How can we forget: you pull the Armstronglivs ‘steroid veins’. Dude, there was a high school picture on milesplit, after setting the FL record, standing between her parents, where it appeared she had veins popping out of her forehead. You think she was doing roids back then?
Besides the fact that her genetics are vascular (look at the veins popping out of her Dad’s arms in that picture), there is something you and Armstrong can’t understand (because you’ve probably never run a mile in your life); one of the physical benefits from training in heat and humidity (‘poor man’s altitude’) is that it makes the body more vascular. There are science papers in it.
