Ultra running stretches beyond the marathon, featuring distances of 50k, 100k, 100 miles and even further. If you’re intrigued by the endurance, the strategy, and the sheer willpower required to conquer these events, you’ve come to the right place.

Whether you’re here to simply learn more about ultra running, a runner aiming to tackle your first ultra, or a seasoned ultrarunner looking to optimize your performance, this guide provides all the information you’ll need, including strategies to prepare, compete, and thrive in the world of ultra running, long term.

What is ultra running? Let’s start by answering the most obvious question.

Ultra running elevates the experience of running to an extreme level. Unlike a traditional marathon which covers a distance of 26.2 miles, or a half marathon with 13.1 miles, ultra running encompasses events that extend beyond the marathon distance, for those who just want more.

A 50 kilometer race is the best distance to target if you’re planning to start training for your first ultramarathon, as it’s really the “shortest” recognised ultramarathon distance and therefore the most accessible – it also happens to be my favorite ultra distance.

I say “shortest” but 50km is still a serious challenge, especially when you factor in all the elevation gain, technical terrain, eating (yes, a large part of the challenge is learning to eat enough during an ultra without the gut bombs), and running at elevation that you’ll likely experience during the race, or as I like to call it, the ‘journey’.

The most popular categories of ultra running races are 50k, 50 mile, and 100 mile distances, and the majority of ultramarathons will actually take place on the trails.

That’s me, taking a moment to admire the view at the halfway point along the Vertical Kilometer route in Chamonix. It’s something I love doing whenever we visit Chamonix in the summer and the perfect way to access some of the most beautiful trails long run days.

Renowned ultramarathon events such as the Ultra Tour Monte Rosa (UTMR) in Italy, Ultra Trail du Mont Blanc (UTMB) in Chamonix France, Western States 100 Endurance Run in Northern California, and Hardrock 100 in Colorado have carved out their distinct niches in the world of ultra running, showcasing some of the world’s most challenging and scenic trails.

The current world record for the longest distance ever run is held by Ashprihanal Pekka Aalto, who covered an awe-inspiring distance of 77 miles daily for 40 days in 2015 (a total distance of 3100 miles) – It’s one of the many astonishing facts about running.

The allure of ultra running, why would anyone want to run so far?

What draws individuals to the arduous world of ultra running? The allure of this wild and wonderful sport lies in:

  • Its unique combination of physical and mental challenges make it addictive when you realise it’s actually possible to complete such a huge challenge, as long as you commit to a smart training plan, and eat the right foods during your training runs and races.
  • Its ability to foster a deep connection between yourself and naturetrail and ultra running is so good for the soul.
  • The personal growth and accomplishment it inspires is one of the many benefits I get from trail running in general but ultrarunning is next level.
  • Its role in improving mental health and addiction rehabilitation has been seen time and time again. Runners find solace in swapping their previous addiction for bagging miles instead. It’s much healthier, confidence building, and provides ‘Ikigai‘, that’s ‘a sense of purpose’, or ‘a reason for living’ in Japanese – yes, they have a word for it because it’s so important to mental health.

If you’re still not 100% convinced, have a read of some of these ultra running books; they should provide all the inspiration you need to get into it.

The icons of ultra running

Now, let’s shift our focus to a couple of the luminaries of ultra running who have significantly contributed to the sport’s expansion and popularity, including:

  • Kilian Jornet
  • Courtney Dauwalter

These athletes have accomplished remarkable feats in the sport and continue to inspire upcoming runners but of course there are so many more which I can’t get into in this article as it would turn into an ultra in itself. I’m merely listing two of the greats to inspire you to go search out other runners.

Kilian Jornet

Hailing from Sabadell, Catalonia, Spain, Kilian Jornet is a distinguished professional in the fields of ultra running, skyrunning, trail running, and ski mountaineering.

Kilian Jornet has exhibited stellar performances in ultra running, with victories in prestigious ultramarathons such as the Ultra-Trail du Mont-Blanc, Grand Raid de la Réunion, Western States, and Hardrock under his belt. Furthermore, he holds the title of world champion in Skyrunning and Vertical KM, and is a European champion in Skyrunning, Ultra, and Vertical Kilometer events.

He has also set an incredible amount of Fastest Known Times (FKTs) for summiting Everest without supplemental oxygen or ropes, and also world records for ascending and descending famous mountain peaks around the world, including Mont Blanc, The Matterhorn, and Aconcagua to name a few.

Courtney Dauwalter

American ultrarunner Courtney Dauwalter is another force to reckon with in the ultra running world. She won the 2017 Moab 240-mile race in Utah outright, beating the second-place finisher (a male runner) by more than 10 hours. Her winning time was 2 days, 9 hours, and 59 minutes.

In 2023 she made history by becoming the first athlete to win three prestigious 100-mile races in the same year: the Western States 100, the Hardrock 100, and the Ultra-Trail du Mont-Blanc (UTMB).

Dauwalter set new women’s course records in both the Western States 100 and the Hardrock 100 in 2023, further cementing her status as one of the most elite ultramarathon runners​​ ever – and she does it all with a huge smile on her face! What a star!

Getting started with ultra running and choosing the right training schedule

If the stories and achievements of these ultra running icons have sparked your interest in the sport, understanding the right way to embark on this journey is essential both for staying motivated and injury free, long term.

Now for some important aspects such as laying a solid foundation, choosing the right race for your first event, and the importance of investing in the appropriate gear and nutrition.

Building a solid foundation

Building a solid foundation for ultra running involves gradually increasing your mileage, incorporating strength training, focusing on proper running form, and taking particular note in recognising how well your body is recovering during training blocks, from running longer distances.

For more information on how to increase your mileage the smart way, and training for your first 50km ultra marathon, download our FREE 50K Training Plan, and follow my advice in the accompanying post which is full of insightful, and useful information.

Strength training, and training runs like hill repeats, intervals and tempo runs are all crucial as they enhance stability, increase speed, VO2 Max, and also running economy.

Lastly, practicing proper running form is essential to prevent injuries and ensure efficient running.

Selecting the right race

Choosing the right race is crucial for a positive ultra running experience. Factors such as the race distance, terrain, elevation gain, altitude, time of the year, number of participants, and location should be considered when selecting an ultra running race.

The terrain and altitude of an ultra running race will significantly impact the difficulty level, performance, and overall experience of your race. It’s crucial to select a race with terrain that aligns with your training and preparation to ensure success and enjoyment.

Furthermore, if you can’t simulate certain race route conditions in training (via local hills, or treadmill workouts), choose a location that aligns with your training conditions and terrain preferences to ensure adequate preparation for the race.

More about selecting your race can be found in my 50K Training plan and race guide.

Essential gear and nutrition

Investing in the right gear and nutrition is equally important for any ultra runner. Here are some essential items to consider:

There’s other very helpful, but not essential running gear to consider too, including:

And don’t forget to check your chosen race’s website in case there is mandatory gear which can include items like:

  • headlamp for visibility.
  • crampons for snow and ice.
  • extra water for extra hot conditions or races with sparse aid stations.
  • Waterproof jacket and waterproof trousers in case there’s inclement weather in the mountains.
  • Emergency whistle for getting attention incase of an emergency in the mountains.
