The term man (from Proto-Germanic *mannaz or *manwaz "man, person") and words derived from it can designate any or even all of the human race regardless of their sex or age. The word developed into Old English man, mann meaning primarily "adult male human" but secondarily capable of designating a person of unspecified gender, "someone, one" or humanity at large (cf. also German Mann, Old Norse maðr, Gothic manna "man"). More restricted English terms for an adult male were wer (cgn Latin vir) and guma (cgn Latin homo; survives as the second element in "bridegroom").

So the root of the word man comes from the proto-germanic word manwaz meaning person. so therefore if you ignore the general assosiation of the word with meaning adult male and take it at its root value the 'race of man' means race of people, no gender implied.
