Talos's race seems to be a running joke with Bethesda and the fans, as Bethesda seems to change it each time they're asked. They've referred to him as a Nord, an Atmoran, a Breton, an Imperial, and in TES Adventures: Reduard his skin is dark enough you could argue he's a Redguard. Wouldn't be surprised if they say he's a Khajiit next time...

Personally I think he was a Nord, given his birth name of Hjalti Early-Beard. While the same isn't a guarantee of race (i.e Lucien Lachance is an Imperial not a Breton), most of the time the name is linked to the character's race. If not that, a Breton since he was born in High Rock. Again, not a guarantee of race but usually a strong indicator.
