Mike Dawson ended a frustrating canoe slalom world championship campaign with something of a silver lining, finishing runner-up in the overall World Cup extreme slalom series.

The two-time Olympian was eliminated early on the final day of competition in Brazil, missing out on the extreme slalom quarterfinals after a contentious disqualification call.

But he'd still done enough to finish behind Russian Pavel Eigel in the overall standings, despite some late jitters.

'My disqualification was pretty tough to swallow and I was stressing near the end because it looked like I might not even make the podium overall but luckily the other contenders all dropped out too,” Dawson, who was 34th in the men's K1 yesterday, says.

Italian Christian De Dionigi claimed the world championship extreme title, ahead of Boris Neveu (France) and Argentina's Thomas Bersinger.

Eigel was knocked out in the quarterfinals, just hours after winning Russia's first-ever world championship medal when he finished third in the men's K1 final, behind Germany's Hannes Aigner and Czech Jiri Prskavec.

The records continued to tumble for Australia's Jessica Fox, meanwhile, with her victory in the women's C1 confirming her status as the greatest female paddler in the history of the sport.

She has now won the C1 title four times, won the K1/C1 double for a second time and managed to paddle through an entire season undefeated in C1.

Her win takes her total world titles across all disciplines, including teams, to nine, leapfrogging her mother, Myriam Jersusalmi, to become the most successful female canoe slalom paddler of all time.

A day earlier, she overtook her father, Richard, as the most successful individual athlete of all time.

'It's been the perfect season, the perfect world championships, I'm absolutely thrilled,” Fox says.

'Yesterday was really hard because I couldn't appreciate what I had achieved because I had the C1 semis in the afternoon. But now all the emotion is there, it's amazing to share it with everyone that's here – my team, my family – I can't wait to get home and celebrate.

Kiwi Luuka Jones finished seventh in the K1 final and 12th in the C1 after just missing the top-10.

The 2019 canoe slalom world championships, which doubles as a Tokyo 2020 qualifier, will be held in La Seu, Spain.
