This is a composite story, drawn from common experiences shared in the schizophrenia community. It does not depict a real individual.
The first time I ran more than a mile without stopping, I was thirty-four years old, nine years on antipsychotics, and convinced I was going to throw up by the second telephone pole. The mile was a flat half-mile loop in a city park near my apartment in Minneapolis. I came home and lay on the floor for twenty minutes. Two years later, I crossed the finish line of the Twin Cities Marathon at 5 hours 41 minutes. This is a story about that two years.
Running a marathon did not cure my schizophrenia, but it taught me that my body was something I could trust again — and that turned out to matter more than I had expected.
Why I started
I had been on a stable regimen for several years and had gained about thirty-five pounds since starting medication. My A1C was creeping up. My primary care doctor had used the phrase "metabolic syndrome" in a way that finally registered. The exercise advice I had been given for years was the standard stuff — "thirty minutes of movement most days." I had ignored it.
What changed was a small comment from my therapist. She said, "What if you trained for something specific, instead of trying to exercise in general?" She did not specifically suggest a marathon. That was my own bad idea. But the framing — train for a specific event — made the whole project feel less like an open-ended chore and more like a project with a deadline.
What the science actually says
Before I committed, I did some reading. The evidence on aerobic exercise for people with schizophrenia is genuinely good. A frequently cited meta-analysis by Firth et al. (Schizophrenia Bulletin, 2017, available on PubMed Central) found that aerobic exercise programs of about 90 minutes per week were associated with measurable improvements in symptoms, cognition, and quality of life. Other studies have linked exercise to small but real increases in hippocampal volume in people with schizophrenia.
Exercise is not a substitute for medication, and it is not going to cure psychosis. But the evidence that consistent aerobic exercise modestly reduces negative and cognitive symptoms is strong enough that the NICE schizophrenia guideline recommends physical activity as part of routine care.

The first six months
I followed a slow, beginner-friendly couch-to-5k programme. Three days a week. Walk-run intervals. The first six weeks were uncomfortable but not awful. By week eight I could run thirty minutes without stopping.
What I noticed during those first months had less to do with weight (which dropped slowly) and more to do with sleep. My sleep had been mediocre for years; running every other day made it markedly better. My voices, which had not been a major problem on medication, did not change much. My mood, which had been low-grade flat for a long time, lifted a little.
The boring middle
From month six to month eighteen, I built up mileage slowly. I joined a beginner-friendly running club that met on Saturday mornings. I told one of the coaches about my diagnosis on the third week, partly because she asked about my medications when we were talking about hydration, and partly because I wanted at least one person at the club to know.
The middle stretch is where most marathon training stories get glossed over because nothing dramatic happens. Things that did matter:
- Sleep was non-negotiable. The longer my training runs got, the more sleep I needed. I started turning down social plans on the night before long runs and felt no guilt about it.
- Hydration interacts with medication. Some antipsychotics — particularly lithium augmentation, which I am not on, but also others — have significant interactions with hydration and electrolyte balance. I talked to my psychiatrist about this. She and my GP coordinated.
- Heat intolerance was real. Several antipsychotics impair the body's ability to regulate temperature. I learned to run early in the morning in summer and to back off when it was hot.
- Energy crashes were not the same as relapses. I had to learn the difference between the very real fatigue of a 16-mile training run and the early signals of psychosis. They overlap. Tracking helped.
Two near-misses
Twice during the eighteen months I came close to derailing the project. The first was at month ten, when I sprained my ankle stepping off a curb wrong. I lost six weeks of training and had to be talked out of giving up by my therapist, the running coach, and one persistent friend who kept telling me I was being dramatic.
The second was at month fourteen, when a stretch of bad sleep set off the kind of low-grade prodromal symptoms I know well. I called my psychiatrist. We did not change my medication. I cut my training mileage in half for two weeks, prioritised sleep, and the symptoms quietly resolved. I did not get hospitalised. The training, oddly, kept me steady through a window where in the past I might have slipped.
Race day
The morning of the marathon was cold and grey and I did not sleep well. I took my medication on schedule, ate the breakfast I had practised eating before long runs, and lined up at the start corral with thousands of strangers. I was 36 years old. I had been on antipsychotics for twelve years. I was about to run 26.2 miles.
The race itself was long, slow, and mostly uneventful. I walked the last three miles. My family met me at the finish line. My mother cried. I cried, but quietly, because I was very tired. The medal was the cheap aluminium kind that all marathon medals are. I have it on my bookshelf.
What changed and what didn't
After the marathon I lost about twenty-five pounds total over the two years of training. My A1C came back into normal range. My resting heart rate dropped. My sleep is better than it was. My mood is better than it was. My medication is the same.
What did not change: I still have schizophrenia. I still hear voices when stressed. I still have negative symptoms — flat affect, low motivation on days when I am not training for something. The marathon did not erase any of this. But the experience of training for and finishing it has given me a kind of structural belief in my own body that I did not have at twenty-four. That belief is its own sort of medicine.
What I would tell someone thinking about a big physical project
- Talk to your prescriber and GP first. Some medications interact with intense exercise; some have specific cautions in heat, dehydration, or with rapid weight change.
- Start ridiculously slowly. Couch-to-5k is the gold standard for a reason.
- Prioritise sleep over mileage. Always.
- Find one person — a coach, a friend, a peer — who knows what you are doing. Solo training in serious mental illness is a relapse risk.
- Track patterns, not perfection. Missing a workout is not a relapse.
- Pick a goal you actually care about. A 5k, a hiking trail, a swim — it does not have to be a marathon.
- Be kind to your body. The body that carried you through years of psychosis deserves a little tenderness.
I am training for a half-marathon now. The pace is slower. The stakes feel lower. The reasons are the same.
