In this installment of Analyzing The Greats, I take a look at Lasse Viren, a powerhouse of distance running in the 1970s from Finland. Viren, to a lot of Americans, is known for taking down Steve Prefontaine in the 1972 Olympic 5000 meters.

Viren is a beautiful and efficient runner. His form is effortless and he looks like he's jogging even when he's running sub 5 minute miles.
