Christian Coleman, the American sprinter and member of the USA's 4x100m relay team, is confident in the team's ability to challenge and potentially break Jamaica's long-standing 4x100m relay world record of 36.84 seconds, set at the 2012 London Olympics by Nesta Carter, Michael Frater, Yohan Blake, and Usain Bolt.

Speaking after a press conference in Jamaica last week Thursday before he participated in the Jamaica Athletics Invitational on Saturday, Coleman emphasized the USA's recent relay performance of 37.40 at recent World Relays in the Bahamas, despite key athletes like himself, Fred Kerley, and Erriyon Knighton missing from the team.

A member of the USA team that ran 37.10 at the 2019 World Championships in Doha, Coleman suggested that his country’s top sprinters executing the essential elements of relay running like smoother baton exchanges, could lead to significant improvements.

"I think it's really not that difficult. It's not that hard. We make it a lot harder than it needs to be," Coleman explained. "If we just space those zones out, everybody focuses on their job, I think we have all the speed and talent to tackle that world record."

Coleman's confidence in the team's abilities underscores their ambitions for the upcoming track and field season, especially at the Olympic Games in Paris where the USA will start as hot favourites to win the gold medal.

While breaking records isn't the primary focus, Coleman believes that with proper execution and teamwork, they can challenge historic achievements like Jamaica's 4x100m world record.

With that in mind, what leg does Coleman believe is the best fit for him?

"We talk about it all the time because I feel like I can do first leg just because I know what I'm gonna do. I feel like when I do my thing, it takes a lot of the pressure off the rest of the team because I'm gonna get us out and I know when the stick is moving through that zone and second leg is going down the back-stretch and we already in the lead, everybody else can just kind of relax and just bring it home.

“But I feel if we just going in terms of trying to just run our absolute best time, I don't know if it might be suitable for me to run first leg, ‘because I feel like I'm full well capable of running any leg. I trust myself more than anybody when it comes to working the zone and getting it through. So I don't know, second, third, fourth, whatever they need me at, obviously I'm gonna do it.”

On Saturday, Coleman was fifth in the 200m in 20.46. Great Britain’s Zharnel Hughes claimed victory with a sizzling run of 19.96. The USA’s Fred Kerley was second in 20.17 with Frenchman Pablo Mateo not far behind in 20.20 for third.

Jamaica’s Roshawn Clarke is among the three finalists for the 2023 Men’s Rising Star Award, which will recognize this year's best U20 athlete at the World Athletics Awards 2023.

The other finalists are the USA’s Erriyon Knighton and Kenya’s Emmanuel Wanyonyi.

According to World Athletics, the nominations reflect some of the standout performances that the sport has witnessed this year, at the World Athletics Championships Budapest 23, World Athletics Cross Country Championships Bathurst 23, one-day meeting circuits and other events around the world.

Roshawn Clarke, 19, was fourth in World Championships 400m hurdles in Budapest in August. He equalled and then broke the world U20 record with 47.85 in Kingston and 47.34 in Budapest. Clarke is also the Jamaican champion and CARIFTA Games U20 champion.

Erriyon Knighton is the World Championships 200m silver medallist and the USA 200m champion. He also won Diamond League races in Florence and Oslo.

Emmanuel Wanyonyi is the World Championships 800m silver medallist and is the World cross country mixed relay champion. He also won Diamond League races in Rabat, Paris and Xiamen.

The winner of the 2023 Men’s Rising Star Award will be selected by an international panel of experts and be announced on World Athletics’ platforms on 11 December.

Jamaica’s Ackera Nugent and American wonderkid Erriyon Knighton are among four athletes to have their world records ratified by World Athletics.

In a release Friday, World Athletics said Nugent achieved her world U20 indoor 60m hurdles record when winning at the NCAA Indoor Championships in Fayetteville on March 13, 2021.

Other performances that were faster than the previous ratified world record of 8.00 set by Klaudia Siciarz in Torun on February 18, 2017 – including Nugent’s own 7.91 earlier in 2021 – did not fulfil all the criteria for ratification.

Nugent’s 7.92 does meet the criteria, so becomes the world U20 record.

Meanwhile, Knighton achieved his world U20 200m record at the US Championships on 26 June, running 19.69 to improve on his own previous ratified record of 19.84, also set at Hayward Field in Eugene on June 27, 2021.

Knighton had opened his season with a time of 19.49 in Baton Rouge, but that mark could not be ratified as a world U20 record because specific anti-doping testing requirements were not met.

Elsewhere, the world 10km record of 29:14 set by Yalemzerf Yehualaw in Castellon on February 27 has also been ratified.

In Castellon, Yehualaw became the first woman in history to dip under the 29:30 and 29:20 barriers on the roads, running 29:14 to improve the ratified record of 29:43 set by Joyciline Jepkosgei in Prague on 9 September 2017 and the mark of 29:38 achieved on 3 October 2021 by Bahrain’s Kalkidan Gezahegne in Geneva.

In a race held under ideal weather conditions, and with pacing assistance from Dutch distance runner Richard Douma, Yehualaw set off at a swift pace. They covered the opening kilometre in 2:51 and by 3km, reached in 8:36, Yehualaw was on target for a sub-29-minute finish.

She went through halfway in 14:28 – one of the fastest 5km clockings in history – and was still inside 29-minute pace. The Ethiopian slowed a bit during the second half, but a final kilometre of 2:52 (and a second half of 14:46) was enough to carry her to a 29:14 finish.

“I knew I had the world record in my legs and wanted to produce a challenging performance for any athletes who may attempt the record in the near future,” she said.

In March this year, Mokoka ran 2:40:13 at the Nedbank Runified 50km in Gqeberha to improve on the inaugural world 50km record of 2:42:07 that had been set by Ethiopia’s Ketema Negasa at the same event last year.

Mokoka is now the official world 50km record-holder, although CJ Albertson clocked 2:38:43 in San Francisco on 8 October, and that performance has also been submitted for record ratification.

Jamaica’s Jaydon Hibbert is among the five nominees for World Athletics’ 2022 Men’s Rising Star Award.

Shericka Jackson produced the second fastest 200m time in history to win gold in the women’s 200m final at the World Athletics Championships in Eugene on Thursday night.

Jackson, who won silver in the 100m with a 10.73 personal best on Sunday, ran a spectacular championship record 21.45 for victory ahead of teammate Shelly-Ann Fraser-Pryce (21.81) and Great Britain’s Dina Asher-Smith (22.02). Olympic champion Elaine Thompson-Herah finished seventh in 22.39.

Jackson’s time also makes her the fastest woman alive over the distance and is a new national record.

In the men’s equivalent, the USA completed their second sprint sweep of the championships with Noah Lyles defending his title from Doha with a phenomenal world-leading and lifetime best of 19.31 to become the third fastest man in history over the distance.

Kenny Bednarek ran 19.77 for the silver medal while 18-year-old Erriyon Knighton took the bronze in 19.80. The Dominican Republic's Alexander Ogando and Trinidad & Tobago's Jereem Richards were fifth and sixth in 19.93 and 20.08, respectively.

In the Women’s 800m, Jamaica’s 1500m semi-finalist Adelle Tracey ran a personal best of 1:59.20 to finish third in heat one and advance to the semi-finals.

Joining Tracey in the semis will be her Jamaican teammate and 2019 World Championships finalist Natoya Goule, who won the sixth and final heat in 2:00.06.

In the field, the world leader and defending world champion Anderson Peters of Grenada needed only one throw to advance to the final of the men’s javelin, registering a mark of 89.91m. Trinidadian 2012 Olympic gold medallist Keshorn Walcott failed to advance, finishing 16^th overall in qualifying with a throw of 78.87m.

Cuba’s Lazaro Martinez jumped 17.06m to advance to the final of the men’s triple jump.
