Ultra marathons are any running events that at the very minimum go further than the marathon distance of 42.2km. The problem is that there is no upper limit. As a result, there are now some insanely challenging events held across the globe. The distance isn’t the only problem either, as competitors are asked to wrestle with mountains, rain-forests, deserts, or extreme weather conditions.
Since they’re events that allow you to experience the world in a unique way, we’ve chosen the best ultra marathon from all 7 continents (yes, even Antarctica), and added a couple of runners up so you can explore your options.
1. Africa: Comrades Marathon

The route:
- Durban to Pietermaritzburg (or Pietermaritzburg to Durban, depending on the year)
- 87km/54 miles uphill or 90 km/56 miles downhill in a 12 hour time-limit
- Takes in ‘The Big Five’ hills with a highest elevation of 2,850ft/870m above sea level
Run it for:
This is the world’s oldest and largest ultramarathon. It was first run in 1921, and has been completed by over 300,000 runners. The current field allows for 27,500 participants. It is famous for its vibrant atmosphere and support, with school children and local folk bands cheering you along the way. The race is run in the spirit of ‘Ubuntu’, which can be translated as ‘humanity towards others’.
Runners up:
- Marathon des Sables, Morocco: 251km in the Sahara Desert
- Namib Race, Namibia: 250km in the Skeleton Coast National Park
2. Antarctica: The Last Desert

The route:
- A variety of locations on the Antarctic Peninsula, potentially including King George Island, Deception Island, and Paradise Bay
- 250km multi-stage event
- Each night sleeping on the expedition ship
Run it for:
This is the only multi-stage footrace in Antarctica. The main challenges in the polar desert are the conditions of extreme cold, high winds and sheer landscapes. Varying snow, ice and weather conditions cause the course to change each year, often at late notice. The chance to tread in the footsteps of ancient explorers and to see a variety of wildlife including whales, penguins, and seals in the untouched wilderness makes this event a rare and life-changing experience.
Runner up:
- The Arctic Ice Marathon and 100k
3. Asia: La Ultra - The High

The route:
- In the Great Himalayan range of India, starting from the Nubra Valley towards the Indus River, and finishing in the Morey Plains of the Changtang plateau
- 333km/207 miles in 72 hour time limit. Including three 17,500ft+ mountain passes.
Run it for:
Most of the run is done with 50% less oxygen than at sea level. Add in to that fluctuating temperatures from -12 to 40 degrees celsius, and you’ll get a good idea of what sort of brutality your body will be put through. The three climbs to Khardung La, the world’s highest motorable pass at 5,359m, will push your physical and mental endurance beyond almost any other sports race. Under 59% of competitiors complete the race; can you be one of them?
Runners up:
- The Grand Raid Reunion/Diagonale des Fous (translated as ‘Diagonal of Mad Men’): 100 miles at La Reunion Island, in the Indian Ocean, with 9,643m elevation
- Gobi March, 250km in the Gobi Desert of Mongolia
4. Australasia/Oceania: Ultra-Trail Australia (UTA)

The route:
- In the Blue Mountains National Park in New South Wales
- 100km/62.1 miles (there is a 50km option as well)
Run it for:
In a country that boasts some of the world’s most spectacular scenery and wildlife, the Blue Mountains National Park is the most beautiful region of the lot. The World Heritage Area makes for a stunning ultra marathon, steeped in aboriginal history. Not for the faint hearted, the course involves an elevation gain of 4,400m, but the sense of achievement upon completing this challenge is immense. It is a hugely popular ultra, with many participants signing up to do it again.
Runners up:
- Tarawera Ultra: 100 miles exploring the lakes, forests and waterfalls of New Zealand
- Kepler Challenge: 60km through Fiordland National Park, NZ.
5. Europe: Ultra-Trail du Mont-Blanc (UTMB)

The route:
- Following the route of the Tour du Mont Blanc in France, Italy, and Switzerland. Based in Chamonix, France.
- 171km/106 miles, single-stage race with a total elevation gain of 10,040m/32,940ft
Run it for:
This is one of the most challenging footraces in the world, especially in terms of elevation gained in such a short time, and is on many experienced ultra runners’ bucket lists. The winners of this race complete the course in around 20 hours, running through the night. Only about 60% of competitors complete the race in any given year, as the race includes mountainous climbs and demanding descents, but there are also stunning Alpine views throughout. Since it crosses between three countries, this could be one of the only ultras where you need your passport with you.
Runners up:
- Spartathlon, Greece: 153 miles/246km in under 36 hours from Athens to Sparta, in the footsteps of Pheidippides.
- Dragon’s Back Race, Wales: 315km in 6 days, with average daily climbing of 3,100m
6. North America: Western States Endurance Run

The route:
- Sierra Nevada Mountains, California. Starting in Squaw Valley and ending at Auburn’s Placer High School.
- 161km/100 miles single-stage event, with cumulative elevation gain of 18,090ft/5,500m
Run it for:
This is known as one of the world’s toughest single-stage endurance races, taking on the rugged ranges and canyons of California. The race is also famous for its mythology: it started in 1974, when a man’s horse went lame before a 24-hour race, so he ran it on foot instead (18 minutes inside the time limit!). Nowadays, runners compete for one of the legendary belt-buckles: bronze for finishing in under 30 hours, silver for finishing in under 24 hours.
Runners up:
- Badwater Ultra: 135 miles around Death Valley and the Inyo mountains, with temperatures up to 54 degrees celsius.
- Hardrock Endurance Run: 100 miles in 48 hours on Southern Colorado’s San Juan Range
7. South America: The Jungle Ultra

The route:
- In the Amazon Rainforest of Manu National Park, Peru from the Andes mountains to the Madre de Dios River
- 230kms in five stages with humidity above 77%
Run it for:
This is a chance to explore a relatively unspoilt area of the steaming jungle, taking in cloud forests, mountains, and valleys. There will be arduous undergrowth, deep mud and river crossings to navigate, heavy rain throughout the challenge, and you might even run under nightfall. This is a wild course, where you will have to be almost entirely self-sufficient, so it is a test of endurance in the most extreme conditions. Being surrounded by a variety of rare wildlife will make for an incredible experience though.
Runners up:
- Atacama Crossing, Chile: 250km in 7 days in the Atacama desert
- Half Marathon des Sables, Peru: 120km in 3 days through the Ica desert

As we are approaching the end of the year, now is the perfect time to start thinking about your 2025 running goals, and what you want to achieve over the next 12 months.
We know it can be hard to know how to set your running goals, so we have asked Jordan Foster, Head Coach at Coopah, the Run Coaching App to share her top tips.

I honestly love nothing more than sitting down at the end of December and writing a list of what I want to achieve the following year; whether that's running, professional or just general day to day life. But, for the purpose of this blog, let's stick to running.
And do you know the best thing about running goals: your goals are entirely your own.
- If you want to just start your running journey, amazing.
- If you’re chasing a personal best (PB), go for it.
- If you’re aiming to cross the finish line of your first marathon in one piece, incredible.
The exact goal itself doesn’t matter as much as the process of setting it, and building the plan to achieve it. So, here are some tips to help you create meaningful and achievable running goals for 2025.

Be Specific
Think about what really matters to you, as I said a goal doesn’t always need to be time based, but having a clear, specific goal is a great way to not only stay motivated, but also to ensure you are doing the right things to help you get there. For example a vague goal like “start running more” is a good start, but the magic really happens when you get specific and know exactly what you are aiming for;
- Want to aim for your first 5km? Awesome, set yourself a target date of when you want to achieve it to give you something to aim for.
- Running your first marathon? Brilliant, maybe the goal is to finish strong and soak in every moment.
- Just want to build confidence and consistency? Great, focus on nailing your training plan.
How Coopah Can Help: When setting up your training plan we will ask for your goal for your event, along with finding out more about your running history and experience. Which in turn will generate you a personalised training plan that is tailored specifically to your current fitness level and your overall goal. So you have peace of mind knowing that your plan is designed with your end goal in mind. Download the app and get started today.

Be Brave
Let’s be honest: big goals can feel scary. But does that mean we shouldn’t set them? Absolutely not.
Over the years, I have set myself many big goals in running. Some of these I have achieved, and some I have not. But does that mean I have failed? Personally, I don’t think so.
Because I still put myself out there, I still worked hard towards trying to achieve it and I showed up and tried my best. And that is really the most important thing.
So set those big goals. Be brave and push yourself. And remember, the best growth happens when we take on those big challenges that feel slightly out of reach.
How Coopah Can Help: Having the right support can make all the difference when setting those big goals, and with Coopah you have 24/7 access to our team of coaches who are on hand to help, support and advise you throughout your training plan. Whether you have a question about your plan, need that extra bit of motivation or just want to share how you are getting on, we are there for you every step of the way. Download the app and chat to your coach today.

Be Realistic
That said, whilst being brave is great, it’s also important to be honest with yourself and make sure those goals you are setting are realistic in the time frame you have;
- How far away is your event?
- How much time can you realistically commit to training each week?
- What’s your current fitness level?
For example if your dream is to run a marathon, but right now you are right at the start of your running journey, you may just need to take a step back and set yourself a smaller goal to achieve in the short term, whilst creating a long term plan to achieve this.
By setting yourself smaller, manageable goals this will also help to keep you motivated during your training as you will hopefully see progress a lot quicker, whilst knowing everything you are doing is getting you one step closer to achieving your ultimate goal.
For example your first goal could be to run your first 5km, then build up to 10km and so on.
Remember, progress in running takes time. It takes effort, hard work and commitment. We can’t always achieve everything we want to do at once, so having those long term goals and plan is a great way to keep you motivated to ensure you are always heading in the right direction.
How Coopah Can Help: With Coopah you can easily track your progress to see if you are on track to hitting your goals. Every workout will be tailored to your overall goal so you can see in real time if you are hitting your target. Download the app and start making progress from today.

Be Prepared
So here is your challenge for this week. Take some time to sit down, grab a notebook, or even the notes app on your phone, and think about your running goals. Not just the easy ones, but those big, bold, slightly scary goals too. Write them down.
Now, once you’ve got those goals in front of you, I want you to think about how you’re going to achieve them, and use the tips from this blog:
- Be Specific about what you want.
- Be Brave and aim high.
- Be Realistic about your current fitness and life commitments.
I promise you, just writing your goals down is a huge step forward. Once you’ve committed to them, you’re already on the journey. And remember, the journey itself is part of the fun.
You might hit your goal in 3 months, or 6 months, or it could be a long-term goal that takes a few years. Whatever the timeline, every time you lace up your shoes and head out the door, you’re one step closer.
So next time you’re on a run, remind yourself: every mile, every sweaty workout, every “I really don’t feel like this” moment is part of the process. Celebrate the little wins along the way, as they’re what make the big wins possible.

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.
