Nafissatou Thiam had to dig deep over the last lap of the women's pentathlon 800m to beat Poland's Adrianna Sułek and set a new world record as well as claiming her third European Indoor Championships gold medal at the Ataköy Arena in Istanbul. Here is all you need to know:

- Belgian Thiam came into the Championships with two European Indoor Championships golds and a silver as well as two Olympic golds, two World Championship golds and two European golds in the heptathlon.

- Thiam is still looking to beat American Jackie Joyner-Kersee's heptathlon world record, however there was a good chance of the pentathlon world record in Turkey based on her strength across all the events.

- On Friday morning, she opened up with 8.23s and 1077 points for a personal best in the 60m hurdles, then followed up with a season's best of 1.92m and 1132 points in topping the high jump standings.

- The last event of the morning session saw her top the field in the shot put too with a personal best of 15.54m and 897 points to lead Sułek by 144 points heading into the final two events later in the day.

- In Friday evening's long jump, Brussels native Thiam scored a season's best of 6.59m for 1036 points however Sułek jumped further to cut Thiam's lead by 10 points heading into the nail-biting 800m event finale.

- Sułek, the 2022 World Indoor Championship silver medallist, ran hard in the 800m and won with 2:07.17 to break the previous world pentathlon record only for Thiam to dig deep behind to finish in 2:13.60 which was enough to win gold and set a new world record mark of 5,055 points as compatriot Noor Vidts earned bronze behind Sułek.

- Thiam, 28, said: "It went so good. It was my first indoor competition of the season. Training has been going really well, but I didn't have the repetition especially in the jumps because I had a bit of a problem with my knee. To be able to do the world record and feel so good despite that is a great feeling because I know I can do so much better."
