I watch everything. once in four years there is such an event. I cannot separate one sport. at the Olympiad in all forms all in a new way !!! so everything is interesting!
My favorite sport would be the winter Olympics and that would be ice hockey and speed skating. I don't watch the summer Olympics they don't interest me at all. But I would like to see the Olympics banned the pros.
For Winter I definitely have to go with snowboarding and Shaun White is obviously a huge reason. For the summer I would choose basketball because I enjoy the USA spanking every other team and making them look like children to the US team's superhumans.
What's the Olympics without the marathon? Excellent summer Olympic sport - running in different variations. Short distance, hurdles, relay, middle distance and marathon. Excellent winter Olympic sport - skiing. In all varieties. Ski jumping, freestyle, slalom, cross country skiing, biathlon.
