Naomi Riches will row for Paralympic gold on Sunday morning after Great Britain's mixed coxed four comfortably qualified for the final at Eton Dorney.

Competing in the LTAMix4+, the Harrow rower's boat won the second of this morning's heats in 3 minutes 23.59 seconds, more than five seconds quicker than second-placed USA.

However, the British team are likely to have their work cut out to beat the Germans, who won the first heat in a new world best time of 3.15.91.

Sunday's final is scheduled to start at 10.30am.

“I’m pleased with the race, we had a job to do and we executed it," said Riches, a five-times world champion and the only survivor from the Beijing Four which won bronze.

"The conditions were tricky but we train at Caversham [not far from the Paralympic venue] so we are fairly used to them and just tried to relax. The crowd were amazing but we have to stay in our bubble and listen to Lily [cox Lily van den Broecke].”
