Heats took place in three classes throughout the afternoon, the junior men’s double sculls, junior men’s single sculls and junior women’s single sculls.

The first race of the day, heat one of the junior men’s double sculls, was won by Italy in 6min 29.480sec ahead of Hungary in second and Lithuania in third.

The home favourites of Jakub Kynl and Jan Vacek then went in heat two and promptly won it in 6:31.720, to gain a spot in the quarter-finals.

The top four pairs in each heat secured a spot in the next round.

The others to make it through from the second heat were the Belgians Calvin Govaert and Jules Tuerlinckx, the Japanese Shunsuke Shimada and Yu Morinaga and the US pair Kristopher Fisher and Edward Tuckerman.

Heat three was then won by the Russians Aleksandr Suvorov and Maksim Zhevlachenko, before heat four was taken by Germany’s Paul Krueger.

The final heat, heat five, was lead from start to finish by Petros Gkiadazis and Grigorios Schizodimos from Greece.

In the men’s single sculls there were eight heats as the class features more entries than any other.

Only the top two from each race made it through and Peru had a strong start in the first heat.

Angel Sosa could not keep up his early pace however, and eventually finished third behind Germany’s Moritz Wolff and Belarus’ Ivan Brynza, who crossed the line in 7:04.850 and 7:07.050 respectively.

Heat two was won by Belgium’s Tristan Vandenbussche in 6:57.850 ahead of Australia’s Cormac Kennedy-Leverett, while heat three was taken by the reigning junior champion Clark Dean from the United States in 6:52.200, a world junior record.

Canada’s John Walkey took heat four in 7:14.020 and heat five was won by Switzerland’s Eric Von Bodungen in 7:11.290.

That race saw Uruguay’s Martin Gonzalez Volkman start the fastest, but his early pace was so quick, he completely ran out of steam before the end and finished four seconds behind the eventual winner.

Heat’s six, seven and eight were won by Moldova’s Ivan Corsunov, New Zealand’s Richard Hall James and Spain’s Koxme Burutaran respectively.

The final class of the day, the junior women’s single sculls, featured rowers from 29 different countries, including the 2017 junior champion Ester Briz Zamorano from Spain.

She led from the start in the final heat, winning it in 7:42.030.

Italy’s Greta Martinelli won the first heat in 7:49.180, while in the second heat the Greek rower Ermioni Lamprianidou hit a buoy and fell in the water.

That race was won by Argentina’s Maria Sol Ordas in 7:40.150.

Heat’s three and four were then taken by Germany’s Tabea Kuhnert in 7:59.220 and Romania’s Tabita Maftei in 7:48.760.

Tomorrow’s races are due to start with the semi-finals of the junior men’s single sculls.
