The second day of the 2019 IAAF World Outdoor Track & Field Championships is going down today in Doha, Qatar—follow along with our live updates below by refreshing this page frequently!

All times below are Central.

8:30 a.m. | Women's 100m Heats

FIRST 3 IN EACH HEAT (Q) AND THE NEXT 6 FASTEST (q)

Two-time Olympic champion Shelly-Ann Fraser-Pryce (JAM) led all qualifiers with a smoooooth 10.80 from the first heat, followed by big Qs from Murielle Ahoure (CIV) in an 11.05 season's best and Gina Luckenkemper (GER) in 11.29, who nabbed Poland's Ewa Swoboda at the line. 

Marie-Josee Ta Lou will join her countrywoman Ahoure in the semifinals as the second-fastest qualifier after an impressive 10.85 PR in heat two. She helped pull Daryl Neita of Great Britain to an 11.12 PR and an automatic qualification. Germany snuck in another qualifier in Tatjana Pinto (11.19).

The United States landed their first semifinalist in heat three as Morolake Akinosun ran 11.23 for third in heat three behind Kelly-Ann Baptiste (TTO) in 11.21 and 2016's double Olympic gold medalist in the 100m and 200m, Elaine Thompson (JAM), who didn't overly exert herself en route to a 11.14 win.

Diamond League champion Dina Asher-Smith (GBR) made quick work of heat four by throwing down a 10.96 over the second American qualifier, English Gardner (11.20), and Jamaica's Jonielle Smith (11.20). 

The return of defending world champion Tori Bowie, who battled injury for most of the past year as well as other training challenges, headlined heat five. Although she struggled to put together an 11.30, she will advance from third place as an automatic qualifier. 

All Americans will line up for the final! After bursting to the lead first, U.S. champion Teahna Daniels ran a very controlled and mature straightaway to coast through the line in 11.20. Dafne Schippers (NED) got her at the line in 11.17, but because Daniels was shutting it down to conserve her energy, knowing her semifinal spot was in the bag.

9:05 a.m. | Men's 800m Heats

FIRST 3 IN EACH HEAT (Q) AND THE NEXT 6 FASTEST (q)

U.S. champion Donavan Brazier and Canada's Marco Arop worked together to get the auto qualifiers from heat one in 1:46.04 and 1:46.12, respectively.

BREAKING: 2019's Fastest 800m Man Nijel Amos Withdraws From World Championships

Brooks Beast Brannon Kidder placed himself at the back of the pack until the final 150 meters and tried to make a move, but it was too late—Ngeno Kipngetich (KEN) got there first in 1:46.07, then Adrian Ben (ESP) in 1:46.12, and Jamie Webb (GBR) in 1:46.23. Kidder took fourth in 1:46.29, and will advance on time.

Canada's Brandon McBride took heat three in 1:45.96, followed by Qatar's own Abubaker Haydar Abdalla in 1:46.11, and 2017 world champion Pierre-Ambroise Bosse of France in 1:46.14.

Rock Chalk! 2019 NCAA champion-turned-adidas pro Bryce Hoppel advanced from heat four in second (1:46.01) behind Ferguson Cheruiyot Rotich (1:45.98). Poland's 2018 indoor world champion Adam Kszczot wound up fifth in 1:46.20. Ireland's Mark English, who blasted away from the field like a bat out of hell in an effort to control his own destiny, faded to last in 1:47.25.

Puerto Rico's Wesley Vazquez looked solid initially, but was caught at the line by both Emmanuel Korir (KEN, 1:45.16) and Mostafa Smaili (MAR, 1:45.27) to finish third in 1:45.47.

Clayton Murphy ran a smart race to finish second (1:45.62) in heat six behind Great Britain's Elliot Giles (1:45.53), who looked really good and controlled the pace from the gun. Amel Tuka was the third automatic qualifier in 1:45.62.

10:05 a.m. | Men's 400m Hurdles Semifinals

FIRST 2 IN EACH HEAT (Q) AND THE NEXT 2 FASTEST (q)

Kyron McMaster (IVB), one of the top contenders in heat one, OBLITERATED the first hurdle, sending shards of plastic flying into the air, stumbled PAST the second hurdle, and had to fight to recover, but ultimately was disqualified for skipping the second barrier. Alison Dos Santos of Brazil took heat one in a PR, 48.35, followed by 2016 Olympic bronze medalist and 2017 world silver medalist Yasmani Copello of Turkey in a season's-best 48.39.

Norway's Karsten Warholm—the fastest man in the world this year (46.92), 2019's Diamond League champion, and the defending world champion—deployed his usual race pattern of getting out HARD before beginning to cruise at around 200 meters. He won in 48.28, and Abdelmalik Lahoulou of Algeria ran a national record (48.39) for second. American TJ Holmes finished third in 48.67, and made it in on time!

Rai Benjamin vs. Abderrahman Samba in heat three! Benjamin ran comfortably for the victory in 48.52, with Qatar's Samba making up ground after the penultimate hurdle to finish runner-up in 48.72.

The final is set, along with the stage for what is shaping up to be the best race of the year:

10:45 a.m. | Men's 100m Semifinals

FIRST 2 IN EACH HEAT (Q) AND THE NEXT 2 FASTEST (q)    

Christian Coleman made a statement right off the bat in the first heat, throwing down a 9.88 despite shutting down nearly completely in the final 15 meters. Canada's Aaron Brown was the next-closest finisher in a distant 10.12 to nab the big Q. Following him, the rest of the field was extremely bunched up, finishing in 10.13, 10.14, 10.15 and 10.18—that fifth-placer was Florida's Hakim Sani Brown, running for Japan.

WOW! Some fireworks in heat two as the top three finished neck-and-neck at the line! 

Andre De Grasse (CAN) surged for the finish (10.07) and got the edge not only on a fast-starting Yohan Blake (JAM, 10.09), but also defending champion Justin Gatlin, who ended up one spot outside automatically qualifying in third (10.09)! So far, he's in good position to make it into the final, but it was surprising to see De Grasse looking more like himself after several injury-riddled years.

The third heat yielded some more drama as an extremely close finish between Mike Rodgers (USA) and Tyquendo Tracey (JAM) required the officials to review. In the middle of Rodgers' NBC Sports interview, the final results flashed onto the board to display third place: Tracey, 10.11. Akani Simbine (RSA) won heat three in 10.01, followed by Great Britain's Zharnel Hughes (10.05). 

11:15 a.m. | Women's 800m Semifinals

FIRST 2 IN EACH HEAT (Q) AND THE NEXT 2 FASTEST (q)    

Raeyvn Rogers looked impressive during her heat one victory—she opened up the half in 57.89, and held off an earnest challenge from Uganda's Winnie Nanyondo, 1:59.57 to 1:59.75. She noted that the post-race exit, which requires the track athletes to take a long set of stairs, is not ideal—especially when combined with the humidity.

The United States' Ajee Wilson stars in heat two. Without Caster Semenya and Francine Niyonsaba on the scene due to the IAAF's controversial testosterone limits on female athletes, she's the de facto favorite to claim gold in Doha. She easily took the win in 2:00.31 with Rababe Arafi (MAR) in tow (2:00.80). 

Ce'Aira Brown's wild season continues as she qualified on time (2:00.12) for the final in a bonkers semifinal that included possibly illegal contact between heat-winner Halimah Nakaayi (UGA, 1:59.35) and Eunice Jepkoech Sum (KEN, 2:00.10) during a mad dash for the finish. Brown crept up on the inside off a solid move from the final turn to punctuate a season marked by uncertainty. After an injury sidelined her for months, Brown didn't even know if she would make it to the starting line at the USATF Outdoor Championships—she returned to running just a week prior to the event, and spent the majority of her time cross-training before that. Although she didn't make the final in Des Moines, she still qualified for Worlds because Wilson earned the bye as the 2019 Diamond League champion, freeing up a fourth spot, and Brown was the only other U.S. woman with the world standard. 

Jamaica's Natoya Goule also qualified on time (2:00.33) despite the apparent interference from Nakaayi.

Noon | Mixed 4x400m Relay

FIRST 3 IN EACH HEAT (Q) AND THE NEXT 2 FASTEST (q)    

Analysis via Kevin Sully: This will be the first global championships with the mixed-gender 4x400m relay. Two men and two women will compete to see which country has the most depth in the 400m. They’ve run this event at the World Relays and it was fun. Men trying to chase down women on the anchor leg, coaches strategizing what the best order is, general relay frivolity. 

But how will it fit in a meet with more gravitas? The heats are on day two and the finals are on day three, presumably to not conflict with the open 400s or the 4x400m. It’s still hard to imagine that many of the top runners would want to race an extra 400m before the individual event. 

Further, the best individuals don’t always come from nations with the most depth, so the line-ups for the mixed-gender relay could be devoid of marquee names.  

--

In heat one, mayhem ensues! On the third handoff, what appeared to be Canada's male leg collided with Bahrain's Salwa Eid Naser—the women's open 400m favorite! No word yet on how she's doing or if she was severely affected, but it makes you question including this event at all in a world championships setting—after all, not many countries actually have the depth to put together relay squads without their best athletes, as the United States did.

Michael Johnson has some thoughts on this, too.

Mixed relay in the middle of the champs. A sport that many say already has too many events. Why? And “innovation” isn’t an answer. Innovation is only good when it works to fix a problem (this sport has many) or improves upon something.

— Michael Johnson (@MJGold) September 28, 2019

Regardless of what you think about it as a championships event, it sure can be fun—especially if you're rooting for Team USA. The red, white and blue rolled on everyone with Tyrell Richard, Jessica Beard, Jasmine Blocker and Obi Igbokwe en route to a new world record in the event, 3:12.42.

Heat two saw a bit of a strategic change from Japan, which opted to put a woman on the anchor after building a big lead, and went from first to last with 200m to go. 

1:10 p.m. | Women's 10,000m Final

Germany's Aina Reh took over after a 1:20.98 first 400m in order to quicken the pace and make things a little more honest, ratcheting the laps down to 1:15s. She took them through 1200m at 3:13. Americans Emily Sisson, Molly Huddle and Murielle Hall trailed closely behind Reh and New Zealand's Camille Buscomb. At 2400m, the field went through in 7:35, and 2800m in 8:50, holding steady at 1:15 pace.

Meanwhile, the Kenyans, Ethiopians, and the sensational Sifan Hassan laid in wait. The Ethiopian team as a whole is strong. Letesenbet Gidey, Netsanet Gudeta, and Senbere Teferi have the three fastest times of the year. Gidey has been particularly good this year and is a factor in every race she runs. 

At 3200m, that group made their move around the outside, swinging wide in a long line to overtake Reh, led by Rosemary Wanjiru and Hellen Obiri—she's better than her 31:25 PR indicates, and melds her 5000m speed with the strength that took her to a World Cross Country Championships gold medal in March.

At 3000m, Wanjiru paced the pack past the line in 11:19. Then Obiri took over through 4000m in 12:30.

That's right around when Hassan began to make her move on the front pack to claw back from no-man's land—Obiri seemed determined to put a gap on the rest of the field at that point.

After another five and a half laps, Kenya's Agnes Tirop assumed the lead, bringing the field past 5200m in 16:09, and began trading places with Wanjiru. At that point, seven competitors formed the front pack: Wanjiru, Tirop, Teferi, Obiri, Hassan, Gidey, and Gudeta, the latter of which fell off shortly afterward with 10 laps to go. 

A lap prior to that, Reh dropped out while clutching her stomach, and was carted off the track on a wheelchair—presumably due to heat exhaustion.

Through 6000m, they hit 18:36.

Sisson and Huddle, who are both in the midst of marathon training, led the back pack.

At 20:30, with eight laps to go, Obiri took over in an effort to dial up the pace. At 7000m, Obiri led them in 21:39.

Hassan continued to stalk them the back of the lead pack as they went through 7600m in 1:13, and the clock showed 24:44 through 8000m.

With a mile left at 25:59, the 21-year-old Gidey accelerated in an effort to drop Obiri, Tirop, and Hassan, throwing down a 64-second lap! Just before that, Gudeta stepped off the track.

Somehow, Hassan made up ground, and started to overcome Obiri and then Tirop! It looked like there might've been too much daylight (around 10 meters) between Gidey and the pack, but Hassan's wheels were too much! That KICK! She's got deadly speed, and perhaps Gidey knew that. She did all she could to strike out of Hassan's range, but perhaps no one can do that. 

Hassan claimed the lead at the bell lap after a 66-second lap by Gidey, and she tried to cling onto Hassan, but she was gassed! Hassan's stride enlongated down the backstretch, and around the turn, there was no question—it was all Hassan! 

Flooring it, she won gold with a sub-4:00 1500m (4:17 1600m) and put a 35-meter lead on runner-up Gidey in a 61-second-lap close for a world-leading 30:17.6!

Outstanding results for the rest of the field, too, with SIX PRs set today in the 10,000m final.

Hall was the top U.S. finisher in eighth with a 31:05.71 PR, and Huddle was close behind in ninth as Sisson closed in 10th.  

2:15 p.m. | Men's 100m Final

Ummmm, this light show, though... sick:

In the 100m final, Christian Coleman shone brighter than the light show that illuminated the track with his name during his introduction at Khalifa International Stadium.

The 23-year-old set the track ablaze en route to his first global gold with a 9.76 PR, which puts him at No. 6 all-time.

From the gun, Coleman left no doubt as he immediately burst out to a sizable lead, leaving 2017's world champion, Justin Gatlin, in the role of the hunter as he tried to claw back. 

The 37-year-old Gatlin, also a Tennessee alum, finished runner-up in 9.89. Canada's Andre De Grasse, one of the darlings of the 2016 Olympic Games, capped his season with a remarkable comeback in a 9.90 PR for bronze.

CHRISTIAN COLEMAN WORLD CHAMPION?

Coleman's victory is an accolade that affirms what we've known since 2017: the mantle of "world's fastest man" in the post-Usain Bolt 100m era rests on Coleman's shoulders. Now, he has his first world gold medal to make it official.

Two years ago, after putting together one of the greatest collegiate sprint careers ever, Coleman ventured to the IAAF World Championships for the first time, but fell short of a perfect season when Justin Gatlin overcame him in London for the win. 

Today, he fittingly turned the tables on Gatlin. While some may see it as a symbolic changing of the guard, it doesn't seem like Coleman's elder will be going anywhere as long as he's running sub-9.90s. 

Men's Long Jump Final

Jamaica earned its first medal of the 2019 world championships in this event as Tajay Gayle lept 8.69m—the longest jump in a decade!

Jamaican record AND longest wind-legal jump in the world for the last ten years...Tajay Gayle’s 8.69m is ridiculous.

Women's Hammer Throw Final

With a whopping 77.54m effort, DeAnna Price became the first American to ever win a world championships medal in the hammer throw—and she set the gold standard.

Price's winning toss capped a tremendous series at the 2019 IAAF World Championships final that saw her open up with a 76.87m effort that clinched her victory before she improved upon that distance. 

Her performance also marks the first time an American woman has ever won a throwing title at the world championships.

The 26-year-old reset her own American record earlier this season when she won her third national title the USATF Outdoor Championships with the fourth-best hammer throw in history (78.24m),

Price's journey has seen her gradually improve her placings among global competition, but this will be her first time on the podium. She finished tenth at the 2015 IAAF World Championships, eighth at the 2016 Olympic Games, ninth at her last world championships appearance in 2017, and sixth at last year's Athletics World Cup.

In an ebullient post-competition interview, she noted she wasn't even sure if she could compete this year due to injury, and struggled to throw further than 70m.

Joanna Fiodorow of Poland finished runner-up with a 76.35m PR and Zheng Wang of China took bronze (74.76m).

Price's countrywoman, Gwen Berry, unfortunately fouled out.
