CANOE - SLALOM:A relived Jessica Fox is through to the semi-finals of the K1 canoe slalom event at the Whiteweater Stadium at Deodoro.

Fox, the silver medallist from London, qualified with the second fastest time behind Italian Stefanie Horn.

After her first run, the 22-year-old was in eighth position and was a little anxious before her second run.

“During the break between runs we analysed the video. We watched my race as well as some of the replays of the girls who did the moves down the bottom really well,” she said.

In fact, Fox was aware she was going well in her second run and coasted a little in the final stages.

“Definitely very relieved,” she said after qualifying.

“I thought I had qualified without needing the second run but I really wasn’t sure.

“My second run was so much better. From the start I felt free, and the run flowed really well.

“I was more alert and more focused. I felt I was in control. My goal today was to be somewhere in the top eight really so I’m really happy with second."

After breaking through with her performance in London at age 18, Fox is full of confidence heading into Thursday’s final day.

“In London I was fourth after the heats and here I’m second that’s an improvement," she said.

The top 10 in the semi-final advance to the final, also on Thursday.
