Aaron Bishop Quit Cold Turkey to Train for an Ironman Triathlon
I Couldnāt Swim 200 Yards Without Gasping. So I Quit Smoking and Signed Up for an Ironman.
That sounds backwards, I know. Most people quit smoking, then get fit, then maybe consider something extreme. I did it in reverse. I registered for Ironman Arizona, paid the $900 entry fee, and then realized I couldnāt complete a 2.4-mile swim, 112-mile bike ride, and 26.2-mile run on lungs that had been soaking in Marlboro smoke for twenty years. So I quit. Cold turkey. With a race clock ticking.
It was the most reckless and effective decision Iāve ever made.
Twenty Years of Marlboros
I started at 23, working construction in Tucson. Southern Arizona heat, dust, hard labor, and cigarettes on every break. Marlboro Reds at first because I thought I was tough. Switched to Marlboro Lights around 30 when I started coughing more than I liked. As if āLightsā were meaningfully different. They werenāt.
A pack a day, twenty years. The math is simple and ugly. Over 140,000 cigarettes. Roughly $58,000 at Arizona prices. A house full of smoke damage, two trucks with burn holes in the seats, and a set of lungs that wheezed if I climbed two flights of stairs too fast.
By 40, Iād transitioned from construction into project estimation, a desk job. Less physical labor, more sitting, more stress, more smoking. Iād sneak out to the parking lot four or five times a day. My coworkers knew. You canāt smoke a pack a day and hide it. The smell follows you like a shadow.
The Attempts
I tried quitting three times before the Ironman decision.
Attempt one, age 31: Patches. Nicoderm CQ, the full step-down program. I got through six weeks, all the way to step three at 7mg, and then a massive project blowup at work sent me back. The patches had been holding me at bay, but they couldnāt compete with a genuine crisis.
Attempt two, age 36: Chantix for four weeks. It reduced my desire to smoke, noticeably. But I developed bad insomnia and some stomach issues that made me miserable. I stopped the medication and was smoking again within ten days.
Attempt three, age 39: Cold turkey, fueled by a New Yearās resolution. Made it fourteen days. Fell off at a Super Bowl party. One beer, one cigarette, one failure.
The Ironman Idea
In September 2024, my buddy Rich completed Ironman Arizona in Tempe. I went to watch. I stood at the finish line at midnight, watching ordinary-looking people, some of them older than me, some of them heavier, cross the line after swimming, biking, and running for twelve, fourteen, sixteen hours straight.
Something clicked. Not inspiration exactly. More like shame. These people could push their bodies to the absolute limit, and I couldnāt jog a mile without wheezing. I was 42, theoretically in the prime of my life, and Iād been sitting at a desk and smoking myself into early decline for years.
The next morning, I registered for Ironman Arizona 2025. The race was in November, fourteen months away. I put $900 on my credit card. Non-refundable. That money was gone whether I showed up or not.
Then I looked at training plans online and realized what Iād committed to. The swim alone was 2.4 miles in open water. I went to the YMCA that week and tried to swim 200 yards. I made it about 150 before I grabbed the wall, gasping, chest heaving. A pack a day for twenty years had reduced my lung capacity to something pathetic. I could barely swim four lengths of a pool.
I sat in the shallow end, catching my breath, and thought: I canāt do this as a smoker. Itās physically impossible. I have to choose one or the other.
I chose the Ironman.
Going Cold Turkey
My quit date was October 1, 2024. Thirteen months before race day. I went cold turkey because I didnāt want nicotine in my system at all. I wanted my lungs to start healing immediately. Every day of recovery mattered if I was going to swim 2.4 miles in thirteen months.
I threw out my remaining Marlboros, my lighters, my ash trays. I cleaned my truck. I washed every jacket I owned. I was burning bridges on purpose. I wanted smoking to be hard to go back to.
The first three days were hell. Standard nicotine withdrawal: splitting headaches, irritability so intense my jaw ached from clenching, foggy thinking, and this restless, crawling sensation under my skin like every nerve was firing at once. I couldnāt sit still. I paced my house like an animal in a cage.
But I had something Iād never had in previous quit attempts: a concrete, non-negotiable goal. The Ironman wasnāt abstract. It was a date on a calendar, a receipt on my credit card, a training plan pinned to my wall. I couldnāt train with compromised lungs. The smoking had to go.
So when the cravings hit, and they hit hard and often those first days, Iād look at the training plan on my wall and think: 2.4 miles of swimming. 112 miles of biking. 26.2 miles of running. You canāt do any of that with Marlboro lungs.
The Hardest Moment
Day twelve. I was at a job site meeting that went sideways. A client was furious about a cost overrun, my boss was throwing me under the bus, and I spent three hours in a conference room getting blamed for things that werenāt my fault. I walked out of that meeting shaking with anger.
Every fiber of my body wanted a cigarette. Not wanted. Demanded. The craving was so intense I could feel my throat tightening, my fingers curling around an invisible cigarette. I sat in my truck in the parking lot and almost drove to the Circle K across the street.
Instead, I drove to the YMCA. I changed into swim trunks, got in the pool, and started swimming. Ugly, gasping, slow swimming. But I swam. I did 300 yards before my arms gave out. I hung on the lane rope, breathing hard, chlorine burning my eyes, and the craving was gone. Not reduced. Gone. The exertion had burned it out of my system like a fever breaking.
Thatās when I understood the connection between training and quitting. They werenāt separate goals. They were the same goal. Every workout was a quit-smoking session. Every mile in the pool or on the bike was a mile further from Marlboros.
Training and Recovery
The first three months were brutal. My lungs were healing, but slowly. I could feel the difference week to week, not day to day. In October, I could swim 300 yards. By December, 800. By February, a mile. My breathing in the water went from panicked gasping to controlled, rhythmic exhales. The tar was clearing. The tissue was recovering. It was happening.
On the bike, the progress was faster because cycling is less dependent on pure lung capacity. I started with 20-mile rides and worked up to 60 by January. My legs were strong from years of construction work. It was my engine, my lungs, that needed rebuilding.
Running was the hardest. At first, I couldnāt run a mile without walking. My lungs burned, my chest tightened, and my breathing sounded like a broken accordion. I started with a run-walk program: run two minutes, walk one minute, repeat. Slowly, over months, the running intervals got longer and the walking intervals got shorter. By March, I could run three miles continuously. By June, eight. By September, I did my first 18-mile long run.
I was slow. Iām still slow. I wasnāt trying to win the Ironman. I was trying to finish it.
Cravings During Training
The cravings didnāt stop just because I was training. They came, especially in the first six months. After a particularly hard workout, when my body was depleted and my willpower was low. During rest days, when I didnāt have training to distract me. In social situations, like watching football with buddies who smoked on the patio.
What changed was my relationship to the cravings. I stopped treating them as emergencies. They were just signals, misfires from a brain that was still rewiring itself. Iād feel the craving, acknowledge it, and let it pass. Sometimes Iād do push-ups or go for a short walk. Sometimes Iād just sit with it and wait. The cravings always passed. Usually within three to five minutes.
By month eight, they were rare. By month ten, almost nonexistent. My brain had finally accepted that nicotine wasnāt coming back.
Race Day
November 2025. Ironman Arizona. Tempe Town Lake.
I stood on the shore at 6 a.m. in a wetsuit, surrounded by 2,500 other athletes. The water was dark and cold. Thirteen months earlier, I couldnāt swim 200 yards without grabbing the wall. Now I was about to swim 2.4 miles.
The cannon went off. I dove in.
The swim took me 1 hour and 28 minutes. Slow by Ironman standards. I didnāt care. When I climbed out of the water on the other side, my lungs were tired but clear. No wheezing. No gasping. Just steady, deep breathing.
The bike took me 6 hours and 44 minutes. A hundred and twelve miles through the Arizona desert, wind in my face, sun beating down. I ate energy gels and drank water and pedaled. My lungs held.
The run was the test. A full marathon after swimming and biking for over eight hours. My legs were heavy. My feet hurt. But I ran. I walked some hills. I ran the flats. I kept moving.
I crossed the finish line at 10:47 p.m. Total time: 15 hours, 47 minutes, and 12 seconds. The announcer said the words Iād been chasing for thirteen months: āAaron Bishop, you are an Ironman.ā
I bent over, hands on knees, and cried. Not because of the race. Because fourteen months earlier, I couldnāt swim 200 yards. I couldnāt run a mile. I was a 42-year-old smoker whoād given up on his body. And now Iād just completed one of the hardest endurance events on earth.
With lungs that used to wheeze climbing stairs.
Life Now
Iām 43. Seventeen months smoke-free. Still training, though Iāve dialed it back from Ironman intensity. I swim three times a week, bike twice, run twice. I signed up for a half-Ironman in April.
My lung function, measured by spirometry at my doctorās office, has improved by about 15% since I quit. My doctor says itāll keep improving for several more years.
Iāve saved about $4,200 in cigarette money. The Ironman cost about $3,000 total including registration, travel, gear, and nutrition. So I essentially funded the whole thing with cigarette savings and came out ahead.
I gained about eight pounds initially from increased appetite, but the training burned through it. Iām actually leaner now than I was as a smoker, which I didnāt expect.
The cravings are gone. Truly gone. I donāt think about cigarettes anymore. When I smell smoke, it smells like something from a different personās life.
To Anyone Still Smoking
You donāt have to sign up for an Ironman. Thatās my brand of crazy, not yours. But find something that demands more from your body than smoking will let it give. A 5K. A hike you canāt finish yet. A sport youāve always wanted to try. Something that makes quitting not just about stopping a bad thing, but about starting a good one.
The reason Iād failed three times before wasnāt lack of willpower. It was lack of purpose. I was quitting to avoid something: disease, death, cost. This time, I was quitting to achieve something. That shift, from avoidance to pursuit, changed everything.
Give yourself something to run toward. Literally or figuratively. Make quitting the first step of something bigger, not the whole story.
You are not alone. There are millions of people whoāve been where you are, whoāve stared at a pack of cigarettes and thought, āI canāt do this.ā You can. You just need a reason thatās bigger than the craving.
Find that reason. Then lace up your shoes and go.
