
• Average acceleration: 4.32 m/s2
• Distance covered in a sprint: 32 m (this may be surprising, but Billy is an ambush hunter; hence he generally sprints in short bursts)
• Bonus distance: 10 m (final leap)

#### Usain Bolt Top Speed:

.
• Average speed: 37 Km/h (10.28 m/s)[3] . We will assume that he was in great shape that day.
• Average acceleration: 3.09 m/s2
• Distance covered in a sprint: Undefined and irrelevant. He can certainly sprint for way more distance than Billy.

For simplicity, we will consider Billy’s acceleration constant until the maximum speed is reached, and we will pretend that the movement is along a straight path. We will also ignore air friction and other random variables.

However, we set these rules for both competitors, so the final result’s impact should be minimal.

Now, since you have not specified an initial distance between the two runners, we can change the question to:

How far away from Billy must Bolt be in order not to become mincemeat?

and can solve this problem through the equations of motion

Specifically, Billy’s motion can be considered as a combination of two phases:

• the initial phase of uniformly accelerated motion
• the second phase of constant velocity motion.

How long do both phases last, and how much is the total distance covered?

For the initial phase, and can obtain time through this formula:

where:

• t – t0 is the time interval
• V0 is the initial velocity
• V is the final velocity
• a is the acceleration

We can replace the variables with their respective values:

Almost 3.6 seconds.

And the distance is defined by this formula:

For the second phase, we already know the distance covered (32 m), and to obtain the time, we just divide the distance by velocity (15.56 m/s), obtaining about 2 seconds.

We can conclude that Billy will cover a distance of 70 meters (28 + 32 + 10) within 5.6 seconds (3.6 + 2).

Now the next question is: how far will Bolt travel at that same time?

Needless to say, we all hope he covers a distance greater than 70 meters, otherwise…

(sorry, I couldn’t resist)

However, we can define how far Bolt should be from Billy, in the beginning, to be in a safe zone after the chase.

As Bolt’s sprint would be more irregular, with continuous accelerations and decelerations, we can consider it as constant velocity motion using an average value among all his performances (10.28 m/s). So we would use the following formula:

We need the final position to be 70 meters, and we must find the initial position, so:

from which we obtain S0 = ~ 13 meters.

Ultimately, Bolt better be more than 13 meters away from Billy if he doesn’t want to become his lunch.

It’s also interesting to note that this safety distance would be around 23 meters for a standard person.

### USAIN BOLT TOP SPEED CONCLUSION:

In Conclusion, we have noted that Usain Bolt top speed of 44.64km/h or  27.8 mp/h. Faster than any other human has ever reached.

When it comes to racing against Animals and would badly beat Bolt and an easy meal for a Cheetah, Grey Hound, or Cheetah, he would have a chance escaping from a Gorilla just about as long as it was on flat terrain. An average human would end up as a meal for a Gorilla.

### His journey started with a bet over free lunch

Once twelve-year-old Bolt and his friend Ricardo Geddes were arguing over who was the fastest runner. They decided to settle the bet with a race where the winner would receive free lunch. Bolt won the race. A local priest Reverend Nugent overheard them, and he said to Bolt that if he could beat Ricardo, he could beat anyone. And that’s how he got into sprinting.

Some other interesting facts-

• While growing up, especially in Cricket and football, he was interested in sports and is even known to have good cricketing skills, having hit Gayle and Yuvraj for sixes and even getting Gayle out bowled!

#### Sprinting:

• He is considered unusually tall for a sprinter at 6’5, and he has scoliosis, i.e., a spine bent abnormally, yet he has won 8 gold medals at the Olympics!
• He has run 100m in less than 9 seconds. In the relay split in London, this was in the men’s 4×100 meter final, which was 8.70 seconds!
• It is a misconception that he is a slow starter. In his 100-meter world record in Beijing, he covered the first 60 m in 6.29 s, which is quicker than the current world record over that distance. Link

#### Philanthropy:

• He is involved in a lot of philanthropy, supports Kenya’s wildlife conservation, and his Foundation helps local youngsters in sports.
• His sponsorship deal with Puma ensures that every year they send sporting equipment to his high school.
• His ads are filmed in Jamaica by a Jamaican production crew to boost local enterprise and gain exposure.

This ‘lightning bolt’ is truly a gentle giant!

#### World’s Fastest Man tests positive for Covid-19.

August 25, 2020

Usain Bolt self-isolates following the Covid-19 test – days after celebrating his 34th birthday at a party with no masks or social distancing in Jamaica ‘attended by guests including England star Raheem Sterling.’

• Jamaican radio says Bolt will self-isolate after testing positive for coronavirus.
• Reports say the 34-year-old received a positive result on Sunday after taking the test a few days ago.
• His birthday celebrations have involved Sterling, cricketer Chris Gayle and Bayer Leverkusen player Leon Bailey.

### Could the 100m world record potentially be even faster if Usain Bolt had dipped?

By Michael Siaw Larbi via Quora.

Definitely.

Usain Bolt missed 3 excellent chances to set a much lower world record, much much lower than the current 9.58 seconds he set at the 2009 Berlin IAAF World Championships.

Let’s take a look at these 3 otherwise perfect world record-breaking chances;

1. ### Usain Bolt BEIJING 2008 OLYMPICS

We all remember this one. Bolt’s first major Olympics (I say major because he appeared in the Athens 2004 Olympics). Bolt set a then-new World Record of 9.69 seconds (beating the 9.72 seconds he set earlier that year in New York).

Just look at the results below.

a. Bolt had the second-worst reaction time (second to Churandy Martina)

If Bolt managed to get Thompson or Dix’s reaction time of 0.133 seconds, the world record would have been sub-9.6 seconds. Who knows? Maybe better than 9.58 seconds (current world record)

b. Bolt did THIS

Yes, he did. With 20 meters (yes, you read right) to go, Bolt slowed down, opened his arms, and hit his chest (classic showboating)….and he still broke the world record!!!

Imagine if he ran full speed to the line. Maybe even 9.58 seconds would have been beaten (for sure)!

and

c. He ran like THIS

Yes. and I did not even do the guy’s shoelaces. And he still broke the World Record. Enough said. Put the above 3 situations into perfection, and I can guarantee the World Record would not have been the 9.69 seconds he ran. Maybe something 9.5-ish seconds or 9.4? Who knows?

### 2. BERLIN 2009 IAAF WORLD CHAMPIONSHIPS

In Berlin, Bolt was not in to play. No showboating this time as he did in Beijing the previous year. Tyson Gay was in the form of his life (and Bolt knew this). Bolt had to bring his A-game….and he did. Except that…

He did this

He turned around to look at where Tyson Gay was about twice (or thrice) throughout the 100m race.

If only he concentrated to the end and dipped at the line (and got Richard Thompson’s reaction time), we could have had a lower world record than this….

### 3. LONDON 2012 OLYMPICS

This event.

London 2012.

This one.

The 9.58 World Record should have (and would have) been broken here.

From the above, we can see the race had a positive tailwind of +1.5 m/s (way better than the +0.9 m/s in the 2009 world record race).

Except he did this….

Maybe you don’t get the message.

Bolt did this

That right there is called dipping for the finish line way before the finish line. With the speed at which he was running, he broke momentum….

That is how we had 9.63 seconds (a new Olympic Record) instead of a new World Record (9.50 seconds maybe?)

Usain Bolt ties 40 Yard NFL Record

Many NFL players believed they could take on Usain Bolt in the 40-yard dash.

And their actual times seem like they could for several reasons.

1) 40-yard dash times in NFL combine only start once the athlete moves, negating reaction time to the equation, which could average roughly around 0.2 seconds

2) Usain Bolt is not the best starter

3) Bolt never did an actual 40-yard dash on fairgrounds.

So here it is. Bolt runs an actual 40-yard dash in 4.22 (NFL record), is 2 years retired, in jogging pants, not even wearing cleats or football shoes. We’re not even sure if he warmed up. And I think he just wanted to have fun. Don’t mess with this guy! Hahahaha #GOAT

(From Mark Reyes, Underdog Fitness, Former University of the Philippines Coach)

Usain Bolt ties the fastest NFL 40-yard dash with a 4.22 at Super Bowl LIII. Will he run in 2020 at the #TokyoOlympics?

I was a bit more concerned at the end with the concise slow-down space he was going to tear his hamstring.

The NFL record for fastest 40-yard dash belongs to Cincinnati Bengals wide receiver John Ross, who also ran it in 4.22 seconds ahead of the 2017 NFL Draft. Former Tennessee Titans running back Chris Johnson had the previous record with a 4.24-second dash, while Dri Archer (4.26), Jerome Mathis (4.26), and Marquise Goodwin(4.27) aren’t far behind.

Auburn’s Bo Jackson claims to have run a 40-yard dash with a time of 4.13 s.A time of 4.18 run by Jackson within the same week added some support to the times’ legitimacy. Texas Tech’s Jakeem Grant was hand-timed by a New Orleans Saints scout running a 4.10 in 2016, potentially beating Jackson’s record.[9] Deion Sanders ran a 4.27-second 40-yard dash in 1989.[10]

In 2013, Carlin Isles recorded a time of 4.22 at a Detroit Lions facility during a workout.

In 2017 Olympic sprinter Christian Coleman ran a time of 4.12 seconds on turf to claim that NFL players are as fast as Usain Bolt.[12]

Usain Bolt ran a 4.22 in running shoes and a tracksuit at a promotional event for the Super Bowl in Atlanta, Georgia, on Feb 2nd, 2019.[13]

#### Usain Bolt Boasts

Sept 27, 2017

Usain Bolt feels no pressure in retirement, confident his best times can remain world records for decades. The only sprinter to capture the 100- and 200-meter track titles at three consecutive Olympics, Bolt retired last month after the world championships in London. He holds the world record of 9.58 seconds in the 100 and 19.19 in the 200 — both set in Berlin in 2009.

“I think [they’re] going to last a while,” Bolt said during a promotional event in Japan on Tuesday. “I think our era with Yohan Blake, Justin Gatlin and Asafa Powell and all these guys was the best era of athletes. If it was going to be broken, it would have been broken in this era, so I think I have at least 15 to 20 more years.” Bolt’s farewell major meet didn’t go to plan in London.

After a surprising third-place finish in the 100 behind Americans Gatlin and Christian Coleman, Bolt’s last race ended in the anguish of an injured hamstring while anchoring Jamaica’s 4×100-metre relay team. Gatlin often cast as the villain during Bolt’s long dominance, said he thinks his rival will be back. But Bolt brushed off that notion. “I have nothing to prove; that’s the main reason I left track and field. After you do everything you want, there is no reason to stick around,” Bolt said.

Bolt was the life of the party every time he competed, captivating fans with his charisma and smile. As for the next biggest star in track, Bolt said he doesn’t see anyone at the moment who he expects will follow in his footsteps.

“It’s hard for me to pick someone,” Bolt said. “I think what made me stand out was not only the fast times that I ran but my personality that people really enjoyed and loved. “If you want to be a star in sports and take over a sport you have to let people know who you are as a person, not just as a track athlete.”

Jamaica won only one gold medal in this year’s world, a disappointing haul given its success in the last decade. Bolt said his country’s young athletes will have to step up now that he’s gone. “The biggest thing with Jamaica now is if the youngsters want it,” Bolt said. “Over the years, one thing I’ve learned is you have to want to be great. If you don’t want to be great, it won’t happen.”

#### Manchester United next?

From Olympic gold to United red? Of course, wanting to be great and doing what it takes to make it happen are two different things, too. “I’ve noticed a lot of the young athletes, as soon as they get their first contract and start making money, they just don’t care as much anymore,” Bolt said. “A lot of them are satisfied with getting their first contract, going out, and making their first team. If they are satisfied with that, then we’re in trouble. “Hopefully, a few of these young guys are going to be hungry and want to be great, and if we get those guys, we will be OK, but so far, it is not looking good.”

As for the future, Bolt says he is interested in playing soccer and possibly settling down and getting married. “Something I’ve always wanted to do is play football,” said Bolt, a die-hard Manchester United supporter. “My team is working on that, but we haven’t confirmed anything yet!

#### Usain Bolt’s last 100m Race (video) (Jun 14, 2017)

Usain Bolt won his Final 100m Race in Kingston, Jamaica. The three-time Olympian (8 golds) shot to prominence in the 2002 World Juniors as a 15-year-old when he won the 200. He announced his retirement after this year’s World Championships. Bolt had never run the 100 before bursting onto the scene in 2007, breaking the New York world record. And from then, a string of world records followed in the Beijing Olympics (9.69) and London World Champs the following year (9.58).

Bolt’s goodbye run was in front of 30,000 fans.

“The run, it was just OK. I must say it was OK. I don’t think I’ve ever been that nervous running a 100m,” he said.

Bolt clocked 10.03 seconds. Despite the slow time, he said this. Bolt will

He added: “Just the atmosphere and the people, the support they came out and gave me, it was really nerve-racking.

“I never expected this, I knew it was going to be big, the stadium was ram-packed so thank you guys for coming out and supporting me.”

He added: “It’s big to see everybody that turned out. It shows that what I’ve done for the sport is a big deal to them and they really appreciate it.

“So thank you and it was my honour to put the sport of track and field at the top and to continue to dominate.

“I’ll try my best even when I’ve hung up my spikes, to really continue to push track and field in any way possible.”

Bolt’s unprecedented ‘triple triple’ of nine Olympic gold medals was downgraded to eight after Jamaican team-mate Nesta Carter, who was part of the quartet that won the 4x100m in Beijing, tested positive for a banned substance. Carter has appealed against the decision.

GENEVA (AP) — Usain Bolt has lost one of his nine Olympic gold medals in a doping case involving Jamaican teammate Nesta Carter.

The IOC said Wednesday that Carter tested positive for methylhexaneamine, a banned stimulant, in a re-analysis of samples from the 2008 Beijing Olympics.

Carter and Bolt were teammates on the winning 4×100-meter team, which set a world record of 37.10 seconds. Carter ran the opening leg, and Bolt took the baton third in a team that also included Michael Frater and Asafa Powell.

“The Jamaican team is disqualified,” the IOC said in a statement. “… the corresponding medals, medalist pins, and diplomas are withdrawn and shall be returned.”

Beijing’s relay title completed the first of Bolt’s gold medal sweeps in the 100, 200, and relay at three straight Olympics.

Bolt set world record times for all three sprint titles at the Bird’s Nest, establishing himself as the Olympic track’s defining superstar.

“I want to share it with my team,” said Bolt said after completing his hat trick in 2008. “It’s down to them that I beat the world record today. When you beat the relay world record, you feel four times happier.”

Bolt and Carter will retain their gold medals from Jamaica’s relay win at the 2012 London Olympics — in a record time of 36.84 seconds that stands today. Bolt ran the final leg on that team.

Carter and Bolt also helped lower their relay world record between the Olympic titles, taking gold at the 2011 world championships in Daegu, South Korea, in 37.04.

The 31-year-old Carter has teamed with Bolt on three straight world championship relay-winning teams from 2011 through 2015. He also took an individual bronze in the 100 in 2013 in Moscow, behind Bolt and Justin Gatlin of the United States.

Carter faces a ban from the IAAF.

Usain Bolt stated he would retire after the 2017 World Champs.

Bolt is arguably the greatest ever sprinter in Olympic History. Completed the unique tally of 9 golds, just one below the 10 counts of the Great American Sprinter/Jumper Carl Lewis. However, Lewis did it in 4 Olympic games, Whereas Bolt achieved it in just 3 Games. Beijing, 2008, London, 2012, and Rio, 2016.

Bolts’ unique triple hatrick of the 100m, 200m, and 4x100m in three successive games.

2008 Beijing –  100m 9.69(world & Olympic record), 200m 19.30 (world & Olympic record), 4×100 37.10 (world & Olympic record)

2012 London – 100m 9.63 (Olympic record), 200m 19.32, 4×100 36.84 (world & Olympic record)

2016 Rio – 100m 9.81 , 200m 19.78, 4×100 37.27

At 6’5, one of the most unique athletes we have ever seen in any sport. While the Jamaican rose to prominence in 2002 at the age of 15, winning the World Junior championships in 20.61. Hence against athletes up to 4 years older than him. Also, he went on to set the world record at 19.93 for Juniors, which still stands. While eventually moving to the 100m also, he quickly set the world records and lowered them to 9.58 at the 2009 World Championships in Berlin.

Bolt is proof that a successful junior can become a superstar as an adult if coached well in the right environment. Unlike most Caribbean athletes who decided to study in America, Bolt chose to stay and train in Jamaica.

#### Usain Bolt talks Olympic history, racing in the U.S., and more in Q&A

Nick Zaccardi

Sep 4, 2014, 11:56 AM EDT

NEW YORK — Usain Bolt made a rare appearance in the U.S. on Wednesday, about 10 days after he ended an abbreviated track season and one day after playing cricket in India.

Olympic Talk caught up with Bolt. Here are excerpts from the interview:

OlympicTalk: If you were president of the IAAF and could change one thing about track and field, what would it be?

Bolt: One thing I’d have to try to address is always going to be drug use. I will put in place to get a ban for a couple of years if you make a mistake. But if you seriously did it on purpose, you should be banned for life.

OlympicTalk: If you were president of the International Olympic Committee and could change one thing about the Olympics, what would it be?

Bolt: I don’t know. I think the Olympics is a great competition. I don’t have an issue with the Olympics. They work well.

OlympicTalk: Who do you consider the greatest Olympian of all time?

Bolt: Herb McKenley. (McKenley, the first Jamaican Olympic 100m medalist, won four Olympic sprint medals over the 1948 and 1952 Olympics.) Back in the day, these guys are my idols growing up. I live to see these guys. These guys pushed the barrier coming up and did great for Jamaica starting. I lived to see these guys and be just like them.

#### Workout routine and Diet Plan

Usain Bolt (“Lightning Bolt”) is a Jamaican sprinter and three-time Olympic gold medalist. Holding the world record for the 100 and 200-meter sprints at 9.58 seconds and 19.19 seconds, respectively, Bolt is a towering presence at 6’5″, 207lbs. Unlike the typical compact sprinter who needs 45-48 strides to cover 100 meters, Bolt only needs 40-41 strides. This lens describes Usain Bolt’s workout routine and diet plan that helped him get so fast.

#### Bolt Beaten in 400 Meter Season Opener

July 12, 2013

Jamaican Olympic sprint champion Usain Bolt was beaten in his first race of the 2013 season on Saturday, finishing third in a low-key 400-meter event in Kingston’s hometown.

The triple gold medallist from both the 2008 Beijing and 2012 London Olympics easily won his heat in 46.71 seconds at the Camperdown Classic.

But he had to settle for third place overall after his teammates Warren Weir and Yohan Blake both posted faster times in their heats.

And Weir, who finished third behind Bolt and Blake in the 200m final at London last year, won in a personal best time of 46.21 seconds.

Blake, racing in the same heat as Weir, stopped the clock at 46.64 after fading in the final straight following a blistering start.

While there was no final for the event, which was part of a Racers Track Club meeting that attracted around 30 athletes.

Bolt is the world record holder and double Olympic champion for the 100 and 200 sprints but often competes in 400 races at the start of each season to build his fitness.

Next week, he is scheduled to appear in Texas for the National Basketball Association All-Star Game, but his major goal this year is the world championships in Moscow.
