Three days of track and field action are done at the Paris Olympics, eight more are to go. 

Last night's finals were a thrilling reminder that anything can happen during the biggest meet of the year, from a magical women's 100 meter final to an epic closedown in the final straightaway during the mixed 4x400 relay.

Sunday's action will include 400 meter men's rounds, the women's high jump and men's hammer finals, the women's 800m and men's 1,500m semifinals and then the conclusion of the men's 100 meter final. 

The night will finally provide us with an answer to the question we've all been wondering. Who's the fastest man in the world? 

Better yet, who's the fastest man in the world when it matters? 

Check below for live updates from Sunday's evening session.

2024 Olympic Track And Field Live Updates, Sunday, Aug. 4 -- P.M. Session

12:55 p.m. EST -- Women's High Jump

Yaroslava Mahuchikh, the world record-holder from Ukraine, scored the Olympic win with a clearance of 2.00 meters even on Sunday, doing so on her first attempt. 

Australia's Nicola Olyslagers also cleared 2.00m, though it came on her third attempt, which pushed her to second overall. 

Mahuchikh's countrywoman, Iryna Gerashchenko, was third with a height of 1.95m.

1:05 p.m. EST -- The Men's 400m First Round

We have six qualifying heats and three athlete through to the next round in each section here. 

Section one featured the world's fastest man at the distance, Great Britain's Matthew Hudson-Smith, and he won in 44.78, followed by the U.S.'s Chris Bailey, who was second in 44.89. There may have been questions about how Bailey would respond at the Olympics after qualifying at the Trials, but he answered them firmly in the first round. 

Then came heat two. And what a statement from Michael Norman. 

The American ran the fastest 400m of his season here in 44.10 seconds, clocking a top 10 world time and winning the heat. Trinidad & Tobago's Jereem Richards was second in 44.31.

The U.S. champion at the Trials, Quincy Hall, won the fourth heat in 44.28 while Kirami James of Grenada -- a former Olympic champion -- took heat five in 44.78. NCAA champion Christopher Morales-Williams also pushed through and finished second in the heat in 44.96.

Great Britain's Charles Dobson won the sixth heat in 44.96,  while Alexander Doom -- a possible medal contender -- was second in 45.01.

1:30 p.m. EST -- Men's Hammer Throw

It only took one throw for Canada's Ethan Katzberg to pick up his first Olympic victory. 

On his first throw, Katzberg threw 84.12 meters. He was the only athlete on Sunday to produce a mark over 80 meters. 

Hungary's Bence Halász was second with a mark of 79.97m, while Ukraine's Mykhaylo Kokhan was third with a throw of 79.39m.

2:05 p.m. EST -- Men's 100 Meter Semifinals

Section One -- 

Ooo, baby, what a first heat. 

One of Jamaica's top medal threats, Oblique Seville, looked to his left over the final meters as he crossed the line to beat American Noah Lyles in the section in a time of 9.81 seconds. 

That performance was a new season best for Seville and settled past Lyles, who followed in 9.83 seconds. Great Britain's Louie Hinchliffe, who beat Lyles in the opening round yesterday, was third in 9.97 and will need to wait to see if his time gets him into the final. 

The top two advance from the top three sections, while the next three fastest times are through. 

Section Two -- In a stacked field, something had to give. South Africa's Akani Simbine powered through the finish in a winning time of 9.87, followed by Botswana's Letsile Tebogo. Needing some help, however, were defending Olympic champion Marcell Jacobs of Italy and American Kenny Bednarek, the pair finishign in 9.92 and 9.93. 

One more heat to go. 

Section Three -- 

Is Kishane Thompson the leading force to win an Olympic gold at this point? 

The Jamaican wins the third heat in a leading time of 9.80, and he shut down with 10 meters left. He gave a cursory glance over at Fred Kerley, who gave a cursory glance back! 

Kerley has to be happy with the performance. A year after failing to make it out of the semifinals at the World Championships, the defending Olympic silver medalist is through to the finals with his 9.84 performance. 

The eight men through to the men's 100m final: Kishane Thompson (9.80), Oblique Seville (9.81), Noah Lyles (9.83), Fred Kerley (9.84), Akani Simbine (9.87), Letsile Tebogo (9.91) Marcell Jacobs (9.92) and Kenny Bednarek (9.93).

First athletes out? South Africa's Benjamin Richardson (9.95), Hakim Sani Brown (9.96), Louie Hinchliffe (9.97) and Andre De Grasse (9.98).

The defending World Championship bronze medalist Zharnel Hughes struggled over the third heat and finished in 10.01.

2:35 p.m. EST -- Women's 800m Semifinals

Heat One -- 

Natasha Goule-Toppin wasted little time setting the tone here. 

The Jamaican pressed on the field an early pace -- 58.4 seconds through the first 400 meters -- and led through 600m, but she wasn't necessarily in complete control. 

Just past the final curve, Kenya's Mary Moraa inserted herself into the equation and took over, finishing the race with the win in 1:57.86. Positioning make a major difference for Moraa, who won the World Championship last year, and it enabled her to free from the pack over the straightaway. 

Ethiopia's Worknesh Mesele followed and left Goule-Toppin behind, finishing in 1:58.06. Those two were the automatic qualifiers over the first heat.

Cuba's Daily Cooper Gaspar and 17-year-old Phoebe Gill of Great Britain were third and fourth overall in 1:58.39 and 1:58.47, respectively. 

Heat Two -- 

A case example of how things can change in a heartbeat. 

Great Britain's Jemma Reekie was commanding this race ...until she wasn't. Somehow, Reekie did not have enough in the tank over the final meters and she was left by six other competitors, finishing fifth overall in 1:58.01, which leaves her out of the final. 

Reekie led the field through the first 400m in 56.7, but as the field kept on and then found another gear over the final 120 meters, things started to change quickly. 

Ethiopia's Tsige Duguma claimed the section in 1:57.47, giving the country two countrywoman in the final. Shafiqua Maloney of St. Vincent hammered her final 100 meters with impressive fashion to finish second in 1:57.59. 

And then there was American Juliette Whittaker. She was in great position, then lost contact with about 150 meters to go, and then put down what's become her standard-operating move -- a late kick which ended up placing her third overall 1:57.76. That just might get Whittaker into the final. 

Heat Three -- 

The third and final heat featured what may be the Olympic favorite at the distance: Keely Hodgkinson. 

The British star proved herself in cool fashion, leading the group through the first 400m in 57.5 before coming back under 60 seconds and finishing with a top time of 1:56.86 and advancement into the women's 800m final. 

South Africa's Prudence Sekgodiso was the only athlete to go with Hodgkinson as she pulled away over the final straightaway and she was second overall in 1:57.57. 

It seems possible that American Nia Akins, the U.S. champion at the distance, will also get in after a time of 1:58.20. 

SUMMARY -- 

The U.S. champion Nia Akins was handed a devastating final order. She was the second athlete out from the 800 final, alongside Great Britain's Jemma Reekie. Both were expected to reach the final. The American Juliette Whittaker, however, will feature in the concluding event, and it was her closing resolve that ultimately was the difference. 

The eight women through to the 800m final: Keely Hodgkinson (1:56.86), Tsige Duguma (1:57.47), Prudence Sekgodiso (1:57.57), Shafiqua Maloney (1:57.59), Juliette Whittaker (1:57.76), Renelle Lamote (1:57.78), Mary Moraa (1:57.86), Worknesh Mesele (1:58.06).

3:10 p.m. EST -- Men's 1,500m Semifinal

Heat One --

Jakob Ingebrigtsen's patience was on full display here. 

For the second straight heat, Ingebrigtsen's strategy allowed the field to move through the first 100 meters while the Norwegian slotted into the back of the pack. 

This time, however, he pushed early into the first lap to secure position and found Josh Kerr, moving to the front. He would not let it go. 

Ingebrigtsen cleared the way in heat one and crossed the line first in 3:32.38, followed by the British athlete Kerr in second in 3:32.46 and the American Cole Hocker in third in 3:32.54. The trio did just enough before letting off in the end and insuring their place in the final. 

Germany's Robert Farken was first out in seventh in 3:33.35.

Heat Two -- 

Yared Nuguse's preliminary round left much to be desired. His semifinal wasn't a stark change. 

The American was in full control from start to finish, winning the heat in 3:31.72 while his teammate, Hobbs Kessler, used smart tactics to claim his spot in second in 3:31.97, followed by Great Britain's Neil Gourley in third in 3:32.11. 

The biggest mover over the last 200 meters? That was Norway's Narve Gilje Nordäs, who had some work to do and eventually finished in the final qualifying position in 3:32.34, giving himself a spot in the final. Nordäs is coached by Jakob Ingebrigtsen's father, Gert. 

3:50 p.m. EST -- Men's 100 Meter Final

Holy smokes. 

Can we say that 10 times? 

In one of the craziest Olympic finals in history, Noah Lyles pulled it off. 

NOAH LYLES PULLED IT OFF. 

The American reacted the slowest out of the blocks -- tied with Letsile Tebogo at 0.178 -- but he had the fastest recorded speed over the 100 meter final, too, clocking just past 27 miles per hour. 

He finished in 9.79 seconds, needing the hundredth of a second to down Kishane Thompson, who led from the start and seemingly had it locked up. 

But the Jamaican tightened over the final 10 meters. 

Lyles took advantage, winning his second straight major championship after earning a World title last year at 100m. This race was, in fact, his hardest discipline, and now it may open the door for what could be a historic Olympic Games for him. 

Fred Kerley was also a smash success. The American bowed out of the semifinals last year at the World Championships. But he came ready to play in Paris. He finished third overall, winning bronze in 9.81 seconds. He won silver in 2021. 

Akani Simbine was fourth overall in 9.82. Oblique Seville, who was eighth, rounded out the field in 9.91 seconds.

When Are The Paris 2024 Olympic Games?

The Olympics begin on July 26 and end on August 11. The track and field events will began on Aug. 1.
