JD Tremblay

00:00 — Introduction

Dr. Barrett introduces JD Tremblay, one of only three people in the world to complete the Epic Deca — 10 Ironman triathlons across six Hawaiian Islands in 10 consecutive days — and previews the conversation’s arc from extreme endurance into Tremblay’s Hungry Warrior Academy.

02:19 — Background & Professional Journey

Tremblay describes growing up French Canadian in northern Quebec, joining the military at 17, and later earning an integrated engineering degree at Western University — a rare program held by fewer than 200 people worldwide. He credits the military not with instilling discipline directly, but with giving him structure and systems, from which discipline followed as a byproduct.

04:14 — How the Epic Deca Came About

Tremblay explains he purchased his race spot from an injured friend, Joe Jafe, after progressing through a first Ironman, an Ultraman, and other endurance events. The Epic Deca was a one-time, doubled-distance version of the annual “Epic Five” event, run in 2022 to mark that race’s 10th anniversary. Of 10 registrants, 6 started and only 3 finished.

08:24 — Course Format & Caloric Demands

Each day replicated a full Ironman — roughly 2.4 miles of swimming, 112 miles of cycling, and a marathon run — with Garmin data showing average daily energy expenditure of over 10,000 calories. Race days ran 15–20 hours, leaving only about 24 hours total for travel, gear prep, and the next start line.

10:05 — Sleep Deprivation Strategy

Tremblay slept in 12–15 minute increments in the back of a rental van to avoid injury from complete sleep deprivation, deliberately varying nap timing throughout the day so his brain would not habituate to a fixed sleep schedule.

11:55 — The 80% Psychological Framework

Tremblay argues the event was roughly 80% psychological and 20% physical, citing research that the brain consumes a disproportionate share of the body’s energy even during rest — supporting his view that cognitive load, not muscular fatigue, is the primary limiter in extreme endurance.

15:13 — Three Stages of Breakdown

He outlines three distinct phases of the race: a physical collapse after the fourth Ironman (his legs seized, requiring a wheelchair at the airport); a psychological phase after the eighth Ironman involving conflict with event organizers and threats of disqualification; and a final “transcending state” marked by total loss of physical sensation.

17:04 — Induced Peripheral Neuropathy

Tremblay describes losing all sensation in his body after day 10, testing it by sitting through a 5.5-hour tattoo session without feeling any pain, and taking over six months to fully regain normal sensation. Dr. Barrett notes this is, in effect, an induced peripheral neuropathy — a novel presentation relative to the hundreds of documented neuropathy types in his own 30-year clinical practice.

20:52 — Nutrition Strategy

To minimize digestion time during the race, Tremblay followed a strict vegan approach built around fruit, shakes, one daily serving of oatmeal, and seeds for micronutrients, supplemented with Precision Fuel and Hydration products for carbohydrate (glucose) and sodium needs. He is clear the approach was built for racing efficiency, not as a general endorsement of veganism.

23:16 — Hardest Discipline: Swim, Bike, or Run

Tremblay found cycling personally the most difficult (he considers himself a weaker cyclist), while running was the hardest on his body due to cumulative pounding and inadequate sleep. Swimming, by contrast, was his most relaxing segment.

24:36 — Mental Games & Shark Preparation

His core mental strategy was breaking the event into discrete steps — swim, bike, run — rather than thinking about the race as a whole. To remove uncertainty from ocean swimming, he paid professionals two weeks before the event to accompany him into shark-populated water and train him on shark behavior and reaction protocols in advance.

28:20 — From Epic Deca to a Book to an Academy

After the race, Tremblay wrote the bestselling book “Hunger for More in Life” (published in French, English, and Spanish), which led directly to founding the Hungry Warrior Academy.

29:19 — Hungry Warrior Academy: Structure

The academy offers online courses, one-on-one coaching packages, and in-person retreats. Tremblay, who is also a trained naturopath, positions the program’s approach as fact- and logic-based rather than the high-pressure, profanity-driven style common in men’s coaching.

30:44 — Sponsor: BBack

Dr. Barrett reviews the BBack 0524 shoe — classified as a medical device in Europe — describing pain-free running without an orthotic device. Discount code POI10 for 10% off at BBackWorld.us.

31:43 — Who the Academy Serves

The Hungry Warrior Academy works exclusively with men, given its in-person, male-coached retreat model, while Tremblay’s separate clinic practice serves all clients regardless of gender.

32:30 — Demographic & Philosophy

Tremblay describes the typical client as defined by desire for transformation rather than wealth or education — often a “broken man” who has lost hope after being failed by a system. He references Viktor Frankl’s “Man’s Search for Meaning” on the role of purpose in resilience, and is candid about his own history of failure as the basis for his credibility with clients.

35:40 — Outcomes & Timeline

Program length varies by client need, from a single weekend to as long as a year. Tremblay reports a 100% success rate across financial and weight-loss goals, citing one client who progressed from an inability to articulate his goals to signing a $50 million business deal after a year in the program.

 

 

37:53 — No Psychedelic-Like States During the Race

Tremblay clarifies he did not experience hallucinatory or psychedelic-like states during the Epic Deca, describing the experience instead as comparatively restful next to his military and firefighting background, and notes he proactively cut off contact with negative influences before the race began.

39:56 — Cold Water Immersion & IISA

Tremblay is vice president of the Canadian chapter of the IISA (International Ice Swimming Association) and discusses using cold exposure (jumping in snow at temperatures near -30°C) to manage a period of depression during his transition from military to civilian life. Ice swimming requires water at 5°C (about 41°F) or colder.

43:00 — The Turning Point Behind the Academy

The pivotal moment came after the race, not during it: Tremblay sold his house to help fund the roughly $100,000 cost of the Epic Deca, and describes a humbling realization — upon returning home with no money and no plan — that his accomplishment needed to be shared to help others, not treated as a personal trophy.

44:45 — Where to Find the Academy

Tremblay directs listeners to HungryWarriorAcademy.com, with the program also active on TikTok, YouTube, Facebook, and LinkedIn.
