What does it take for a woman to break the 4-minute mile? In this exclusive and groundbreaking interview, Dr. Andy Jones—one of the world’s leading exercise physiologists and the mastermind behind Kipchoge’s sub-two-hour marathon—reveals the science, strategy, and secrets behind Nike’s latest audacious project: Breaking4.

Dr. Jones has worked with legends like Paula Radcliffe and Eliud Kipchoge, and now, he’s applying decades of research and experience to help Faith Kipyegon achieve what was once thought impossible: the first sub-4-minute mile by a woman.
