Men's cycling road race definitely - i love this route, it is very interesting, it should be a great race, at least as good as in Rio, but more safe for the riders, I hope.
I remember Alaphilippe and Evenepoel had their supporters here, but I'd rather still bet on Roglic.
Van Avermaet won virtual Tour of Flanders the other day - I'm not sure if it means much, but he should be in a great form in Tokyo. Great enough for second gold? Not sure. But who knows, cycling road race is always unpredictable.
From Polish perspective - I was waiting for men's volleyball. Poland vs Iran - there is a long history of tense matches between these two teams. So it should be another good match, five sets I guess. And after that - USA vs France - so a good piece of volleyball in the afternoon european time.
Swimming and artistic gymnastics qualifications - I always watch these two disciplines carefully. No medals yet, but already looking for some surprises.
In tennis - maybe Hubert Hurkacz could have an interesting match.
I'm not really into archery - but basketball 3x3 could be something new to watch. Poland had bronze in 2019 world cup, but it is very tough challenge for them to qualify for the olympics. I'm not sure they are to able to do that.
Anyway, I would have to wake up at 2 am maybe, but what the hell - it's olympics time! ;-) it would be fun.
