Biles hits the heights early on in Rio


There are certain to be at least a few mismatches during this month's Olympic Games, when the heavyweights take on the underdogs across 42 different sports in Brazil.

Simone Biles offered a visual representation of that concept on Tuesday, albeit not in the form of a direct sporting contest.

The artistic gymnast, expected to be among the stars of the Games, ran into a fellow athlete from Team USA upon her arrival in Rio.

And the 1.45 metre 19-year-old could not resist posing for a picture with towering 2.03m volleyball player David Lee.

Biles and her team-mates also located the iconic Olympic rings in the athletes' village as they prepare for the women's gymnastics competition to get under way on Sunday.
