Ireland's women's four team of Emily Hegarty, Eimear Lambe, Aifric Keogh and Fiona Murtagh recorded an effortless win in their heat at the final Olympic qualification regatta in Lucerne this morning.

More than 400 rowers from 49 countries are chasing Tokyo 2020 berths in the 14 Olympic classes at the scenic Swiss event.

Ireland led from start to finish in calm conditions over the 2000m course on the 'Lake of the Gods', with Russia, Ukraine and Germany all trailing in their wake and heading for the repechage.

The final takes place on Sunday morning. It had been due to take place on Monday but due to forecasted poor weather, World Rowing have brought the race forward.

Elsewhere Daire Lynch booked his place in the A/B single scull semi-final which also takes place on Sunday morning.

Having finished third in his heat, Walsh went on to win his repechage in a time of 06:59.99, beating the crews from Spain, Cuba and Moldova. He'll need a top-three finish to qualify for the final where two Olympic qualifying spots are up for grabs.

The lightweight women’s double of Aoife Casey and Margaret Cremen also won their heat with a time of 07:09:29 to make Sunday's A/B semi-final. The top three crews will enter the final and subsequently battle for three Tokyo Games qualifying places.
