The names of the thirty semifinalists are already known

Second qualification run in C1M category came right for Stanislav Ježek (CZE) since he had precisely the same time as Alexander Slavkovsky (SVK) in the first runs - 88.38. This time, Slavkovský got two time penalties. Australian Kynan Maley improved a lot. Due to the fact that only the better one of the two runs counts, he got the third place in heats thanks to time 91.26. 
Altogether, there's going to be 30 single canoeists in semifinals, 3 of them are Czech. Alongside Ježek,  there are Tomáš Indruch (4th place with a time 91.93) and Vítězslav Gebas (11th place so far with time 93.75).
