Event #7 - 800m
Nafi Thiam has joined legendary company.
Despite finishing 13th in the 800m at 2:15.93, the Belgian became the second woman ever to repeat as Olympic champion in the heptathlon, joining American track & field icon Jackie Joyner-Kersee.
Her final total of 6791 is just 19 points off her winning score from Rio.
The Netherlands picked up both other medals, as Anouk Vetter and Emma Oosterwegel took home silver and bronze, respectively.
Event #6 - Javelin Throw
Nafi Thiam won her second consecutive event to regain the overall heptathlon lead over Anouk Vetter.
Thiam's second of three throws was best in the entire field at 54.68m (179 ft, 4.8 in), worth 951 points.
Vetter's mark of 51.20m was fourth-best, but a full 68 points behind Thiam.
American Kendell Williams logged the seventh-best throw to lift her into a one-point lead in the bronze medal position. She'll have to beat out Emma Oosterwegel in the 800m to hang onto it, though.

Event #5 - Long Jump
Belgium's Nafi Thiam, the defending Olympic gold medalist, began her charge back towards overall lead with a top mark in the long jump at 6.60m (21 ft, 7.8 in).
However, Dutch heptathlete Anouk Vetter was only 13 centimeters behind, keeping the lead but by the slimmest of margins.
The two athletes are separated by four points.
Behind them, Thiam's teammate Noor Vidts remains in bronze medal position with two Americans — Annie Kunz and Kendell Williams — close behind. Williams and Kunz managed the second- and fifth-best jumps of the event, respectively.

Event #4 - 200m
The heptathlon gold medal will not return to Great Britain in 2021 as Katarina Thompson-Johnson suffered a re-injury to her right leg during the first heat of the 200m event.
In a moment of spirit and toughness, she refused help off the track and instead finished the race, though withdrew from the competition shortly thereafter.
It wasn't the only shakeup to the top five. Belgium's Nafissatou Thiam, who had led after the prior two events, was knocked down to the third overall spot after a disappointing 18th-place finish in the 200m at 24.90.
Anouk Vetter of the Netherlands finished third in 23.81 and emerged as the new overall leader of the competition.

Event #3 - Shot Put
American Annie Kunz vaulted herself into the top five with a strong throw of 15.15m in the shot put, good enough for the third-best mark at 871 points.
The leader, Belgium's Nafissatou Thiam, managed 14.82m on her first throw for the fourth-best result, more than enough to keep her lead.
The other Americans, Erica Bougard and Kendall Williams, struggled in this event, finishing 19th and 22nd, respectively. Both fell out of the top five overall.
Katarina Johnson-Thompson only managed 15th-best in the event.

Event #2 - High Jump
Defending Olympic gold medalist Nafissatou Thiam surged into the heptathlon lead with an unmatched high jump mark of 1.92m (6 ft, 3.6 in), good enough 78 points more than any other athlete in the event.
She did not even attempt a jump until 1.80m, after several of the 23 competitors had already been eliminated. Her only misses came when trying to elevate the mark to 1.95m.
American Erica Bougard and Great Britain's defending world champion Katarina Johnson-Thompson both notched the next-best result at 1.86m (6 ft, 1.2 in).
The leader after the 100m hurdles, American Kendell Williams, finished in an eight-way tie for eighth place in the high jump with a mark of 1.80m, dropping her to the fifth position overall.
TOP 5 AFTER HIGH JUMP (2/7)

Katarina Johnson-Thompson (GBR) - 2138
Noor Vidts (BEL) - 2115

Event #1 - 100m Hurdles
American Kendell Williams went out to an early lead in the event with the top time in the 100m hurdles of 12.97 out of Heat 3, which produced the four fastest times overall.
The opening event is one of Williams' strongest, and also one of the weakest for defending Olympic gold medalist Nafissatou Thiam of Belgium, who relies primarily on her jumping and throwing ability to post big scores.
Thiam finished with the 15th-best time in the event at 13.54. Great Britain's defending world champion, Katarina Johnson-Thompson, secured a solid seventh place start in 13.27.
