Colin O’Brady’s Antarctica crossing: what “solo, unsupported” really means
Joe and Colin open with the headline feat: a 54-day solo, unsupported trek across Antarctica. Colin clarifies the route, what counts as unsupported (no resupplies, no kites), and the scale of dragging a massive sled the entire way.
- •54-day traverse across Antarctica, solo and unsupported
- •No resupplies, no wind assistance—just human power
- •Route explanation: Ronne Ice Shelf → South Pole → Ross Ice Shelf
- •Sled started at ~375 pounds, making the feat exponentially harder
- 1:19 – 4:00
Maps, projections, and flat-Earth trolling: Antarctica as internet battleground
They detour into how Antarctica looks “huge” on maps and how that fuels misconceptions. Colin shares real-life encounters and online trolling from flat-Earthers, including claims about an edge, a wall, or a hidden crew.
- •Map projection confusion vs Antarctica’s actual geometry
- •Flat-Earth questions: ‘the hole,’ ‘the edge,’ ‘the wall’
- •Social media trolling and conspiracy narratives
- •How Colin filmed solo content (tripod/timer)
- 4:00 – 4:51
Why it was called ‘The Impossible First’: risk, history, and the food/fuel math problem
Colin explains why previous attempts failed and why the expedition was labeled ‘impossible.’ The central constraint wasn’t only toughness—it was the logistics equation of carrying enough food and fuel while still being able to pull the sled.
- •Past attempts, including a recent fatality near the finish
- •Core constraint: food + fuel weight vs pullability
- •Fuel needed to melt snow into drinkable water
- •Starting sled weight and why the first day was nearly a deal-breaker
- 4:51 – 6:59
Hour one breakdown: the mental shock of starting and barely reaching the first waypoint
Colin describes being dropped off alone, immediately overwhelmed, and calling his wife while crying—before he’d even reached the ‘real’ start point. He frames it as a collision between long planning and instant physical reality.
- •Emotional collapse within the first hour in extreme cold
- •First waypoint marked the true start—he hadn’t reached it yet
- •Support call with his wife to reset focus
- •Magnitude of isolation and conditions hits immediately
- 6:59 – 10:23
Training to pull ‘heavy shit’: strength coach Mike MacAskill and extreme prep drills
Colin details how he trained specifically for sled hauling and cold stress. He highlights coach Mike MacAskill’s record-setting feats and the training methods combining strength, cold exposure, and fine-motor tasks under stress.
- •Gaining ~20 pounds for survival and performance
- •Coach Mike MacAskill’s endurance/strength records
- •Cold-adaptation drills: ice buckets + high heart rate + dexterity tasks
- •Training framed as mental preparedness for life-or-death tent scenarios
- 10:23 – 13:19
Tent storms and survival mechanics: winds, repairs, batteries, and solar power
They get into the practical survival details: setting up a tent in brutal winds and temperatures, and how close small failures come to ending the expedition. Colin explains battery management in extreme cold and how 24-hour daylight enabled solar charging.
- •High-stakes tent setup: if it blows away, expedition likely ends
- •Patch/sewing kits help—but major tent failure is catastrophic
- •Keeping camera batteries warm against skin in subzero temps
- •Solar panels + 24-hour daylight to keep devices charged
- 13:19 – 16:29
Navigation in whiteouts and the psychology of silence: flow states and Vipassana parallels
Colin describes long, silent days with limited visibility, often navigating by compass while staring down for hours. He connects the isolation to meditation practice and explains learning to intentionally trigger deep flow states for sustained performance.
- •Whiteout travel: can’t see a step ahead, rely on compass bearing
- •13+ hours per day pulling the sled in near-total silence
- •Prior Vipassana retreats as preparation for extended solitude
- •Developing the ability to ‘trigger’ flow state for days at a time
- 16:29 – 19:24
Water, altitude, and daily systems: melting snow for 6 liters a day at 9,300 feet
They unpack the daily routine: boiling snow into water for hours, carrying large amounts of fuel, and coping with Antarctica’s dryness and altitude. Colin also explains altitude training using a simulated altitude room in Portland.
- •Boiling/melting snow ~3–4 hours daily
- •~6 liters of water per day requirement
- •Antarctica as the largest desert; South Pole ~9,300 ft elevation
- •Altitude room training to simulate up to ~14,000 ft
- 19:24 – 21:13
The endgame: running low on supplies and the 32-hour, 77-mile finishing push
Colin recounts deciding to compress the final days into a single continuous push. He describes the psychological lock-in, the minimal remaining food, and the surreal finish with no audience—followed by the logistical delay of extraction.
- •Shift from 9–10 miles/day early to 20–25 miles/day late
- •Choosing a one-shot finish: 32 hours continuous, 77 miles
- •Near-empty food/fuel at the end; ‘made it right before it ran out’
- •Finish with no one present; extraction took several days
- 21:13 – 22:37
Head-to-head with another elite explorer: starting one mile apart and ‘winning the race’
Colin explains the parallel attempt by an extremely experienced British special forces/polar explorer. They started close together, Colin caught him by day six, and finished roughly 70 miles and about 2.5 days ahead.
- •Another serious contender attempted simultaneously
- •Early psychological pressure seeing the other trek away
- •Colin passes around day six and never sees him again until the end
- •Finishes ~70 miles and ~2.5 days ahead; waits to congratulate him
- 22:37 – 25:47
The unglamorous realities: one set of clothes, bathroom logistics, and Leave No Trace rules
The conversation turns to the gritty details: minimal clothing to save weight and how toileting works in extreme cold. Colin also describes environmental rules near the South Pole requiring human waste to be packed out.
- •No extra underwear/clothes to maximize food and fuel
- •Bathroom routine: holes outside when calm; vestibule method when storming
- •Special conservation rule near South Pole: pack out waste
- •Added ‘weight’ during that section from carrying waste bags
- 25:47 – 41:13
Engineering nutrition for ‘impossible’: custom whole-food bars, calorie deficits, and edible-when-frozen design
Colin explains how nutrition became a decisive edge: extensive testing, custom bar formulation, and balancing calories with sled weight. They discuss fat density, why coconut oil helped prevent rock-hard freezing, and how he stayed healthy despite a major calorie deficit.
- •Year-long testing: blood work, VO2, physiology profiling
- •Custom ‘Colm Bar’ designed for macros + micronutrients
- •~7,000 calories/day consumed vs ~10,000 burned; constant hunger
- •High-fat strategy + coconut oil to remain chewable in deep cold
- 41:13 – 47:20
Gear and cold injury management: ‘If you sweat, you die,’ layering, tape, and superglue fixes
They dive into clothing systems, sweat management, and frostbite prevention. Colin describes layer stripping, the big puffy jacket for stops, face taping for wind-prick injuries, and using superglue to seal cracked fingers.
- •Polar maxim: sweating then stopping can freeze clothing to your body
- •Layer strategy: stay just warm enough while moving; add puffy when stopped
- •Face protection: KT tape + Vaseline/ChapStick; goggles and full masks
- •Finger cracks treated with superglue; small cold injuries managed early
- 47:20 – 50:04
Purpose and mindset: turning doubt into momentum and building ‘art projects’ that inspire
Colin frames endurance feats as creative work meant to inspire others—especially students following along as curriculum. He emphasizes being human (fear, doubt) while developing the ability to redirect emotions into forward motion through meaning and mission.
- •Nonprofit/education angle: classrooms learning climate and science
- •Identity shift: athlete to ‘artist’ with endurance as the canvas
- •Using purpose to push through the worst moments
- •Belief that mental ‘muscle’ is the key differentiator
- 50:04 – 1:16:42
Origin story: the Thailand fire, recovery with his mother’s help, and winning his first triathlon
Colin shares the formative trauma that shaped his mindset: a severe burn accident in Thailand and a long recovery. His mother’s relentless positivity led to a triathlon goal, culminating in him unexpectedly winning his first-ever triathlon and launching a pro career.
- •Accident: flaming jump rope ignites him; ~25% severe burns
- •Months in a makeshift hospital setting; told he might not walk normally
- •Mother’s daily goal-setting: first step → increasing steps
- •18 months later: wins the Chicago Triathlon (first triathlon ever) and turns pro
- 1:16:42 – 1:31:02
Everest and the Explorer’s Grand Slam: ladders, death-zone risks, traffic jams, and near-disaster moments
The conversation expands to Colin’s prior record: climbing the seven summits plus the poles in record time, including Everest. He describes Khumbu ladders over crevasses, summit-day fatalities, unclipping to pass crowds, and a ‘black hand’ scare that turned out to be hand-warmer residue.
- •Explorer’s Grand Slam speed attempt: seven summits + poles (139 days)
- •Khumbu Icefall ladders: extreme exposure and repeated crossings
- •Everest summit day: crowding, unclipping from fixed rope to avoid traffic jam risk
- •Hand ‘frostbite’ scare was actually chemical hand-warmer residue; people died that day
- 1:31:02 – 1:42:38
After the summit: Denali sprint, long recovery timelines, and rebuilding physiology
Colin explains the post-Everest push—rushing to Denali to stack records—and the long recovery costs. He outlines monitoring metrics like HRV, resting heart rate, hormones, and bloodwork, plus recovery practices around sleep, diet, and inflammation reduction.
- •Rapid Everest-to-Denali transition to chase a second record
- •Recovery reality: months to feel normal; Antarctica recovery still ongoing
- •Monitoring: bloodwork, testosterone/hormones, resting HR, HRV, inflammation
- •Recovery tools: sleep, massage/chiro, probiotics, turmeric/magnesium, occasional cryo
- 1:42:38 – 1:49:58
Supplements, CBD, and mushrooms: inflammation, endurance aids, and cordyceps lore
Joe and Colin compare supplement approaches, focusing on inflammation control and performance. They discuss CBD dosing, curcumin/turmeric, Lion’s Mane and cordyceps, and the strange cordyceps lifecycle grown on caterpillars.
- •CBD for joint soreness, relaxation, and inflammation reduction
- •Curcumin/turmeric and whole-food supplement philosophy
- •Lion’s Mane and cordyceps for endurance and energy support
- •Cordyceps cultivation on caterpillars and Paul Stamets’ fungi insights
- 1:49:58 – 2:03:33
What’s next—and how not to die doing it: future projects, identity beyond ‘athlete,’ and closing plugs
Joe presses Colin on the danger of escalating feats; Colin argues his projects are methodical, not thrill-seeking, and he’s focused on impact through storytelling and new ventures. They discuss applying endurance mindset to business or creative paths, then close with Colin’s social links and book tease.
- •Risks of ‘one-upping’ and finding sustainable next challenges
- •Colin’s focus: share lessons via speaking, writing, and broader ventures
- •Identity beyond a single niche (not only climber/polar explorer)
- •Closing: Instagram/website, book in progress, and final thanks
