Day 7 of Olympic track and field action got underway at the Stade de France on Thursday morning, featuring the opening of the women's heptathlon, men's and women's 4x100m heats, women's shot put qualification, and repechage rounds in the women's 100mH and men's 800m.

Yesterday's evening session featured finals in the men's 400m, 3000m steeplechase, and discus plus women's pole vault finals. Several more final and semifinal fields will be set in the qualifying rounds this session.

This morning, five qualifying events will be contested, consisting of repechage "second chance" rounds in the women's 100mH and men's 800m, as well as the first rounds of the women's shot put and both 4x100m relays. Alongside those events, the two-day women's heptathlon will begin featuring American Anna Hall.

6:00 AM EDT: Men's 800m Repechage Round

Only the winner of each of 4 heats will auto-qualify for the semis, plus the next two fastest losers.

Heat 1

After a 53.1 opening split, Botswana's 1:43 man Kethoboglie Hainhura holds on to win the first heat in 1:45.52. (Back in 6th, Dennick Luke sets a new national record for Dominica in 1:46.81.)

Heat 2

The biggest name in the 2nd heat is Koitakoi Tidali, who surprised with a 1:42 clocking to make the Kenyan team. After 52.2 at the bell, Penn State's Handal Roban briefly challenges the lead but falls back and Jesus Tonatiu Lopez of Mexico takes it to win, 1:45.13. Kidali sits 6th in 1:46.37.

Heat 3

1:43 Frenchman Benjamin Robert will have his last chance at qualification, and after a 51.8 first lap Robert takes the lead with 100m to go but is ultimately passed by Italy's Simone Barontini in 1:45.56. Robert's time won't be quick enough to advance based on the first two heats.

Heat 4

The only American not to advance from the first round, Brandon Miller, leads 400 at 50.2. He gets it done with the fastest split of the day in 1:44.21, a nice display of frontrunning. Behind him Mohamed Ali Gouaned of Algeria and Tobias Gronstad of Norway both PB in 1:44.37 and 1:44.57 to notch both time qualifiers.

5:35 AM EDT: Men's 4x100m Quarter-Finals

The men's team will be Christian Coleman, Fred Kerley, Kyree King, and Courtney Lindsey. Look out for the British squad of Jeremiah Azu, Louie Hinchliffe, Richard Kilty, and Nethaneel Mitchell-Blake as well. The South African team of Bayana Walaza, NCAA star Shaun Maswanganyi, Bradley Nkoana, and 100m finalist Akani Simbine should also contend. Marcell Jacobs will run 2nd leg for the Italian team.

Like with the women's heats, top 3 plus next 2 fastest advance.

Heat 1

It'll be Nigeria, the Netherlands, South Africa, Great Britain, United States, Japan, Italy, Australia in lanes 2 through 9 for this heat. With the history of American 4x1 blunders at the Olympics, all eyes will be on the red, white and blue exchanges.

It's clean all throughout! There's little to criticize here from Team USA, with Lindsey (8.88 split) anchoring all alone to post a dominant win, 37.47. South Africa posts the fastest anchor split of 8.86s to come in 2nd, 37.94. Great Brtain gets the final auto-Q in 38.04.

Abdul Hakim Sani-Brown of Japan actually had the fastest first split of 10.32, ahead of even Christian Coleamn's 10.40. On the second leg, NCAA champ Hinchliffe's 8.88 bested Kerley's 8.98, as Kerley appeared to be playing it safe for the pass. Nigeria's Alaba Akintola surprised for the fastest 3rd leg in 9.20.

Heat 2

It's Liberia, Brazil, Ghana, China, Canada, France, Jamaica, and Germany. Jamaica's team is Ackeem Blake, Jelani Walker, Jehlani Gordon, and Kishane Thompson. Tokyo 200m gold medalist Andre De Grasse is anchoring Canada's team, and NCAA champ Joseph Fahnbulleh will anchor Liberia.

Jamaica has a good start but major issues on the 2nd exchange, and Canada flubs the third exchange. It's chaos out there as China ends up winning the heat. Thompson tries desperately to make top 3 but he doesn't do it -- and their time of 38.45 isn't fast enough to get in! We'll have a Jamaica-less men's 4x100m final.

Final results: China 38.24, France 38.34, Canada 38.39. The time qualifiers will all come from the first heat, which means that Italy will be back to defend their men's 4x100m title in the finals.

Looking at the World Athletics splits, here are the fastest splits per leg in this heat:

• Leadoff: 10.48, Canada's Aaron Brown
• 2nd leg: 9.01, Jamaica's Jelani Walker
• 3rd leg: 9.21, Ghana's Ibrahim Fuseini
• Anchor: 9.13, France's Pablo Mateo

5:10 AM EDT: Women's 4x100m Quarter-Finals

Top 3 in each heat plus the next 2 fastest will advance.

The American women's team is announced as Melissa Jefferson, TeeTee Terry, Gabby Thomas, and Sha'carri Richardson. The Jamaican team of Alana Reid, Kemba Nelson, Shashalee Forbes, and Tia Clayton is missing some of their heavy hitters like Shericka Jackson and Shelly-Ann Fraser Pryce, who withdrew from their individual events. Some thought they might be tapped for the relays anyways, but that didn't play out. Marie Josee-Talou Smith will appear here anchoring the Cote D'Ivoire team despite pulling out of the 200m, though.

Heat 1

Team USA is lined up to face Switzerland, Belgium, Italy, Australia, Germany, and Poland, and Cote d'Iovoire.

And they get it done! That second exchange from Terry to Gabby Thomas was a little rough, but Sha'Carri still gets it in striking distance and passes Germany to win the heat in 41.94. Switzerland nabs the third auto-spot with Cote d'Ivoire on the outside looking in, waiting to see if their 42.64 time qualifies.

According to the World Athletics timing, Richardson posts the fastests split of the heat with 9.99 on the anchor with a running start. Terry's 10.02 2nd leg was the second fastest overall split. Jefferson with 11.34 had the fastest leadoff. It was Gabby Thomas with 10.59 on 3rd leg that lacked the most -- the fastest 3rd leg was Gina Luckenkemper of Germany with 10.12s.

Heat 2

It's Trinidad and Tobago, Spain, Nigeria, the Netherlands, France, Great Britain, and Canada in this heat. The British team is missing both Daryll Neita and Dina Asher-Smith. The Nigerian team featuring Favour Ofili and Tima Godbless will be one to look out for, along with of course the Jamaicans.

It's surprisingly Great Britain leading France taking 1-2, 42.03 and 42.13. Jamaica wasn't even in the picture until the very end, with anchor Tia Clayton making up ground to get that final auto-qualifying spot. Team Canada runs a national record of 42.50 to make it in on time in 4th.

The Netherlands behind them in 42.64 takes the final time qualifier. We're now hearing that Cote D'Ivoire (TR24.7) and Belgium (TR17.2.3) are borth disqualified from the first heat.

According to World Athletics splits, Amy Hunt's third leg for Team GB was the fastest of the field. They also had the fastest first leg in Bianca Williams (11.37), while Nigeria had the fastest 2nd leg in Favour Ofili (10.09). Canada's Audrey Leduc actually had the fastest anchor in the field to secure their team's national record and final berth.

5:05 AM EDT: Women's Heptathlon High Jump

The opening height is 1.56m, but most are passing the early heights to reduce the amount of work required. We can expect

Along with most of the field, American Chari Hawkins passes 1.56, 1.59, 1.62, 1.65, and 1.68 to attempt 1.71m -- but she misses three times, and there's no going back now. With a no-height, she'll score 0 points in this event, and she's seen saying "I don't know what to do" speaking with her coach. She can continue, but this will end her medal hopes.

While Hawkins makes her decision, the bar gets higher and higher. Anna Hall and Taliyah Brooks have both cleared 1.77m, but they both miss first attempts at 1.80. High jump superstar Nafi Thiam waits until 1.80 to debut and she makes it. Brooks is the second American out, failing all attempts at 1.80m while Anna Hall makes it on her 2nd attempt.

So far, Noor Vidts of Belgium leads the heptathlon standings, with KJT second and Americans Taliyah Brooks and Anna Hall in 3rd and 4th.

With just Hall, Thiam, and KJT still in the competition, the other track events have ended meaning the packed stadium is still here just to cheer on the heptathletes. All clear 1.89m, and Thiam clears 1.92 on her first attempt while KJT clears on her third. Anna Hall doesn't make 1.92 so will have to settle for 1.89, while both Thiam and KJT fail to make 1.95.

With the high jump all finished, standings show KJT now leading with 2197 points, ahead of Nafi Thiam (2173) and Anna Hall in 3rd (2164).

4:35 AM EDT: Women's 100m Hurdles Repechage Round

Top two per heat will qualify for semis. It's the second chance for viral star Michelle Jenneke in the first heat, but it's Marione Fourie of South Africa and Maakya Tjin-A-Lim of the Netherlands that take top two, 12.79 winning time. It was a photo finish for the last spot that left Viktoria Forster out.

It's another photo finish in the 2nd heat, but Ebony Morrison (12.82) and Maribel Vanessa Caicedo (12.828) come out on top over Reetta Hurske (12.830). That's a close one for the final spot.

In the third heat, Finland's Lotta Harala (12.86) and Japan's Yumi Tanaka (12.89) will round out your semifinal qualifiers.

4:25 AM EDT: Women's Shot Put Semifinals

Two groups are throwing simultaneously, and the Americans sit towards the end of the throwing orders. All those who throw 19.15m or top 12 will make it through.

2020 Olympic medalist Raevyn Saunders slips their left foot and will foul their first attempt, and Jaida Ross throws 18.58m. So far, it's only Sarah Mitton (19.77m) and Maddison-Lee Wesche (19.25m) to hit the auto-Q.  

On her final throw, American U of O thrower Jaida Ross looks like she hits the auto-Q, but it's a foot foul. World Indoors medalist Yemisi Ogunleye throws 19.24 on her third attempt to get in automatically alongside Mitton and Wesche.

Chase Jackson has two fouls for her first two throws. On her last chance, it's legal but it is outside the top 12 -- 17.60m. Jackson's Olympics are officially over, and she knows it as she's crying walking out the ring. A huge blow for the US throwing squad not having the American record holder in the finals.

Saunders needs about 18.12m to make it in now on their 3rd throw. And it's good enough! 18.62m is outside the auto-Q, but she will make the top 12 and be in the final alongside Ross.

4:05 AM EDT: Women's Heptathlon 100m Hurdles

Heat 1

Adrianna Sulek-Schubert of Poland takes the first heat in 13.32, but it's 2x World Champion Katerina Johnson-Thompson's 13.40 for 2nd that really exceeded expectations here. 

Heat 2

This isn't what you want to see at all -- Germany's Sophie Weibenberg pulls up injured after hitting a hurdle in warmups. Pulled off in a wheelchair, her heptathlon is over before it begins.

Dutch athlete Emma Oosterwegel takes the heat in 13.41, but we're keeping an eye on Anouk Vetter and Nafi Thiam at 13.46 and 13.49 respectively. Not their best events, but it will be enough to stay in contenton.

Heat 3

All three Americans adorn this heat, which is one of Anna Hall's strengths. Hall clips hurdle 6 and loses some time at the finish. It's Turkey's Annik Kalin 12.87 for the win, behind her Taliyah Brooks 13.00, Chari Hawkins 5th 13.16, and Hall 6th 13.36. Not a great start for Hall, but she's still ahead of KJT and Thiam.
