Canoeing
Ken Wallace and Olympic debutante Lachlan Tame have taken home the bronze in the men’s K2 1000m behind strong crews from Germany and Serbia.
Speaking ahead of the race yesterday, canoeing team leader Richard Fox had indicated both teams would give Australia a run for its money, and he proved correct.
"We held next to [Germany] at the 500 metres and we knew they were going to push at the third 250 metres, but just to be next to them, going to head-to-head with them was fantastic, they simply raced better than us today, in a tough race we are just stoked to be on that podium," Wallace told olympics.com.au.
In the lead up to the race Wallace had traced the outlines of his three-year-old and nine-month-old sons' hands on his paddle and they were clearly visible during the race.
In final b of the men’s K2 200m, Daniel Bowker and Jordan Wood finished in third position.

At this point she is sitting just 48 points off the leader, Poland's Oktawia Nowacka.
"Last Olympics the fencing part was the worst for me so I really tried hard these last four years trying to change my fencing style and work really hard on it," she said.
"It’s just paid off. If I got 50 per cent [wins] I was going to be happy and I got over 50 per cent so I’m just over the moon."
Tomorrow the fencing round will conclude and athletes will also compete in swimming, show jumping, and combined running and shooting.
Eposito's brother Max is also competing in the modern pentathlon and is currently participating in the men's fencing ranking round.
