If the crazy weather during the heats session for the Olympic rowing is anything to go by, the athletes are in for some pretty challenging times ahead.
There were extremely high winds and choppy waves on the open water course - so much so that one boat capsized.
The Serbian men's pair Milos Vasic and Nenad Bedik succumbed to the conditions and were dunked in the Lagoa during their heat. And viewers were shocked that was even possible.
They also felt a bit worried for them about going under in that water.
Well, most people were sympathetic anyway.
Luckily for them though, the Executive Committee were obviously feeling nice and ruled the duo could continue in the next round of racing anyway.
Meanwhile Brits Katherine Grainger and Vicky Thornley didn't let the conditions affect them too much as they bagged their Olympic places in their heat - though Grainger said it was "probably the worst Olympic conditions I've ever raced in".
