>>3956887>Indoor sportsIdk what country you're from, but most mainstream sports I can think of are outdoors.
Motorsports, cycling, tennis, football (American & soccer), baseball, cricket, track & field athletics, golf, skiing, bobsleigh, sailing, rugby, field hockey, skating, equestrian, rowing....
The major indoor sports that come to mind are really... basketball, badminton, volleyball, handball, gymnastics, swimming, diving, ice hockey, martial arts, skating (figure and speed), curling and uh.... table tennis...
Like, even when it comes to major sports, I can only think of NBA and NHL being indoors. F1, IndyCar, NASCAR, NFL, Premier League, Bundesliga, MLB, IPL, etc. all take place outdoors, or at the very least in massive floodlit stadia that are about as bright as regular daylight conditions.
