Strawman. Show me the white man who has ran the 100M in under 10 seconds! You can't, you won't. 
Why do you insist on conflating the physical with the intellectual!? Everybody and their mother knows there are physical differences between the races, be they medical or appearances. It is the gene/intellectual link that is, quite rightly, getting you in trouble.
Homo Sapiens - us today - have only been on this planet a very, very short period of time in regards to evolution. Certainly not long enough that any genetic variation between the races and intelligence will out, that cannot be controlled in some statistical manner. For example, I'll go on record as saying that I'm probably 99.99% smarter than anyone from Africa as tested by some standardized exam. 'Course when you factor in things like just trying to stay alive on pennies a day or other means of subsistence rather than making sure your subscription to Scientific American, etc. is renewed, that should come as no surprise.
