Go the Distance: Nikki Arthur’s Journey Beyond Limits

Imagine having the strength, not just physical, but mental, to take on a 100-mile race through the rugged Alps. That’s exactly what Nikki Arthur is gearing up to do. But ultramarathons are only one part of who she is. Starting her career teaching chemistry in Scotland, Nikki has since become a vital force supporting young athletes on the Isle of Man. And those epic races? Just one of the many ways she challenges herself.

Here’s Nikki to share her incredible story:

How I started and what led me to my career

I’m from Glasgow originally, a city with a bit of grit and soul, just like me! I studied forensic and analytic chemistry for my Masters and then went on to do a postgrad in Education, teaching Chemistry with Science. After some time on the Isle of Lewis, I moved to the Isle of Man in 2014 to teach at Ramsey Grammar School.

I loved teaching, and after four years at Ramsey, I took a role at QEII High School, where I worked my way up to Director of Key Stage 4. I was hungry to grow, so I went for senior leadership roles. I applied for assistant head at Ramsey Grammar, I didn’t get the first position, but I wasn’t going to give up, so I reapplied and landed the second.

Along the way, I also joined the Isle of Man Sport Committee to help push sport forward here, which was a great experience.

But, truth be told, juggling leadership and the daily grind started to take its toll. I was burned out. It was a hard truth to face.

Then this role popped up within the Isle of Man Sport Performance Services team, working as a Student Athlete Development Coordinator. I wasn’t sure I had the “high-performance sport” experience, but I figured my skills from education were a perfect fit. I got it! And since January 2024, I’ve been lucky enough to work with some amazing young athletes through the Sport Aid Academy and Performance Development program, it’s been a game changer.

Leaving education after 15 years was massive for me, I loved teaching chemistry but staying in that world was breaking me down.

Switching to a completely new sector, taking a pay cut, and starting from scratch was terrifying but also exhilarating. It’s one of the toughest and most rewarding things I’ve ever done.

As an ultra runner, yep, I ran 268 miles in one race, I’m used to pushing through pain, uncertainty, and exhaustion. I bring that mindset to my work every day.

I get to work with some of the most inspiring young athletes on the island. Being there for their highs and lows and knowing I’m part of their support team feels incredible.I feel valued by my team, by the athletes, and by the parents. That’s something I really missed in education.

The Isle of Man sporting community is huge and full of heart. I’m so proud to be part of it.

And running ultra races? I LOVE the hardship, the problem-solving, the adventure, the wild environment, but like on the island, it’s the community that keeps me coming back again and again.

Advice for other women starting out

Take risks. Shake things up. You belong. Find your allies and celebrate them loudly.

I’ve been lucky in male-dominated sports like boxing and ultra running to find respect and support, not just “the girl in the race” but a true competitor. I know not everyone’s experience is like this, and that needs to change.

Goals for the future

In August 2025, I’m running a 100-mile race in the Alps: the UTMB. This race lit a fire in me to test my limits on long distances, and I’m excited to put the Isle of Man on the map in the mountains.

I want to grow trail running for women on the island. I recently organised a trail run for International Women in Trail Running Day, and it felt amazing. With Isle of Man Sport, we’re working towards being the world’s leading talent identification team by 2029, it’s an ambitious goal, but I’m all in to help our athletes shine.

The photos below are from the Montane Winter Spine Race… known as Britain’s toughest race. A brutal 268-mile non-stop challenge I completed in January 2025. I finished third female, battling through Covid, bladder infections, and extreme sleep deprivation over 103 hours.

That race unlocked a whole new level of mental and physical strength in me. Sharing the start line with every competitor was humbling and inspiring.

Feeling inspired? Yep us too. Nikki is nothing short of a powerhouse. Tackling ultramarathons demands incredible stamina, grit, and sheer determination, qualities she embodies every step of the way. We love that she highlights that growth often comes from pushing through discomfort, and that when women lift each other up, they become an unstoppable force. Amen! 

We’re proud to feature Nikki in our PowerWomen series and can’t wait to see her conquer the UTMB.
