Hungary earned four gold medals across the under-23 and junior competitions at the International Canoe Federation (ICF) Marathon World Championships in the Chinese city of Shaoxing.
Lili Katona dominated in the women's under-23 K1 race, achieving Hungary's first gold of the day.
She finished in 1hr 49min 53.66sec, beating second-placed Anna Sletsjoee of Norway in 1:51:15.13 by over a minute.
Osa Irata of Spain was third in 1:51:30.55.
Katona's victory came despite a three-month absence from training with an injured shoulder.
"It was my dream to be a world champion, and now my dream is true, it's amazing," she said.
"It was hard because I had a problem with my shoulder, so I didn't know if I could do it.
"It was a surprise for me."
Zsombor Ory and Tamas Erdelyi got Hungary's second gold after outsprinting David Evans and Hamish Mackenzie of South Africa in the men's junior K2, crossing the line in 1:32:29.11.
Evans and Mackenzie settled for silver in 1:32:30.97, while Nikolai Thomsen and Philip Knudsen of Denmark were the bronze medallists in 1:32:38.22.
Benedek Horvath followed up his gold medal from the men's junior C1 with another gold in the men’s junior C2 alongside Oliver Nagy.
The Hungarian duo were victorious in 1:26:50.28, getting past Zihang Wang and Jiadong Zhu of China in 1:27:16.69.

He triumphed in the under-23 race in 1:5 49.56sec, beating fellow Dane Thorbjorn Rask in 01:52:26.46.
"I'm super happy to be able to do what I’m good at, and to be successful is just amazing," Pedersen said.
