For my main sports, I follow Football and Ice Hockey pretty closely.
I watch tennis a bit when there’s a grand slam on, I follow badminton games on the BWF youtube channel sometimes. I watch the tour de france. I sometimes watch bandy, which is a sport similar to ice hockey. And I’m getting into cricket and baseball.
For football (soccer) I try to follow the Barcelona games and also some of the later stage knockout rounds from the champions league, tennis occasionally, when the olympics come around: gymnastics, rhythmic gymnastics, marathon, ice skating, table tennis can be fun to watch too.
