Follow along with us for the final day of the 2017 IAAF World Championships in London. The first race starts at 1:35pm CT.

Women's 5000m Final

We've got Shelby Houlihan, Molly Huddle, and Shannon Rowbury on the line for Team USA. Huddle ran the 10,000m and finished 8th last Saturday. 

Around the first turn, Rowbury got folded into the middle of the pack while Huddle and Houlihan went to the back to stay out of the commotion. They're tightly bunched and moving along at a pedestrian pace. This is looking very tactical so far--82 seconds for the first lap.

The pack has begun to spread out a bit. Almaz Ayana and Senbere Tefiri of Ethiopia are trading off leading the group. 

3:55 at 1200m. The pace is picking up as the front 10 string out behind Ayana and Helen Obiri. 

5:01 at 1600m. Ayana and Obiri have gapped the field and are about 20 meters ahead of the next-closest group of five runners. Team USA is far behind. 

6:07 at 2000m. The gap has extended slightly, and Obiri is right on Ayana's heels.

65, 66, 68.5 seconds for Ayana and Obiri's last three laps. They now have a 50-meter lead on the next-closest group. 

8:23 for 2800m. No one has made an attempt to try and make up the lost ground on the front-runners.

8:58 for 3000m. It looks like it will be Ayana and Obiri all the way as they continue to push the pace without any response from the rest of the field. 

11:39 through 4000m. Rowbury is gradually moving up and picking off runners, but still has a ton of ground to make up in order to get a peek at grabbing bronze.

Obiri tried to make a move on the outside of Ayana, but the Ethiopian responded with a quick burst of speed, and she reconsidered. Obiri is still tucked behind Ayana.

OBIRI IS PULLING AWAY FROM AYANA! She's erupted around the turn with 200 meters to go! It's ALL OBIRI!!!!!!!

OBIRI is your world champion with a 61-second closing lap! Ayana didn't seem to have any gas left in the tank when Obiri made that massive move on the backstretch.

Sifan Hassan of the Netherlands won the sprint for bronze with a time of 14:42.

Rowbury was the top American finisher in ninth in 14:59, then Huddle in 12th (15:05), then Houlihan in 13th (15:06). 

Women's 800m Final

Team USA is represented in this final by Ajee Wilson and Charlene Lipsey. Wilson has looked cool, calm and calculated through the rounds, and ran her PR of 1:55.61, the new American record, against Caster Semenya of South Africa at the Monaco Diamond League last month.



And they are out QUICKLY in 27.08 for first 200m. Francine Niyonsaba, Wilson and Semenya at the front of the pack as they continue to charge down the backstretch.

WOOF! They sprinted through the halfway mark at 57.98, and aren't relenting. 

Booking it through 600m at 1:27.07, and Wilson is making a push to lead. Niyonsaba quickly reasserted herself and is marching through the final turn. 

BUT HERE COMES SEMENYA. Niyonsaba and Wilson are going to make her work for it; they're running shoulder-to-shoulder approaching the homestretch. 

Swinging wide around Niyonsaba and Wilson, Semenya storms down the final 100m to finish in 1:55.17--a new PR for her and the fastest time in the world this year!

Niyonsaba held on for silver in 1:55.92, and Wilson has earned bronze in 1:56.65 for the United States!

Men's 1500m Final

In his first time competing on the global stage, Johnny Gregorek became the only American to qualify for the men's 1500m final after reigning 2016 Olympic gold medalist Matt Centrowitz and Robby Andrews both couldn't make it past the semifinal. Can Gregorek keep the magic alive for a shot at the podium? 

He'll have to get past a stout field containing the likes of Timothy Cheruiyot, Nick Willis, Asbel Kiprop, Elijah Manangoi and Filip Ingebrigsten. 



Gregorek is staying out of traffic toward the back.  

1:01.59 through the first 400m as Cheruiyot has assumed the lead. The Kenyans--Cheruiyot, Manangoi, and Kiprop--are 1-2-3 through 800m (1:57.65).

Through 1200m, it's still the Kenyan front-runners--Cheruiyot (2:53.68), Manangoi (2:53.87), Kiprop (2:53.98)--but with Ingebrigsten in hot pursuit in fourth (2:54.03).

Ingebrigsten has charged forward to challenge the attempt at a Kenyan sweep! Kiprop has fallen off the pace and is out of the top five!

Manangoi has WON the world title in 3:33.61, followed by Cheruiyot in 3:33.99, and bronze belongs to Ingebrigsten (3:34.53), who ran fearlessly to edge out Adal Mechaal of Spain at the line. Kiprop ultimately finished ninth (3:37.24).

Gregorek finished 10th (3:37.56). 

Women's 4x400m Relay Final

The United States enters this final with the 2017 world champion over 400m, Phyllis Francis (anchor leg), and the 2017 bronze medalist, Allyson Felix (second leg). Quanera Hayes (first leg) and Shakima Wimbley (third leg) will round out the rest of the team. Felix ran the fastest time in the world this year, 49.65, in London in July, while Hayes ran the second-fastest time, 49.72, in June. Hayes is singing and looking very comfortable prior to the race.



A great exchange between Hayes and Felix, who is rapidly gapping the field in a MAJOR way! Hayes' unofficial split is 50.98.

Jamaica is OUT--Anneisha McLaughlin-Whilby ended up on the ground 50 meters after receiving the baton! She looks injured, and was loaded onto a wheelchair by medical staff. 

It's all Felix as she bolts comfortably down the homestretch a solid 15 meters ahead of the next-closest competitor. Her unofficial split: 48.2!!!!

Wimbley extended the lead and handed it off to the reigning world champion, Francis. She cruises across the finish line in 3:19.02, the fastest time in the world this year, to claim gold for Team USA. That makes the total 16 world-championship medals for Felix.

Holy bonkers:

Great Britain held off Poland in a crazy dash for the line between anchor legs Emily Diamond (GBR) and Justyna Swiety (POL), who crossed the line in 3:25 and 3:25.41, respectively. 

Men's 4x400m Relay Final

Now, it's time for the men! Let's see if the American men can replicate the women's gold here. Team USA's young crew contains three collegiate sprinters: Wil London (first leg), Michael Cherry (third leg), and Fred Kerley (anchor leg), whose 43.70 this season reset the NCAA record over 400m. Gil Roberts, who has helped the U.S. reach the podium on the world stage before in the relay, will take it out on the third leg.

This will be a much closer race--look for Trinidad & Tobago and Great Britain to challenge the Americans.



Around the first 200m, all runners are very even. Belgium is pulling away down the homestretch, but London kicked hard in the final 20 meters, and Team USA is now solidly in first.

Jereem Richards, who earned bronze in the 200m, is challenging Roberts down the homestretch! He faded a little, but it helped Trinidad & Tobago make their way into second.

Great Britain's Rabah Yousif is in third on the third leg, and Team USA's Cherry is leading the group by five meters ahead of Trinidad & Tobago's Machel Cedenio. 

The U.S. and Trinidad & Tobago are DEAD EVEN at the final handoff!!! Can Kerley find the energy to hold off T&T's Lalonde Gordon?!?!

WOW. WOW. WOW. Trinidad & Tobago are first-time world champions in the 4x400m relay as their anchor leg takes down Kerley!!!!
