Welcome back or welcome to the Single Trek podcast. I'm your host Finn Melanson and in this episode

we're talking with Baron Heinrich, a professor emeritus in the biology department at the

University of Vermont where he made major contributions in the study of the physiological,

ecological, and behavioral adaptations of animals and plants to their physical environments.

He's also regarded as one of the best American ultramarathoners of all time.

In the early to mid-1980s, for example, he set records in the Road 100K, Road 100 Mile,

and 24-hour track events.

Later in life, he published two books that have received widespread acclaim

in our community, one titled Why We Run, the other titled Racing the Clock. And these two

books, as well as Bairn's running career and lifestyle, serve as the basis of our conversation.

Before we get started, though, this episode is brought to you by Rabbit, makers of my favorite trail running

apparel. If you're in the market for new kit, head over to their website and use code

Burned Heinrich, it's a pleasure to have you on the single track podcast. And before we get started,

I just wanted to thank you for the opportunity to enjoy this conversation in your beautiful

mountain cabin in these northwestern Maine woods. I can't think of a place I'd rather be right now.

This is incredibly peaceful. Well, thank you very much, Finn, for having me.

I'm glad you're here.

So I'll preface this in the pre-roll of this episode as well.

You are widely regarded as one of, if not the greatest American ultramarathoners,

at least during that time period of the early to mid-80s.

You had records at certain times in the 100K, 100-mile, 24-hour events, among other accolades.
