NAIROBI， Dec. 8 (Xinhua) -- Olympic 5，000m champion， Vivian Cheruiyot of Kenya has announced her retirement from the track to take up road running.


Cheruiyot， 33， made the stunning announcement on Wednesday night during the 2016 Athletics Kenya Gala after an illustrious career over the 10，000m and 5，000m track competitions.


"I am graduating to road racing and will not take part at next year's World Athletics Championships in London to defend my title. It is time for other upcoming athletes to fit into my shoes because I have now passed the baton，" Cheruiyot said.


Cheruiyot won for Kenya the gold medal at the 2016 Rio Olympic Games to become the first Kenyan woman to take Olympic honors in the distance， where she also won the silver medal in the 10，000m event.


During the gala， Cheruiyot was also named Kenya's Female Athlete of the year， alongside Rio Olympic marathon gold medal winner， Eliud Kipchoge， who won the Male Athlete of the Year title.


Cheruiyot made her debut in road running in September 2016 at the 36th Great North Run in Britain， which is an International Association of Athletics Federation (IAAF) half marathon competition where she notched a convincing victory.


During the race， she out-sprinted fellow Kenyan， Priscah Jeptoo， over the final 200m to register a time of 1:07.54 during her 33rd birthday.


Cheruiyot picked her third Athletics Kenya top award after she was crowned winner in 2015 for winning the women's 10，000m at the IAAF World Athletics Championships in Beijing， China after her return from maternity leave.


Commonly referred to as the "Pocket Rocket" owing to her diminutive size， the Nairobi-based police officer， with killer finishing kick， crushed her opponents during competition and for a long time was the single-most threat to Ethiopian domination of Tirunesh Dibaba and Melkamu Meserech and most recently the 10，000m world record holder， Almaz Ayana.


The pilot of the chartered plane carrying a Brazilian soccer team told air traffic controllers he had run out of fuel and desperately pleaded for permission to land before crashing into the Andes [url=http://www.cheapnflbuccaneersjerseys.com/patrick-murray-jersey/]Patrick Murray Buccaneers Jersey[/url] , according to a leaked recording of the final minutes of the doomed flight.


In the sometimes chaotic exchange with the air traffic tower, the pilot of the British-built jet could be heard repeatedly requesting authorization to land because of "fuel problems." A female controller explained another plane had been diverted with mechanical problems and had priority, instructing the pilot to wait seven minutes.


As the plane circled in a holding pattern [url=http://www.cheapnflbuccaneersjerseys.com/chris-baker-jersey/]Chris Baker Buccaneers Jersey[/url] , the pilot grew more desperate. "Complete electrical failure, without fuel," he said in the tense final moments before the plane set off on a four-minute death spiral that ended with it slamming into a mountainside Monday night.


Just before going silent the pilot said he was flying at an altitude of 9 [url=http://www.cheapnflbuccaneersjerseys.com/t-j-ward-jersey/]T.J. Ward Buccaneers Jersey[/url] ,000 feet and made a final plea to land: "Vectors, senorita. Landing vectors."


The recording, obtained Wednesday by Colombian media [url=http://www.cheapnflbuccaneersjerseys.com/ali-marpet-jersey/]Ali Marpet Buccaneers Jersey[/url] , appeared to confirm the accounts of a surviving flight attendant and a pilot flying nearby who overheard the frantic exchange. These, along with the lack of an explosion upon impact, point to a rare case of fuel running out as a cause of the crash of the jetliner [url=http://www.cheapnflbuccaneersjerseys.com/donovan-smith-jersey/]Donovan Smith Buccaneers Jersey[/url] , which experts said was flying at its maximum range.


For now, authorities are avoiding singling out any one cause of the crash, which killed all but six of the 77 people on board [url=http://www.cheapnflbuccaneersjerseys.com/noah-spence-jersey/]Noah Spence Buccaneers Jersey[/url] , including members of Brazil's Chapecoense soccer team traveling to Medellin for the Copa Sudamericana finals — the culmination of a fairy tale season that had electrified soccer-crazed Brazil.


A full investigation is expected to take months and will review everything from the 17-year-old aircraft's flight and maintenance history to the voice and instruments data in the black boxes recovered Tuesday at the crash site on a muddy hillside. The U.S. National Transportation Safety Board was taking part in the investigation because the plane's engines were made by an American manufacturer.


As the probe continued, mourning soccer fans in Medellin and the southern Brazilian town of Chapeco, where the team is from [url=http://www.cheapnflbuccaneersjerseys.com/vernon-hargreaves-iii-jersey/]Vernon Hargreaves III Buccaneers Jersey[/url] , were converging on the two cities' soccer stadiums for simultaneous candlelight vigils. The six survivors were recovering in hospitals, with three in critical but stable condition, while forensic specialists worked to identify the victims so they could be transferred to a waiting cargo plane sent by the Brazilian air force to repatriate the bodies.


Alfredo Bocanegra [url=http://www.cheapnflbuccaneersjerseys.com/kendell-beckwith-jersey/]Kendell Beckwith Buccaneers Jersey[/url] , head of Colombia's aviation agency, said that while evidence initially pointed to an electrical problem, the possibility the crash was caused by lack of fuel has not been ruled out. Planes need to have enough extra fuel on board to fly at least 30 to 45 minutes to another airport in the case of an emergency [url=http://www.cheapnflbuccaneersjerseys.com/chris-godwin-jersey/]Chris Godwin Buccaneers Jersey[/url] , and rarely fly in a straight line because of turbulence or other reasons.
