Australia's Ken Wallace finished the Canoe Sprint World Championships in Duisburg, Germany on a high on Sunday, adding gold in the K1 5000m to his silver in the K1 1000m.

On Saturday Wallace finished a hard-fought second over 1000m, but he went one better 24 hours later when he won his first World Championship crown since 2010.

Wallace controlled the race from start to finish, finishing more than two seconds clear of Argentina's Daniel Dal Bo.

Unfortunately the gruelling race took its toll on Wallace, who was unable to recapture the spark and finished at the back of the pack in the K1 500 field later in the day.

Despite the impressive result, Wallace said the 5000m event was not exactly his favourite.

"A lot of people would think so but no I hate it," he said.

"I was more nervous then, than what I was before the 1000 metre final just because things can go pear shaped so fast, you can be in the lead and then have someone crash straight into you."

Meanwhile, Australia's Olympic K4 gold medallists Tate Smith, David Smith, Murray Stewart and Jacob Clear claimed bronze.
