"Lightning Bolt"

Because of the Earth's rotation, Usain Bolt is also the world's slowest man. It depends upon whether he's running with or against the Earth rotation.

During his career, Usain Bolt ran ˃40 times faster than a distance of 100 m and 10 sec, ˃ 29 times ran the 200 m faster than 20 sec in the official competitions.

When Bolt set the world record in the 100-m dash in 2009, he took only 41 steps which equates to 4.28 steps per sec, and an average step length of 2.44m.; his closest competitors each took 44 steps.

Usain Bolt moves at a top speed of about 6.2 body lengths/sec. Since humans walk upright, we could measure him at body depths/sec, which makes him sound faster, about 30 body depths/sec.

˃ 93 Sprinters have broken the 10-sec barrier.

Runners of West African descent are the fastest humans on earth. Remarkably, the story of East African runners is the mirror image of the West African success story. While terrible at the sprints, runners from Kenya, Ethiopia, Uganda and Somalia, along with a sprinkling of North and Southern Africans, regularly dominate endurance running.

Look at Kenya: with but 43 million people, this comparatively tiny country holds more than one third of top times in distance races. What explains this phenomenon?

The trends are eye opening: Athletes of African ancestry hold every major male running record, from the 100 meters to the marathon. Over the last seven Olympic mens 100-m races, all 56 finalists have been of West African descent. Only two non-African runners, Frances Christophe Lemaire, who is white, and Australias Irish-aboriginal Patrick Johnson, have cracked the top 500 100-meter times. There are no elite Asian sprinters or, intriguingly, any from East or North Africa.

Polish athlete Marian Jerzy Woronin. His fastest time for the 100 m was 10.00 sec, recorded in 1984 in Warsaw with wind on the maximum allowable limit of 2.0 m/s. Although Woronin's official timing read as 10.00 seconds, this was rounded up from 9.992 seconds some claim this represents the first time that a Caucasian (and a European) broke the 10-second barrier in this event.He is one of only seven individuals not of West African descent to run 100 m in 10.00 s or less the others being Koji Ito of Japan (10.00 in 1998), Australian Patrick Johnson (9.93 in 2003), Namibian Frankie Fredericks (9.95 in 1991), Zimbabwean Ngonidzashe Makusha (9.97 in 2011), Zhang Peimeng (10.00 in 2013) of China and Frenchman Christophe Lemaitre (9.92 in 2011 with a wind-assisted speed of 2.0 m/s.), who is the first person of European descent to officially break the barrier.

Lemaitre is the second white man ever to run 100 m in under 10 sec, a barrier he broke on July 9, 2010.

Bolt realises that he has broken Michael Johnson's 200m record.
Is the first person who managed to win the sprint 100 and 200 meters in two consecutive Olympics (Beijing 2008 and London 2012).

He is also looking beyond London, to the following Games in Rio. "I will definitely try a new event for 2016," he says. "Maybe the 400m or the long jump. Id like to continue to sprint but I will want to do something new, to keep it fun."

If you take the average speed of the current world 100 m record (Bolt's 9.58 s), you get about 10.44 m/s(23.35 miles/hr, 37.58 km/hr).

Royal Mail Ship (RMS) Titanic speed- Cruising: 21 kn (39�km/h; 24�mph). Max: 24�kn (44�km/h; 28�mph).

Usain Bolt also holds the record for the fastest 100 m with a running start.Segment distance of 100m - 50m from the finish and he overcame8.70 sec . This would equal an average speed of 41.38 km/h (25.71 mph). The second fastest all-time record is that of Asafa Powell, with a run of 8.75 on the 4 x 100 m anchor leg at the Beijing Olympics. Usain Bolts record was achieved at a 150 m race in Manchester May 17, 2009, completed in 14.35. Also as a result of this race, he broke the unofficial world record Pietro Mennea established back in 1983, which was equal to 14.80. After the race Bolt said: "I think it could run faster, now I'm ready to approximately 70%." Also, the athlete said that in the beginning he was a little slip distance. The race took place in the cold and rainy weather.

For Bolt, the fastest interval (60m to 80m) was run at an average speed of 44.72km/hour (27.79 mph),12.42m/s. sprinter overcame segment distance of 60 to 80 meter in 1.61 sec. In the course of the run, he overcame the first 60 meters of distance for 6.31, which is faster world record Maurice Green - 6.39.

The Fastest Farmers walk over 20 m carrying two weights of 150 kg each is 6.71 sec and was achieved by Laurence Shahlaei. Strongmen Broke Guinness World Records in Beijing. The farmer's carry event is seen in many of the strongman competitions today. For years, it has been a common event at competitions of all levels. In this case participants held a weight of 150 kg in each hand and walked in a straight line for 20 m. Mariusz Pudzianowski does it in 25:05 at the WSM 2009 (160kg each hand for 50m). Hugo Girard (Canada) 175 kg per hand on more than 25 m in 21.39 sec. On April 2011 Zydrūnas Savickas ( 4 time World's Strongest Man champion) set a new Guinness World Record performing a 20 meter Farmer's Walk in 7.55 seconds with 150 kg (330 lb) implements in each hand.

P.S.- I dont think this is regarded as a fully indoors race when in the official results You get an wind-reading� (-0.6) for this race. The roof was on the stadium, but between the roof and the stands it was openings so the wind could get into the stadium.

27.05.2010 Usain Bolt spoke at competitions Golden Spike Ostrava, his goal was to beat the higher world record Michael Johnson at a distance of 300 meters. However, the record is not destined to take place, Usain overcame the distance in 30.97, while achieving higher worlds is 30.85. Not unimportant role in the unsuccessful attempt to become cold and rainy weather

How fast Bolt might have gone had he not started celebrating 20m from the finish line back in Beijing in 2008 (9.69 ,unofficially 9.683s)? Scientists in Oslo predicted that Usain Bolt, would have run 9.60 seconds had he not celebrated prematurely in his 100m final in Beijing. The Institute of Theoretical Astrophysics at the University of Oslo, Hans Eriksen and his colleagues also predicted a sub 9.55 s time. Considering factors such as Bolt's position, acceleration and velocity in comparison with second-place-finisher Thompson, the team estimated that Bolt could have finished in 9.55�0.04s.

International Olympic Committee president Jacques Rogge condemned his chest slapping celebration as disrespectful, but Bolt insisted he was not bragging.

In the Beijing Olympic final, where Bolts reaction time was 0.165 s for his 9.69 run, the other seven finalists reacted in 0.133, 0.134, 0.142, 0.145, 0.147, 0.165 and 0.169 s. From these stats it is clear what Bolts weakest point is: he has a very slow reaction to the gun. This is not quite the same as having a slow start. A very tall athlete, with longer limbs and larger inertia, has got more moving to do in order to rise upright from the starting blocks. If Bolt could get his reaction time down to 0.13, which is very good but not exceptional, then he would reduce his 9.58 record run to 9.56. If he could get it down to an outstanding 0.12 he is looking at 9.55 and if he responded as quickly as the rules allow, with 0.1, then 9.53is the result. And he hasnt had to run any faster! A reaction time less than 0.1 s is considered a false start.

The best athletes reaction times are usually in the range of 0.12 sec to 0.16. Tim Montgomery improved that to a near perfect 0.104 sec - and came very very close to being false-started. The only sprinter to get closer to perfection was Surin Bruny - who managed a 0.101 sec in a the 1999 WC 2nd semi-final.

In the Olympic 100 m final, Bolt broke new ground, winning in 9.69 s with a reaction time of 0.165 s. This was an improvement upon his own world record, and he was well ahead of second-place finisher Richard Thompson, who finished in 9.89 s. Not only was the record set without a favourable wind (+0.0 m/s), but he also visibly slowed down to celebrate before he finished and his shoelace was untied. Bolt's coach reported that, based upon the speed of Bolt's opening 60 m, he could have finished with a time of 9.52s.

The shoe of Usain Bolt is seen untied after winning in the Beijing 2008 Olympic Games.

Reaction time is the first key factor that has been missed in assessing Bolts future potential. What are the others? Sprinters are allowed to receive the assistance of a following wind that must not exceed 2 m/s in speed. Many world records have taken advantage of that, and the most suspicious set of world records in sprints and jumps were those set at the Mexico Olympics in 1968, where the wind gauge often seemed to record 2 m/s when a world record was broken. But this is certainly not the case in Bolts record runs. In Berlin his 9.58 s time benefited from only a modest 0.9 m/s tailwind and in Beijing there was no wind, so he has a lot more still to gain from advantageous wind conditions. Many years ago, John D. Barrow worked out how the best 100m times are changed by wind. A 2 m/s tailwind is worth about 0.11 s compared to a no-wind performance, and a 0.9 m/s tailwind 0.06 s, at a low-altitude site.

So, with the best possible legal wind assistance and reaction time, Bolts Berlin time is down from 9.53 s to 9.47s and his Beijing time becomes 9.51 s. And finally, if he were to run at a high-altitude site like Mexico City, then he could go faster still and effortlessly shave off another 0.07 s. So he could improve his 100m time to an amazing 9.4 s without needing to run any faster.

Spikes-mags infographic titled "The Fastest 100m of all"?. They added up the best 10 meter splits (post-Beijing 2008) and came up with a hypothetical 100 meter time of 9.44 seconds.

Will he ever run the 100 meters in 5 seconds flat? "Not impossible," says one of the world's best known authorities on physiology and biomechanics. Professor Peter Weyand, of Southern Methodist University, known for his expertise in terrestrial locomotion and human and animal performance. Scientists believe man cant run faster than 30 mph, with the best at about 27mph.

Many prehistoric Australian aboriginals could have outrun world 100 and 200 meters record holder Usain Bolt in modern conditions. Detailed in a book by Australian anthropologist Peter McAllister entitled "Manthropology". An analysis of the footsteps of one of the fleet-footed aboriginals men, dubbed T8, shows he reached speeds of 37 kph/23mph on a soft, muddy lake edge. McAllister said that, with modern training, spiked shoes and rubberized tracks, aboriginal hunters might have reached speeds of 45 kph/ 28 mph ! "We can assume they are running close to their maximum if they are chasing an animal," he said."But if they can do that speed of 37 kph on very soft ground I suspect there is a strong chance they would have outdone Usain Bolt if they had all the advantages that he does. "We can tell that T8 is accelerating toward the end of his tracks." McAllister said it was probable that any number of T8's contemporaries could have run as fast.

The 100m sprint can be broken down into the start, acceleration and maximum speed phases, says athletic trainer Phil Davies. Sprinters have to lean forward and deliver maximum thrust to their feet during the start phase for the first 10 meters, and then slowly move the body upright for the next 50 meters during the acceleration phase, and then go into long-stride deceleration during the final 40 meters of the race.

The fastest land animal is the Cheetah which has a recorded speed of 96-120 km/h (60-75 mph) 28.3 m/s. Most Cheetahs run for only 60 seconds at a time. When sprinting, cheetahs spend more time in the air than on the ground. Cheetahs are the only species of cat who can't retract their claws.

Ethan Siegel, a theoretical astrophysicist at Lewis & Clark College, recently charted a graph to demonstrate that, judging by the incremental progression of the 100-meter world record over the past hundred years, Bolt appears to be operating at a level approximately thirty years beyond that of the expected capabilities of modern man.

Think about that. Were it not for this one freak athlete, it's very possible I wouldn't have seen the 9.6 threshold in the 100 meters broken until I was a grandfather. Since 1968, the world record has fallen about .005 seconds every 10 years. Bolt dropped it in .14 in just a year -- a 30-year advance.

Bolt is a sprinter from the future who traveled back to our time to run so fast it turns our brain into mush trying to comprehend an actual human blur.

Imagine if "Avatar" was released the same week as "Star Wars" back in 1977. That's what we're talking here. Asafa Powell and all the other world-class sprinters are "Star Wars." Bolt is "Avatar."

And Dr Peter Weyand, a leading physiologist at Southern Methodist University in Dallas and an expert on the science of sprinting, says "Bolt is a freak he defies the laws of biology."

The director of the Copenhagen Muscle Research Institute, Bengt Saltin, the worlds premier expert in human performance and race, has concluded that an athletes environment accounts for no more than 20-25 percent of athletic ability. The rest comes down to the roll of the genetic dice with each population group having distinct advantages. In other words, running success is in the genes.

Bolt and his Jamaican teammates are members of a tiny slice of the world population elite athletes who trace their ancestry to western and central Africa whose body types and physiology have been uniquely shaped by thousands of years of evolution to run fast.

Slowest run in the history of the World Championships.
Sogelau Tuvalu from Samoan represented his country at the 2011 World Championships in Athletics, achieving a mark of 15.66 sec in the 100 meters.
This result, the athlete achieved without adequate clothing for the demanding competition, because not even had spikes, is the worst recorded in the contemporary history of the sport.
Trevor Misipeka from American Samoa nicknamed "Trevor the Tortoise" weighing over 133 kg (293 lb), in the 2001 World Athletics Championships, held in Edmonton, Canada,� finished last in his 100m heat, recording a time of 14.28 seconds.

Japanese athlete from Tokyo holds the Guinness World Record for running 100 meters on all four limbs, setting a best time of 16.87 seconds at Olympic Park in Tokyo, November 2013. Ito spent nine years studying how animals like monkeys move.

Usain Bolt is the fastest man on Earth but scientists have now proven that if the 27-year-old sprinter went for a run on Titan he would literally be flying.
In a paper published in the Journal of Physics Special Topics students from the University of Leicester calculated that the nitrogen-rich atmosphere of Saturns largest moon would provide exactly the right conditions for Bolt to achieve take-off - if he was wearing a wingsuit.
On Titan the surface pressure is nearly 50 per cent stronger than Earths, meaning that the imbalance of pressure above and below the wings of Bolts (hypothetical) wingsuit would achieve lift relatively easily.
The team found that given the average wingsuit area (1.4 metres squared) any individual running above 11 metres per second would be able to take flight and as Bolt has been clocked at top speeds of 12.27 metres per second, he would be in the air before he hit the finish line in a 100 metre sprint.
Titan is seen transitting in front of Saturn. At 3,200 miles across it's bigger than Mercury.
However, as ever, there are a few meddlesome scientific facts that would bring any would-be human Concorde back to Earth with a bump.
Even if we were able to travel the roughly 1.4 billion kms to Titan, that nitrogen-rich atmosphere would have its downsides, namely a surface temperature of −179.2 �C. Bolt may be best described as "blazingly fast", but even he couldnt run in that heat.

In 1988, with no outstanding early season marks to indicate fitness, in the first race of the quarterfinals of the U.S. Olympic Trials, she stunned her colleagues when she sprinted 100 meters in 10.49 seconds, the world record. Shattering the world record by an incredible 0.17 seconds was one of the most phenomenal achievements in athletics history. Florence Griffith-Joyner's World Record has been the subject of a controversy due to strong suspicion of a defective anemometer measuring a tailwind lower than actually present. Although at the time of the race the wind meter at the event measured a wind speed of 0.0 meters per second (no wind), some observers who were present noted evidence of significant winds, and wind speeds of up to 7.0 m/s were measured at other times during the track meet. The previous race on the track was measured at +5.2, and while the second quarterfinal was also 0.0, the third quarterfinal was +4.9. It can be reasonable to assume a wind reading of about +4.7 m/s for Griffith-Joyner's quarter-final. The triple-jump anemometer, some 10 metres away, read 4.3 m/s, more than double the acceptable limit. Her 10.61 the following day and 10.62 at the 1988 Olympics would still make her the world record holder.

Since 1997 the International Athletics Annual of the Association of Track and Field Statisticians has listed this performance as "probably strongly wind assisted, but recognized as a world record". Besides this one race, Griffith Joyner's fastest wind-legal time in this sprint was 10.61 seconds, which would also be the unbroken world record. By now known to the world as "Flo-Jo", Griffith Joyner was the big favorite for the titles in the sprint events at the 1988 Summer Olympics. In the 100-meter final, she ran a wind-assisted +3m /sec. 10.54

Aside from whether her 1988 Olympic trial world record was wind-aided, Griffith Joyner was dogged by rumors of drug use.
In 1989, the athlete that was on top of the world, suddenly left the sport.
Since 1990, athletes have had serious health problems, there were heart attacks. Her husband, the Olympic champion in the triple jump Al Joyner, he caught using drugs unresolved. The sudden death of athletes from a heart attack at the age of 38 years only added to the suspicion.
In fact, according to, Joyner took and passed 11 drug tests in 1988 alone. "I know exactly what people are saying about me," she said. "And it's simply not true. I don't need to use drugs. They can come and test me every week of the year if they want to. I've got nothing to hide." Prince Alexandre de M�rode, chairman of the IOC's medical commission, later said she had been singled out for particularly rigorous testing in Seoul. "Since there were rumours at the time, we performed all possible and imaginable analyses on her," he said. "We never found anything. There should not be the slightest suspicion."
Not so easy. The problem is that Flo-Jo's improvement was just too great, her times too good. Her career as a top-level 100m runner was effectively three months and eight races long, but she still has all of the top three and five of the top 10 fastest times in history. In the 14 years since 1988 the men's 100m record has been broken 15 times; not only does Griffith Joyner's time still stand, nobody has even got close to it. Only three women have run under 10.70: Griffith Joyner, the confirmed drug cheat Marion Jones and the reigning world champion Carmelita Jeter. After she set her personal best of 10.64, still 0.15 off Flo-Jo's record, in 2009, the latter said: "Honestly the first thing I heard was 'well, she's faster than Marion and a little slower than Flo-Jo, hmmmm'."
Nothing will change now. Griffith Joyner will never fail a drug test, and she will never admit to doping. No one will strip her of her record-obliterating times, but she will also never be rid of the deep and damning fog of suspicion.

Griffith Joyner's 200m record is also emphatically unbeaten. The only person to have got within 0.30 of it since is Marion Jones. Jamaica's Veronica Campbell-Brown won 200m gold in 2004 and 2008, as well as at last year's world championships. Her personal best, 21.74, is 0.4sec slower than Griffith Joyner's at Seoul. "It is beyond my reach," she has said. She believes the continued presence of Flo-Jo's times in the record books has cheapened women's athletics. "It's disappointing to not get the respect that the males do, because they are capable of breaking the record and people are excited to see them run because they know the possibility of breaking the record is close. I don't have that luxury."

Michael Johnson, American sprinter won four Olympic gold medals and eight World Championships gold medals.
Men's 400�m race� 43.18sec ��� 26 August 1999 ��� World Championships ��� Seville, Spain -� world record time, which still remains unbeaten.
Johnson's clocking of 19.32s en route to breaking the 200 metre world record at the 1996 Olympics led some in the United States to consider him the fastest man in the world. In 1997 Johnson began appearing in Nike television advertisements in which he was billed as "World's fastest man" as a result of his 200 m world record. This was despite the fact that the 100 metres world record holder, at the time Donovan Bailey, was typically given that unofficial title.

In a much hyped competition in June 1997, he raced against Donovan Bailey in a 150-metre race at the SkyDome in Toronto. The event was unsanctioned, and its unique course consisted of 75 metres of curved track and a 75 meter straight. The race was billed as a competition for the title of "World's Fastest Man." However, Johnson failed to live up to expectations when he pulled up around the 100 meter mark after Bailey was already ahead in the race and pulling away, ostensibly having injured his hamstring. Bailey won the race and the $1.5 million prize that came with the victory, Johnson received $500,000.

Why so many marathon records are broken in Berlin?

The director, Mark Milde says there are a few key factors that make it an ideal race for breaking records.One is that "Berlin is a flat course with few corners". It starts at 38m above sea level, never gets higher than 53m or lower than 37m.

In comparison, London undulates more, twists and turns more frequently, plus runners often face a head wind when running along the River Thames past Embankment. And Boston's finish line is so much lower than its start that it is ineligible for world record attempts. Also, competitors in Berlin "run on asphalt and compared to concrete this seems to be helpful. We hear from runners that they have less problems with their joints," says Milde.

"And in late September we have running conditions that are close to ideal. There is not much wind and the temperatures are in the range of 12C to 18C." In fact the average temperature for late September when the marathon is run is 15C - which falls inside the 10C to 16C window that experts agree is the optimum temperature for a fast race.

The traditional story relates that Pheidippides (530 BC- 490 BC), an Athenian "professional-running courier" was sent to Sparta to request help when the Persians landed at Marathon, Greece. He ran about 240 km (150 mi) in 2 days. He then ran the 40 km (25 mi) from the battlefield near Marathon to Athens to announce the Greek victory over Persia in the Battle of Marathon with the word� "We have won", to then collapse and die.

(4989 km).race is the world's longest certified footrace.
The runners have 52 days in which to complete the distance - an average of 60.78 miles (97.82�km) every day. The Worldrecord is held by Madhupran Wolfgang Schwerk who broke his own time of 42 days 13:24:03 set in 2002 with a new record of 41 days 08:16:29 in July 2006.

One of the earliest multiple day races was the Trans-American footrace (then called the Bunion Derby), which took place in 1928. It began in Los Angeles and finished in New York City, covering a distance of 3,423 miles in 84 days. Coast to coast races have taken place several times since then. In 1992 a modern version of the Trans-America footrace began. Covering 2,935.8 miles from Huntington Beach, CA to New York City, the winner, David Warady, completed the distance in 521 hours, 35 minutes and 37 seconds over 64 days.

The 4 Deserts Race Series is an annual series of four 250�km (155 miles) races across desert conditions in various parts of the world.The inaugural race, the Gobi March, was run in China in 2003.

In 2004 it was the Atacama Crossing (Chile) and in 2005 it was the Sahara Race (Egypt), until in 2006 all 4 Deserts events were raced in one year with The Last Desert Antarctica being the ultimate event in the series.

Robert Garside, calling himself The Runningman, is a British runner who is credited by Guinness World Records as the first person to run around the world. Garside began his record-setting run following two aborted attempts from Cape Town, South Africa and London, England. Garside set off from New Delhi, India on 20 October 1997, completing his run back at the same point on 13 June 2003.

Garside stated that his aim was to run for his own satisfaction as well as the record, therefore he set about running each continent the longest way possible, rather than the easiest way to gain the record. His run covered around 40,000 miles across 6 continents and 29 countries.
