I read from discriminate to discuss.

I don't understand the discriminator.

The weight of the discus depends on the age and sex/gender (that's a whole other conversation) but they range from 0.75 to 2 kg (1.65 to 4.41 pounds).

The longest throw is by a woman, Martina Hellmann, in 1988 who unofficially threw it 78.14 meters (over 256 feet) but because she was a woman she was using a lighter discus; 1 kg opposed to 2 kg. That's a huge difference in weight. 

The longest throw for a man is 74.08 meters (over 243 feet) by Jürgen Schult in 1986.
