​About Jeff Browning

Jeff is an endurance coach, ultra athlete, designer, husband and father of three kids. He lives to run in wild places, as well as fighting to protect them.  

He found running naturally by roaming free as a kid, exploring his family's 700-acre farm in Missouri. No matter the weather — he was always moving. And that hasn’t changed. For him, 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.

He's also a tinkerer. Gear can always be better, lighter — more dialed. He can often be found cutting or drilling his shoes, charting their weight, or begging his wife to break out her sewing machine to test out a new idea. Over 22 years in the graphic design industry has fine-tuned his creative skills; while 18 years of competitive ultra running and well over 100 ultramarathon finishes have polished his training and racing strategies — including nutrition. He believes 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 him a passion for conservation — helping to protect the places we play. He 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.
