Modern Expeditions Don’t Compare to Shackleton’s Era

O'Brady reflects on how modern gear and technology made his Antarctic crossing far easier than what explorers like Shackleton endured. He emphasizes that today’s adventurers have no excuse not to push limits given their advantages.

Had GPS, Gore-Tex, and satellite communication—tools unavailable to early explorers.
Shackleton’s team spent months stranded on sea ice with minimal supplies.
Walking in seal skins and oil-lit ships was infinitely more grueling than modern polar travel.
Considers himself lucky and views past explorers as a 'different breed of human'.

“You got GPS out here. You got Gore-Tex, you've got like these boots that are molded to your feet.”
Colin O'Brady · 03:45

“There's just a different breed of human 100 plus years ago.”

The 12-Hour Walk: A Mental Reset Through Solitude

O'Brady explains the concept behind his '12-Hour Walk'—a day-long solo walk without distractions, designed to break mental inertia and reconnect with inner clarity. It originated from his post-pandemic emotional slump and the need to reclaim mental strength.

Inspired by the mental clarity he gained during his Antarctic crossing.
Designed as a way to escape digital overload and mental stagnation.
Involves 12 hours of walking in silence, phone on airplane mode, no podcasts or music.
Accessible to anyone—can be adapted based on fitness level or location.

“I say to my wife, 'Look, hey, I'm going to go for a long walk tomorrow alone... 12 hours, something like that.'”
Colin O'Brady · 55:50

“You're back. You're back. Like she could just see it in my spirit that I was back.”

How to Legally Access Antarctica for Expeditions

O'Brady explains the strict regulations governing access to Antarctica, including the role of IAATO and the limited logistics available. He describes how only one company with a single plane handles most expedition drop-offs.

Antarctica is protected by an international treaty with 12 signatory countries.
IAATO regulates all scientific and exploratory activity on the continent.
Access is tightly controlled; no independent travel allowed.
Only one company (ALE) operates flights for most expeditions during the short summer window.

“There's basically one guy with one plane... that governs almost all of an expedition contacts of most of the continent.”

The Calorie Deficit Challenge in Antarctica

O'Brady details the extreme physical toll of his unsupported Antarctic crossing, where he burned 10,000 calories daily but only consumed 7,000. He explains how the math of food weight versus distance made survival a tight balance.

Burned 10,000 calories per day but ate only 7,000, creating a 3,000-calorie daily deficit.
Sled weighed 375 pounds at start—near the limit of what he could pull.
No resupplies allowed; had to carry all food and fuel from the beginning.
Finished with his 'last bite' of food—had no reserves left.

“I was eating 7,000 calories per day, but I was burning 10,000. So, I'm on a 3,000 calorie deficit from day one.”
Colin O'Brady · 44:45

“I was on my literal last bite of food when I made the crossing after 54 days.”

Frozen Tears During the First Day of the Antarctic Crossing

Colin O'Brady recounts the emotional and physical struggle on the first day of his solo Antarctic crossing, when he broke down in tears despite the extreme cold. The tears froze to his face, symbolizing both his vulnerability and the harsh reality of the journey ahead.

Started crying on day one due to the overwhelming difficulty of pulling a 375-pound sled.
Tears froze to his face in temperatures of -30 to -40 degrees Fahrenheit.
Felt like a 'pathetic loser' despite being physically prepared.
This moment became a pivotal chapter in his book titled 'Frozen Tears'.

“When I was walking across Antarctica, my solo crossing, the first day I started crying, man. I started crying because I could barely pull my…”
Colin O'Brady · 00:00

“Antarctica doesn't take it easy on you. It just freezes the tears to your face.”

Emotional Reaction to the Discovery of Shackleton’s Endurance

Colin shares his deep emotional connection to Ernest Shackleton and describes how the discovery of the Endurance ship felt like 'Christmas morning.' He expresses awe at how well-preserved the wreck was after more than a century under Antarctic ice.

Shackleton has been a personal hero and source of inspiration for O'Brady.
Was skeptical the ship could ever be found due to shifting sea ice and vast search area.
The wreck was remarkably preserved due to cold, low-oxygen waters inhibiting decay.
Seeing photos of the intact ship gave him chills and renewed admiration for polar explorers.

“It was like a kid on Christmas waking up to that news.”
Colin O'Brady · 00:30

“It was like practically like frozen in time. I mean, it's wild.”

How a Rival Pushed Him to 12-Hour Days

O'Brady recounts how racing against British explorer Captain Louis Rudd forced him to extend his daily walking time from 10 to 12 hours. This mental shift, driven by competition, was crucial to his success.

Initially planned for 10-hour days but saw Rudd walking longer.
Felt psychological pressure to match his pace despite exhaustion.
Wife calculated that 12-hour days were necessary to finish.
Both agreed the other’s presence was essential to their success.

“Unless that 12-hour day becomes your normal day... you're not even going to come close.”
Jen (wife) · 48:50

“I don't think either of us would have made it across had the other one not been there.”

Respect for Nims Purja and the Sherpa Climbing Elite

Colin discusses his admiration for Nims Purja, not just for his climbing records but for elevating Nepalese climbers who have long been overlooked. He highlights the importance of recognizing the entire team behind such feats.

Met Nims Purja on K2 and Everest expeditions and bonded over shared experiences.
Praises Nims’ physical ability and leadership in setting world records.
Emphasizes the crucial role of Sherpa climbers like Mingma David and Mingma Tenzing.
Believes the spotlight on Nepalese climbers is long overdue and transformative.

“Nims is an incredible climber but guys like Mingma David Sherpa Mingma Tenzing... are just incredible world class.”
Colin O'Brady · 05:50

“It's wonderful particularly for the country of Nepal... to not be working for other people... to be like hey like we're doing our own badass…”

Understanding Type Two Fun: Suffering That Feels Good Later

Colin introduces the concept of 'Type Two Fun'—activities that are miserable in the moment but deeply rewarding in retrospect. He contrasts it with hedonistic 'Type One Fun' and warns against 'Type Three Fun,' which is painful both during and after.

Type One Fun: Immediate pleasure (e.g., partying, skiing powder).
Type Two Fun: Hard in the moment but epic in hindsight (e.g., climbing Everest, starting a business).
Type Three Fun: Painful during and regrettable afterward—should be avoided.
The 12-hour walk is an example of Type Two Fun.

“Type two fun's not necessarily fun when you're having it, when it's happening, right? But it is epic and fun upon reflection.”

Limiting Beliefs Are Not Truths—They’re Stories We Can Rewrite

O'Brady argues that most barriers to achievement are not physical but mental—limiting beliefs we accept as facts. He emphasizes that these beliefs can be reprogrammed through action and reframing.

Limiting beliefs are not truths—they are stories we tell ourselves.
Beliefs like 'I can’t do 12 hours' can be overcome with evidence.
The 12-hour walk is designed to challenge and defeat such beliefs.
Discipline, not motivation, sustains long-term progress.

“These are not limiting facts. These are beliefs. And beliefs can be reoriented, rewritten.”
