The three-day Grand Prix finished with the heavyweights rounding off a fascinating competition in Croatia's capital.

Russia were the runaway overall leaders as they finished with a dominant medal haul of three golds, three silver and five bronzes in total ahead of Poland and France, who also impressed on all three days.

In the first men's action of the day, the under 90 kilogram competition, Russia's Alexander Grigorev clinched his second Grand Prix gold medal by defeating the top seed Li Kochman of Israel.

Grigorev was unstoppable and wrapped up the gold medal with a thunderous osoto-gari, earning an ippon when already in front by a yuko. 

The first bronze medal was awarded to Poland's Piotr Kuczera after he beat German Dario Kurbjeweit Garcia inside three minutes and the other went to Great Britain's Max Stewart, who defeated Gabor Ver of Hungary.

In the second male event today, Russia's Adlan Bisultanov defeated Michael Korrel from The Netherlands in the under 100kg category.     

Austrian Laurin Boehler won the bronze medal as Hungary's Zalan Ohat could not compete having injured his shoulder while winning the previous round. 

The second bronze medal was won by Sweden's Joakim Dvarby, who beat Moscow Grand Slam bronze medallist Milan Randl of Slovakia.

The third and final gold medal in men's competitions today, the over 100kg tournament, was won by World Judo Masters winner Daniel Natea of Romania.

He won his first Grand Prix event with an ippon in the last contest of the day as he beat German Sven Heinle.

The two bronze medals were claimed by Stanislav Bondarenko of Ukraine and Belarus' Benjamin Harmegnies, as they overcame Slovenian Vito Dragic and Frenchman Hamza Ouchani respectively.

The first gold medal on another busy day in the women's competitions was won by Abigel Joo of Hungary in the under 78kg event.

Joo outworked Guusje Steenhuis of The Netherlands in the gold medal contest and scored a yuko from a ko-uchi-gake with 40 seconds left, the only score of the four minute contest.

France's Sama Hawa Camara won the first bronze medal as she beat another Dutch competitor, Karen Stevenson.

Russia's Antonina Shmeleva defeated home favourite Brigita Matić  for the second bronze medal to the disappointment of the home crowd.

In the over 78kg final, Bosnia and Herzegovina's Laris Cerić beat German Carolin Weiss to claim the gold medal. 

Rio 2016 Olympian Ceric scored a yuko from an osoto-makikomi and Weiss could not reply with an attack of any substance.

The first bronze medal was won by Lithuanian Sandra Jablonskyte, who was too strong for 18-year-old European Youth Olympics Festival bronze medallist Mercedesz Szigetvari of Hungary.

Ivana Šutalo of Croatia defeated Serbian Milica Zabic to win the second bronze in front of her home crowd.
