Germany's Sideris Tasiadis is in danger of missing out on next year's Olympic Games in Tokyo after he failed to qualify for the semi-finals of the men's C1 at the Canoe Slalom World Championships in Spain.

Tasiadis, the London 2012 Olympic silver medallist, finished 16th in the second heat in La Seu d'Urgell.

It saw the German end comfortably outside the semi-final places, with the top 10 from each race progressing to the next round.

Britain’s David Florence, a three-time Olympic silver medalist, had no such trouble as he won the opening heat in 94.48sec.

Florence was 0.49 ahead of Slovakian Benjamin Savšek, who did enough for second place.

Ryan Westley, also of Britain, was third in heat one.

"To be totally honest, the really important thing for me was to make it through to the top 20, because I really need to just take it one step at a time,” Florence said.

"There’s a lot going on, it’s a massive week for all the guys in our team, and for so many teams who are looking to confirm their Olympic places and are fighting to get a good start for their Olympic selection."

Switzerland's Thomas Koechlin claimed victory in the second heat after clocking 95.68.

Miquel Trave of Spain was 0.29 behind in second, while Czech Republic's Lukas Rohan finished third.

France’s Marie-Zelia Lafont starred in the women's K1 as she clocked the fastest time of 99.83, 2.57 seconds ahead of Italy’s Stefanie Horn.

Lafont was the only athlete to go below the 100-second mark.

Britain’s Mallory Franklin was third fastest.

New Zealand’s Rio 2016 silver medalist Luuka Jones and two-time world champion Corinna Kuhnle of Austria also qualified but were made to work hard for their semi-final berths.

Action continues tomorrow.
