The ultimate guide to navigating your first ultramarathon

So, what exactly is an ultramarathon? An ultramarathon is any distance which is further than the 26.2 miles (or 42.2km) of a marathon. Of late, this unique and exhilarating discipline has begun to rival the marathon in popularity. And, getting out on the trails, or in the mountains, is definitely the coolest way to take on a run of this length.

However, increasing your distance and time out running also increases the opportunity for things to go wrong. Or, as I like to see it, gives you more opportunity to problem-solve, grow, and conquer.

I hope this guide will help you to understand that ultramarathons shouldn’t be overwhelming or complicated. Instead, ultra running is about doing the basics well and keeping it simple. My guide is designed to give you the foundations for longevity and enjoyment, while being able to climb your own individual peaks.

No risk, no story: how to choose your first ultramarathon

When you google ultramarathons, you may well become overwhelmed by the sheer number of events that exist. Track? Trail? Mountains? Roads? 24 hours? 100km? 100 miles? There’s a lot out there, and this can be overwhelming, terrifying, and exciting all at the same time.

When I was searching for my first ultramarathon event I was 15 years old and the choice was very limited - there was only one race that would let a 15-year-old run. So picking was pretty easy and my first ultramarathon was a 100km event. However, your story doesn’t have to be quite so 0 to 100.

If you’re picking your first ultramarathon then my biggest piece of advice is to ask yourself some simple questions:

  1. What excites you?
  2. What can you realistically complete? 
  3. What time frame do you have to prepare?

If you live in the city, and don't have the time or means to get out onto the trails or into the mountains, then perhaps pick a race that’s closer to home and more accessible.

Ultimately though, when it comes to choosing your first ultramarathon you should find a race that really lights a fire in you, gives you goosebumps - then jump! No risk, no story.

Ultramarathon training: leave the numbers behind

Now you’ve got your race, it’s time to train! This should be the fun part. As cliche as it sounds, 'it’s about the journey not the destination'. And, something I’ve always prided myself on throughout my career is consistency and my enjoyment of training.

When I trained for my first ultramarathon I only ran easy. No workouts, no programs. I ran with my Dad, before or after school. I rested if I felt tired or didn’t have time, and I didn’t stress about the numbers or the event. Instead, I choose to enjoy the feeling each day of getting 1% closer to being in the best position to enjoy race day.  

So, if you’re training for your first ultramarathon then I suggest finding comfort and routine in getting up and getting out, before you start thinking about your pace, heart rate, hours trained, or other metrics. When you’ve got this consistency and routine, then you can begin to add other ‘workouts’ to your schedule.

That said, when it comes to ultra running, always prioritise the joy and the good feelings, and always remember that in this sport, the numbers don’t define you. If you have a good run and see that your pace was a little slower, that doesn’t make that run less good.

Now eight years into the sport I still have to check my headspace and ask: why am I running and who I am running for? I run for me, and the feeling it gives me, not to impress others with numbers.  

Even now, my training consists of easy jogging 5 days a week. These are the foundations of my running. They strengthen my cardiovascular system and develop the muscles required for ultramarathons.

In terms of pace, these should be runs where you are breathing easily, can hold a conversation, and feel like you can keep going even when you stop. That's when you know you’re on the right path.

Ultramarathon training: protect your body and it will protect you

Ok, so we’ve booked the race, and we’ve started training, but suddenly we feel pain. Here is where the ultra running community - although amazing - can be your biggest vice. There seems to be an unwritten award for the person at each start line with the most broken bones, or tape holding their limbs together, or who’s taken the most painkillers.

Generally, this is because they couldn't handle the process and short term pain of resting when injury beckons during training. Don’t make this mistake! My advice? If it hurts, stop.

We want to enjoy running, it’s meant to be fun and there is absolutely nothing wrong with cutting a run short or not starting at all. This is a form of self-love that I advocate and have had to learn the hard way. I fell into the process of always justifying pain as “my muscles adapting” or “when you train a-lot, this is normal”.

Of course there will be stiffness and there will be mental fatigue on runs. You may even be bonking; where your mind and body is just telling you stop. It’s in these moments that I employ the 10 minute rule:

  • If I feel a bit stiff / sore before I run, I’ll go out and just do 10 mins
  • If I’m still not feeling great, I’ll turn around - at least I got 10 mins in and tried
  • If I'm on the verge of bonking I give myself 10 mins to resurrect the situation: this could be eating, sitting down, taking on water, listening to music, or taking deep breaths

You’ll learn more about your body over time and you’ll appreciate it more than ever as you navigate through your first ultramarathon. Listen to your body, use the 10 minute rule and you can’t go too far wrong. Oh, and take any advice from the ultra running community with a pinch of salt!

Ultramarathon mindset: create a tool kit for the mind

The last, but most important thing when it comes to training, is the mind. We train the body and expect big things from ourselves, but if you’re running an ultramarathon then we must also train and treat the mind with the same love and support.

As I mentioned at the start, taking on a distance further than 26.2 miles will challenge you in many ways. I’m not going to paint an unrealistic picture of sunshine, rainbows, and unicorns. Yes, those moments happen, but there is also darkness, rain and a whole lot of doubt. So, what I’ve learned is to have a tool kit for the mind, and ways to bring myself out of those situations.

My tool kit includes:

  • Mantras
  • Gratitude 
  • Food
  • People
  • Music

These are all options I use when the going gets tough, but the only way you will find what works best for you is by getting out there and trying. That way, when you feel the darkness, rain and doubt coming during the event, then you’ll be able to find the rainbows, the sunshine, and the unicorns, because you’ve trained your mind to do so.

It’s that incredible mind of yours that gave you the idea to do an ultramarathon in the first place and that endured the training to get there. And, the mind has an amazing ability to only remember the good moments. Before you know it, you’ll be back entering your next ultramarathon.

The ultramarathon community: you’ll need them, trust me

Finally, let’s talk about the ultra running community. After all, you’re going to need them and they’re going to see you, the real you. And, as the saying goes: 'if you want to go fast, go alone. If you want to go far, go together.'

Well, when you enter your first ultramarathon, you are going to join an incredible and inclusive group of humans. This whacky community wakes up before the sun rises to get their long runs in, comes in all different shapes and sizes, and can always be seen wearing the loudest clothing and widest smiles.

These are the people who’ll help you go to the toilet in the bush, or pull you back up when your stomach rejects one too many gels, and, most importantly, who will be there when you finish - whether that’s first or last.

That’s the best thing about this community - they have your back: they’ve had mine for 9 years now. Being a young female, I couldn’t think of a better group to grow up with. They’ve seen me smile, seen me win, seen me injured and sad, make mistakes and learn from them. If you’re here because you’re entering your first ultramarathon, then welcome to this special community.

You’ve made it. Now, take your time and bask in the journey of running: this is where the growth happens and the best feelings are created.

The Challenges Women Face in Running and How It Impacts Participation

Running is often lauded as one of the most accessible sports—just lace up your trainers and go. However, for many women, the barriers to participation go far beyond the logistical. While safety concerns are frequently highlighted, deeper systemic issues like access to the sport and unequal treatment are also preventing more women from running. It was a topic keenly discussed at our In Her Stride panel held at the end of November, with key members of the female running community including Sophie Power, Tasha Thompson, Rehana Mawani and Emily Shane. 

Running is often lauded as one of the most accessible sports—just lace up your trainers and go. However, for many women, the barriers to participation go far beyond the logistical. While safety concerns are frequently highlighted, deeper systemic issues like access to the sport and unequal treatment are also preventing more women from running. It was a topic keenly discussed at our In Her Stride panel held at the end of November, with key members of the female running community including Sophie Power, Tasha Thompson, Rehana Mawani and Emily Shane. 

Before we kick things off however, we should highlight that female participation in running events is growing, and this is a great thing! According to data from Let’s Do This, women in their 20s are the fastest-growing demographic in event participation this year. However despite this, women are still 16% less likely to run every week compared to men. This disparity is particularly striking given that women report higher levels of personal benefits from running, such as improved fitness, better sleep, and reduced stress.

The reasons for this are complex and personal, however we have broken down three key challenges discussed during our panel and the solutions explored that could help address them.

1. The Pressure of Pace

One of the biggest hurdles for many women is the pressure to run faster. Despite the average UK woman’s running speed of 06:37 min/km (according to Strava), most run clubs don’t cater to this with the slowest pace often around 6 minutes per km. Add to this the relentless focus on personal bests and fast times on social media, and it’s no surprise that many women feel too intimidated to join in. 

Thankfully, there are starting to be more people rebelling against this speed obsession, including our panelist, Emily Shane. Emily has been leading the charge to encourage more women to disregard pace and focus on the experience of running to drive uptake amongst women. Initiatives like events without cutoff times and more inclusive pace groups at running clubs are vital to creating a more welcoming environment and broadening the benefits of running to the experience and community. 

2. Perception of Sport in Schools

One of the topics hotly discussed was how for many girls, the barriers to enjoying physical activity start at school. Puberty, coupled with changing bodies and fluctuating emotions, can make sports feel daunting and uncomfortable for teenage girls. Research highlights this disparity: only 38% of girls enjoy sport and exercise compared to 53% of boys, and just 26% of girls feel confident in physical activity versus 43% of boys.

The panel emphasised the need to address this such as:

  • Introducing a wider variety of sports and fitness activities to cater to different interests
  • Providing more supportive and confidence-boosting PE kits.
  • Showcasing more female role models in sport to inspire young girls.

By addressing these issues at the school level, we can foster a love of sport that lasts into adulthood.

3. Treatment at Events

This is a topic that panelist Sophie Power, founder of SheRACES is incredibly knowledgeable and passionate about. Even at organised running events, women often experience unequal treatment. From “unisex: t-shirts (which are actually designed for men) to a lack of sanitary products in portaloos, these "small things" can collectively make women feel like an afterthought. Prize money inequality and rigid event policies—like no deferral options for pregnant or postpartum women—further highlight these disparities.

Thankfully, initiatives like the 50:50 campaign by Threshold (a campaign to get 50% of women at Ultra startlines vs. the current average of 30%) and the advocacy work of SheRACES are driving change, and there are many amazing event organisers such as Maverick, Threshold, Why We Run and many more, that are working hard to make their events are inclusive as possible for women. 

Despite these challenges, the panel and attendees felt overwhelmingly optimistic about the future of running for women and the benefits it brings us. Progress is being made, however we all need to add our voices to the conversation to help more women get into the sport and reap the benefits.

Here are a few helpful resources. This list isn’t exhaustive by any means, however is a good starting point for those looking for inspiration on where to start.

From Radio to Race Day: Hattie Pearson’s Path to Endurance Event Glory

Hattie Pearson is the type of person who doesn’t just dabble in fitness (or most things…!) She dives in headfirst, often with no hand-holding (except, perhaps, metaphorically). From her first triathlon in 2021 to a series of jaw-dropping endurance feats in 2024, she’s been redefining what’s possible with determination, community, and a big ‘YES’ attitude.

Hattie Pearson is the type of person who doesn’t just dabble in fitness (or most things…!) She dives in headfirst, often with no hand-holding (except, perhaps, metaphorically). From her first triathlon in 2021 to a series of jaw-dropping endurance feats in 2024, she’s been redefining what’s possible with determination, community, and a big ‘YES’ attitude.

Just say YES

Hattie’s ‘yes’ streak started when a friend and her decided to do a sprint triathlon together. “We had such a great time,” Hattie recalls, “and I was like, I want to do more of this.” That spark quickly turned into a blaze of ambition. By the following year, she was competing in Outlaw triathlons and even signing up for a full-distance Ironman—before completing her first half-distance event. “I didn’t give myself the choice to not carry on,” she says.

The Power of Community

For Hattie, discovering the 10IronWomen network—a group committed to gender parity in triathlons—was a game-changer. “It’s amazing to see a community encouraging women and non-binary folk to show up,” she explains. “Seeing others doing it made me think, I want to be a part of this.” That sense of solidarity and shared purpose has been a recurring theme, whether she’s lacing up for a winter triathlon in the Alps or a grueling ultra-marathon closer to home.

A Year of Big Goals

This year, Hattie set herself a dizzying list of challenges. She swam 500 kilometers (yep, that’s half a million meters!) and tackled a range of events, including a winter triathlon complete with ski touring, the Étape du Tour cycling challenge, and her first ultra-marathon. Each was hard in its own way—whether it was battling snowy trails with crampons or smashing out seven-and-a-half-minute miles for 13.1 miles. But for Hattie, the difficulty is the point. “Every time I achieve something I thought was impossible, I remind myself: I can do hard things.

Balance and Burnout

With goals that ambitious, fitting it all in can be a challenge. Early mornings help. “I’m one of those people who can get up at 5:00 a.m,” Hattie admits, however it also takes a lot of discipline. With her work on Hits Radio starting later in the day, she carves out time for training, dog walks, and the occasional tantrum over broken goggles. “I’ve definitely had those ‘forgetting-my-swimming-costume’ moments,” she laughs. But her key to staying motivated is simple: keep it fresh and fun. Whether it’s joining her triathlon club for training or trying a completely new event, keeping it fun and different is the secret to staying motivated and on track to reach your goals. 

Advice for Aspiring Endurance Athletes

For anyone looking to follow in her footsteps (or strokes), Hattie has this advice:

  • Be patient. Results don’t come overnight, and the journey is as important as the destination.
  • Stop comparing. “Your journey is completely your own. Social media only shows the highlights,” she reminds us.
  • Find your community. Whether it’s a running club, a neighbor for early morning jogs, or an online network, accountability and camaraderie make all the difference.

What’s Next for Hattie?

In 2025, Hattie plans to tackle her first multi-day event, the Monster Triathlon. Admittedly it is as scary as it sounds, kicking off with a 5K swim in Loch Ness, followed by a 1,000-kilometer bike ride to Windsor, and wraps up with a casual 50K run to London(!). Her goals also include more open-water swimming, trail running, and maybe—just maybe—an even bigger endurance challenge. (Though definitely not swimming the English Channel: “No way am I swimming through jellyfish without a wetsuit!”)

Hattie Pearson’s journey is more than a personal triumph. It’s a testament to the power of showing up, saying yes, and proving that with the right mindset, anything is possible. Whether you’re tackling your first 5K or dreaming of an ultra-marathon, Hattie’s story is proof that the finish line is worth the hard miles. And when you cross it? You’ve won your race—medal or not. 🏅
