​About Jeff Browning

​I'm an endurance coach, ultra athlete, designer, husband and father of three kids. I live to run in wild places, as well as fighting to protect them.  

I found running naturally by roaming free as a kid, exploring our 700-acre farm in Missouri. No matter the weather — I was always moving. And that hasn’t changed. For me, running through the wild is pure. It provides the remedy to this fast-paced, always-connected world of ours.

Why Bronco Billy?

In my early ultra days, a running buddy came up with the nickname due to my tendency to yell "Yee-Haw" and "Giddyup" when my stoke was high on a running adventure. Others started calling me it too and it just kinda stuck.

I’m also a tinkerer. Gear can always be better, lighter — more dialed. I can often be found cutting or drilling my shoes, charting their weight, or begging my wife to break out her sewing machine to test out a new idea. Over 21 years in the graphic design industry has fine-tuned my creative skills; while 17 years of competitive ultra running and over 100 ultramarathon finishes have polished my training and racing strategies — including nutrition. I believe in organic whole foods (primal/bulletproof/LCHF), that fat is the optimum fuel, and that Hippocrates was spot on when he said, “Let food be thy medicine and medicine be thy food.” 

Running thousands of miles through the world’s untamed lands has also instilled in me a passion for conservation — helping to protect the places we play. I was thrilled to help celebrate a conservation win in Chile by running through the new Patagonia National Park as documented in the short film, Mile for Mile.
