Swimming legends Michael Phelps and Grant Hackett on elite training, competitive drive, and their raw, mutual journey through depression and mental health.

Michael Phelps and Grant Hackett — Michael Phelps is the most decorated Olympian ever, with 28 medals (23 gold) and 39 world records. Grant Hackett is an Australian distance-freestyle champion who went unbeaten in the 1500m for 11 years, won 26 golds across major championships, and is now CEO of an Australian investment firm.
Tim Ferriss interviews close friends and former swimming rivals Michael Phelps and Grant Hackett together. They open by dissecting their toughest races, the obsessive training and number-tracking that made them great, and the recovery routines required to sustain years of brutal volume. The conversation then turns deeply personal, with both men describing their darkest moments with depression, anxiety, and self-harm, and how vulnerability, therapy, and supportive partners helped them. They close with reflections on books, simplifying life, and their model of male friendship and mutual support.
