Message From The Founder
My Journey to Endurance
Longer Version:
I grew up in Central New York and started to dabble in running in 2012 (at the time a sophomore shot putter on the high school track team). I was 5' 10" and tipping the scale at 256lbs, and gaining weight in a hurry. But from my first days as a thrower for the high school team, I marveled at every runner out on the track. I could not imagine running as fast or as far as they all were, but knew I wanted to get there.
Hey, you there!
Yeah, you! Fill out the message box below with any thoughts, questions and inquiries. I will get back to you as soon as I can.

Stay Beautiful,
-Greg
Short Version: Basically I am a guy who likes running.
A couple of seasons later in the Fall of 2013, I was coerced to join the school Cross Country team, at the time still unsure if I would actually have the ability to finish a 5K race. Week in and week out, hauling myself to the finish line of whatever race we were at proved to be the hardest thing I had ever done in my life. There was an addictive quality to the experience of thinking I had no chance of finishing, but somehow getting it done. And that was it for me. I could never let go of the thing that I had worked so hard to succeed at. Nothing had ever made me feel more free and alive than running.
​
Now I am a coach, marathoner, mountain dweller, fitness nerd, and hardcore outdoor-appreciator. I live high up in the mountains of Colorado with my adventure partner, Shae, and our dogs, Moose and Minnow.
