LATELY, IAIN WARD feels like his life is like closing time at a bar. The clock strikes 2:00 AM, but nothing happens. Everybody’s waiting for the bartender to yell it’s time to go home. “You’re kind of a bit cheeky and have a pint to finish, so you just keep drinking,” Ward says.

It’s been like that for more than a year now, ever since Ward, 37, outlived the prognosis. Five years. That’s what they gave him back when he was diagnosed with terminal, stage 3 brain cancer in 2019. But from day one, from the first scan that showed a big, murderous lump in his skull, Ward hasn’t been one to pity himself.

“Yep, that’s sad,” he says about the idea that death could come soon. “But I try to stop thinking about it and try to focus on something else. I just want to live my life the best I can.”

After the diagnosis, he crowned himself the King of Chemo, created an online character behind it, and is now approaching 7 million TikTok followers.

They’ve watched him as he took on fitness challenges, one after the other, in a triumphal fuck-off to cancer. Through it all he’s had one singular goal: to raise more money for charity than any other marathon runner ever. He says, “I kind of looked at five years and thought, that’s my window.” The “luckiest unlucky man” in the world, he likes to say.

BEFORE HE LEARNED he was dying, Ward grew up in north Dublin, spending a few years outside Chicago when his dad’s job took them there. Somehow he just never settled on a path and was living in London back in 2019, teaching fitness classes, creating video-game content, and genuinely languishing with no real goal or purpose.

For a bit of extra money, he’d sign up for medical trials, and a routine MRI scan for one of them was how they found the lump. A week later, just after his 31st birthday, they cut into his skull, and then gave him the diagnosis. The average life span with his cancer, glioblastoma, was five years, but with some luck maybe he’d get a decade more.

The weight of it, the crushing knowledge that he’d probably not live into his 40s, didn’t hit him. Not yet, at least. It sounds messed up, but there was a very big part of him that thought, well, good. “I like to say I was looking to get cancer. because I was very much losing my purpose in life,” he says. The diagnosis reset everything, the lightning strike turning a nobody into a comic book character. Behold, Cancer Man. His next steps, he says, were “served on a silver platter.”

It came to him as the doctor delivered the news. Ward felt himself ready to break, the doctor looking like he wanted to give him a hug. But Ward held it together, a voice in his head telling him there was something he needed to do. “I was pleased with myself for not breaking down, and that added fuel, like, yep, keep doing that. Well done.”

IN HIS ALTER ego, Ward promised his quickly growing followers that he’d break the single-year fundraising record of 2.3 million pounds set by British minister Steve Chalke.

And they followed him through a dizzying number of marathons, with no request for donations, only the hope that he’d turn it all into social media sponsorships. It was, and still is, a novel approach to fundraising, the idea of not annoying followers with constant pleas for donations and instead getting it from the companies that have sponsored him.

In 2024, Ward ran six major marathons, and a year later did 32 half marathons in 32 days across every county in Ireland while wearing a weighted vest. He ran a double marathon, 52 miles, on a treadmill, in just 12 hours.

But it’s not just running. On his Tik-Tok and Instagram and YouTube channels, he’ll take on a new dead-lift challenge wearing his old hospital gown. Or balance one-footed on a bosu ball with a dog balanced on one shoulder. Or use a toy axe to slash a bag of popcorn labeled “world record” while dressed in a chicken outfit, which is, admittedly, less a workout and more of an attention grab.

He has also returned to teaching fitness classes, in person in London and live-streamed on his channels, once a week or more. They’re free, generally HIIT-style workouts, the point simply to get him more likes and views, which he hopes will increase sponsorships that’ll go to his fundraising goal.

The fundamental message of the King of Chemo is that exercise can do so much for mental health, even for somebody who’s already lived longer than they were supposed to. “People are always like, ‘Oh fuck off. Me running a marathon isn’t going to get me out of my depression.’ And then they do it, and it works. It is that simple. Go to the gym. Go for a run, and you will feel better.”

It’s not that he thinks he’ll be remembered for all of it, because he knows that’s not something he can control. “Leaving behind an idea is something more important,” he says. If somebody facing death every day for five years and counting can keep running, maybe us regular blokes can too; that’s what he hopes we remember when he’s gone.

All of that positivity carried him on, ignoring the anvil of mortality that the prognosis dumped into his arms. That is, until last Christmas. He’d promised his followers he’d do seven marathons in seven days, and the plan was to use that wild goal to win, he admits now, a very stupid Tik-Tok contest. He ran all day, then spent all night trying to convince random strangers to vote for him. Five marathons in, though, he wrecked his knee.

His busted knee would mean he’d have to rest up, recuperate. No chance for more marathons, maybe ever again. He found himself, for the first time, in a bout of depression.

Then one afternoon in April, Ward went out to the gym he’d built himself in his backyard and hit the weights hard. He said to himself, Ok, let’s do that again tomorrow morning. He shut down social media and lifted again the next day, and then the day after. “Slowly but surely it brought me out of that valley of sadness,” he remembers.

Now, fully back into his role as King of Chemo, he’s thinking about the long term, something that isn’t easy for someone who’s lived longer than he should’ve. His most recent MRI showed no growth of the lump, the usurper with a dagger, waiting in his head. And so at least for now he has another day, maybe many more.

So, he has a book that’s just launched, Terminally Optimistic: Finding My Life’s Purpose Through My Cancer Diagnosis. Some part of the sales will go toward his goal of breaking the record of charity donations, which he still has yet to reach and resets at the end of every single December that he reaches. “Every year is a new attempt,” he says.

Ward is also seriously considering what his girlfriend is always asking him, that they get married, have a kid, maybe a houseful. “I’m like, ‘Are you sure? I’m probably not going to be around to raise them.’ I’m an optimist but also a realist.”

It’s past closing time now. Borrowed time. On grace, some might say. For the King of Chemo, it’s a chance for one more round.
