 Within East Africa, whether it's Kenya, Rwanda, Ethiopia, Eritrea, most of these guys are along that rift valley. So they do train at altitude. I know when we lived in Rwanda, we were at about 6,700 feet. On top of that, it's not only just the altitude, it's just their natural God-given gift to be able to race at this level. So it's not a matter of, do they have the talent?
