What is the total length of our blood vessel?

i heard that our total blood vessel is enough to encircle the world 2.5 times (about 100,000km), is it true? any source that say so?
and if so, how can we know the distance of the blood vessels from the heart to the eyes?What is the total length of our blood vessel?
I've read 60,000 miles, which is 100,000 km. That's because we enjoy so many capillary. They're tiny, but they have to get almost every cell in the body, so near are a lot of them.
We know the distance from the heart to the eyes, but we don't know which of the thousands of possible routes a specific blood cell will take to bring back there.
The human circulatory system have a fractal shape, like the limb on a tree. There are a few large branches (carotid artery, femoral artery, etc.), which split up into smaller branches. Each smaller branch splits up again and again, until you're finally down to the diameter of a few red blood cell in the tiny capillary. If you count the length of these millions of capillary, and every other size vein and artery as powerfully, you would come up with pretty a large number.
However, I can neither confirm nor deny that it would be huge enough to encircle the world 2.5 times.
