Jeff Browning

About

Jeff Browning, universally known as "Bronco Billy," is an American ultrarunner and coach from Bend, Oregon who holds the record for most 100-mile wins in history — more than 30 victories at the distance across a career spanning over 25 years. A seven-time finisher and multiple winner of the Hardrock 100 (one of the sport's most technically demanding races), he has also won the HURT 100, Bighorn 100, Bear 100, Moab 240, and Tarawera 100, among dozens of other titles. He continues to compete at the highest level well into his fifties, embodying the principle that ultra performance can peak late in life.
