What is an Ultra Marathon? Learn about Ultra Running Here.

An ultramarathon is any footrace longer than the traditional 26.2 mile marathon distance, though typically they begin with a 50km distance. These “ultra” are capturing the fascination of both elite runners and amateur athletes worldwide. 

As participation grows exponentially each year, these superhuman tests of physical and mental endurance are becoming more than just a niche sport. 

This extensive guide will explore everything you need to know about the captivating world of ultrarunning.

The Rise of Ultra Marathons: More Than Just a Trend

In recent years, ultramarathons have exploded in popularity beyond the domain of hardcore running fanatics. While statistics on participation were historically scant, estimates suggest ultramarathon finishing rates in North America swelled from around 25,000 in 1998 to over 80,000 by 2011. 

Other regions from Europe to Asia have witnessed similar growth.

Several driving factors likely catalysed this upsurge. Internet resources have enhanced exposure and made ultras more accessible to everyday athletes. 

Improvements in sports science, training methodology, nutrition, and gear have also enabled more runners to tackle lengthy distances. And some speculate that amid increasingly busy modern lifestyles, ultramarathons provide purpose and fulfilment above and beyond regular marathons.

Whatever the ingredients, the result is clear – ultramarathons are firmly in the mainstream. Major events like the Western States 100 or Leadville 100 now draw thousands of registrants vying for limited lottery spots. 

While still a fraction of marathon participation, the ultrarunning movement shows no signs of slowing its explosive trajectory. These super-long races are more than just an ephemeral trend but rather reflect a fundamental desire to test the absolute limits of human endurance.

What Defines an Ultra Marathon?

First, let’s clearly establish what constitutes an ultramarathon. The prefix ‘ultra’ actually just means anything beyond, longer than, or exceeding expectations. So by definition, an ultramarathon is any footrace longer than the traditional marathon distance of 26.2 miles or 42.2 kilometres. 

There is no firm rule on exact cutoff distances or required terrain – simply anything on foot beyond the full marathon counts.

Some common ultramarathon race distances include:

• 50 kilometres (31 miles)
• 50 miles
• 100 kilometres (62 miles)
• 100 miles
• Time-based races (6 hours, 12 hours, 24 hours, etc)
• Multi Day stage races

So while the marathon has long been considered the pinnacle of running, ultramarathons take endurance to the outer limits. Distances range from slightly extended versions of a marathon to unfathomably long feats of hundreds of miles. Let’s explore the many variations of this extreme sport.

Common Ultramarathon Distances

As we’ve established, ultramarathons have one simple defining quality – they surpass 26.2 miles. But within this unlimited realm, some common race formats have emerged:

50K Ultramarathons

The 50K (50 kilometre) ultramarathon typically covers 31 miles. Essentially a longer version of the marathon, 50Ks represent the most common entry point for those new to ultrarunning. 

The extra 5 miles provides a moderately extended challenge without the intensity jump required by say a 100 miler. With aid stations and terrain akin to a marathon, the 50K lets runners explore beyond 26.2 miles in a relatively approachable experience.

50 Mile Ultramarathons

Stepping up to 50 miles understandably increases both physical and mental demands. Training, fueling, hydration, pace management, and gear choices become even more important at this distance. 

Likely requiring 10+ hours for most recreational runners to complete, 50 milers force deep fatigue management. But the highly rewarding feeling of covering such vast ground on foot makes 50 milers a popular choice.

100K Ultramarathons

Covering approximately 62 miles, the 100K distance equates to roughly 2.5 marathons back to back. Even for seasoned marathoners, it represents a giant leap requiring significant training adaptations. 

The duration alone (often 12+ hours) imposes massive physical stresses. Body and mind are pushed to unfamiliar extremes – a true voyager’s distance.

100 Mile Ultramarathons

The 100 mile (160 kilometre) ultramarathon stands as the Holy Grail distance that captures public imagination. Reaching triple digit mileage within a 24-hour cutoff seems barely feasible, yet thousands flock yearly to iconic races like the Western States 100. 

The relentless march of 100 miles epitomises the ultimate test of human endurance. Simply finishing a race of this magnitude becomes a life-changing achievement.

Timed Ultramarathons

Not all ultramarathons involve set distances. Timed events allow runners to cover as much ground as possible within a given timeframe. Common durations include 6 hours, 12 hours, 24 hours, 48 hours, and 6 days. 

Strategic pace management and fixed time eating become necessary to boost performance and avoid catastrophes like running out of gas prematurely. Timed ultras present an intriguing tactical challenge.

Stage Races

Stage races comprise repeated ultramarathon distances on consecutive days over an extended period. The best-known example is the Marathon des Sables spanning 6 days across the Sahara Desert. 

Each day presents a new start, not a continuation, with stages from 20 to 90 kilometres long. Recovery, pacing, and preparation between daily efforts become paramount in conquering these cumulative challenges.

Clearly, myriad race formats allow athletes to push their limits. We’ve only scratched the surface of the creative ultramarathon distances devised by race directors and boundary-pushing runners worldwide. 

Now let’s shift our gaze to the terrain upon which these races unfold.

The Terrain Factor: Where Do Ultramarathons Take Place?

If ultramarathon distances alone didn’t seem daunting enough, consider the types of terrain these events traverse. While occasional road ultramarathons do exist, most take place on the gnarliest trails imaginable – think remote mountain ridges, scorching deserts, or muddy forest tracks. 

The variability and difficulty of terrain poses another core challenge distinct from the length alone.

Popular ultramarathon terrain includes:

Mountains

Postcard mountain vistas often coincide with quad-burning ascents and daredevil cliffside descents on single track trails. Prominent mountain ultramarathons include Hardrock 100 in Colorado’s San Juan Mountains and Ultra-Trail du Mont-Blanc (UTMB) circling Mont Blanc on the French, Italian, and Swiss Alps. 

Expect huge elevation gains, technical footing, and changeable mountain weather along these visually stunning routes.

Deserts

Baking temperatures topping 100+ degrees Fahrenheit paired with sandy washes characterise iconic desert ultras like Badwater 135 through Death Valley and Marathon des Sables across the Sahara. Relentless heat, exposed sun, and shifting sand create untold challenges and dangers for desert ultrarunners.

Forests

Prepare to duck, dodge, and weave constantly along technical forest running paths. Tree roots, loose rocks, creek crossings, and abundant wildlife sightings define forest ultramarathons like the Barkley Marathons in Frozen Head State Park in Tennessee. 

Careful footing and navigation are key to speed through these lush backcountry routes.

Jungle

Exotic and humid rainforest terrain awaits at jungle ultramarathons across regions like the Amazon or Borneo. Constant moisture, technical routes, heat, humidity, and wildlife all collude to offer vastly different obstacles compared to other natural environments. The jungle’s raw, unpredictable nature adds exhilarating complexity.

Arctic

Frigid arctic conditions bring unique gear demands but incredible scenery at races like the 6633 Arctic Ultra traversing Canada’s Northwest Territories. Navigation through snow and thin ice combines with relentless chill and shortened winter daylight to create arguably the ultimate endurance test.

Clearly, ultramarathon landscape variety adds nearly limitless dimensions to the sport. Mastering a chosen terrain’s specific skill set and challenges may rival fitness itself in determining race day success. 

Nature’s raw power comes to life when traversing these backdrops under your own power. Next let’s examine the aid runners receive along their voyages.

Aid Stations: Your Trail Running Lifeline 

Given the extreme distances and terrain involved, aid stations become mandatory oases along ultramarathon routes. Positioned every few miles, these points offer supplies, nutrition, and moral support to provide a lifeline for competitors. 

Aid station arrangements differ across events based on logistics, but most offer these key provisions:

• Water, sports drinks, and soda – Staving off dehydration and replacing electrolytes are aid station basics. Fluids may come in cups, bottles, hydration bladders, or water stations for filling packs.
• Energy gels, bars, fruits – Quick carbohydrates to replenish energy and stoke onwards. Sweet or salty snack preferences vary from runner to runner.
• Sandwiches, chips, broth – More substantial savoury foods to refuel. The variety and hot food options expand at later aid stations as hunger grows.
• Gear and medical supplies – Anything forgotten or needed can often be found at aid stations. Bandages, blister supplies, flashlight batteries, extra gloves – you name it.
• Shelter and seating – Aid stations offer cover from the elements along with chairs or cots allowing precious moments of rest for runners to regroup.
• Encouragement and info – The volunteers passionately cheer on every runner, provide distance/time updates, and give course intel ahead.

Well-organised aid stations can make or break an ultramarathon experience. These oases literally keep runners alive in the wilderness and profoundly influence race outcomes.

The Role of Support Crews in Ultra Running

Many ultramarathons also permit or even require personal support crews. These small teams aid an individual runner at checkpoints by providing:

• Custom nutrition and hydration based on runner preferences
• Help replacing gear like shoes and clothing
• Medical assistance like blister care or massage
• Navigation updates including course intel
• Emotional support and motivation

Since runners are often sleep deprived and disconnected from their surroundings, this outside support proves invaluable. Experienced crews become masters at identifying runner needs and offering individualised care at aid stations. 

Top crews can massively boost runner performance and morale over such unfathomable distances.

Pacers: Guiding You Through the Finish Line

In addition to aid station volunteers and personal crews, many ultramarathons allow the use of pacers – people running along with participants over certain later sections of the race. Usually 1-2 pacers are permitted, joining at designated locations in the second half of the event.

Experienced pacers provide these helpful functions:

• Ensure navigation, preventing wrong turns on weary runners
• Continue motivation and mental reinforcement
• Help maintain target pace or speed up if needed
• Provide physical assistance with gear, nutrition, or medical issues
• Give needed human connection amid physical and mental isolation
• Share their own ultramarathon knowledge and tips

Effective pacers give an enormous boost to fatigued runners struggling to maintain focus and speed. Their pacing guidance and morale boosting can be race saving. Top crews deploy pacers strategically at crucial moments to maximise advantage.

The Physical Toll These Races Have on Ultra Runners

Now that we’ve surveyed common race constructs, let’s explore the experience of actually running these mind-boggling distances. The unrelenting physical impacts imposed by 30, 40 or 100+ consecutive miles cannot be overstated. Simply put, ultramarathons break bodies in ways you never imagined possible.

Common physical effects include:

Extreme Fatigue

Deep exhaustion from endless miles will penetrate muscle and bone. By later stages, the simplest movements require supreme effort. The fatigue becomes inexplicable to the uninitiated.

Gastrointestinal Distress

Nausea, vomiting, diarrhoea – upset stomachs plague most ultrarunners. The prolonged exercise coupled with rich fuel intake is a volatile mix. Finding what the stomach tolerates becomes crucial.

Joint and Muscle Damage

Eccentric muscle contractions and relentless pounding inevitably cause muscle trauma, inflammation, and acute pain. Knees and ankles often bear the worst abuse. Joint stability work is vital.

Lost Nails and Toenails

Nails turn black, blue and eventually detach entirely weeks later as pooled blood beneath causes nail bed separation. Gentler downhill running is advised to avoid this gruesome outcome.

Chafing and Blisters

Nonstop friction causes horrendous chafing of inner thighs, armpits, and feet. Taping and lube help back-of-pack hot spots. Blisters from moisture or friction often stop runners in their tracks.

Low Blood Sugar

Appetite diminishes over hours of running yet quick carbs are vital. Dropping blood sugar can cause debilitating nausea and dizziness. Forcing down calories and sugar is necessary.

Dehydration

Catastrophic water and salt depletion have life-threatening effects. Packs and planned electrolyte replenishment are essential, especially in heat. Signs like headache and cramping signal brewing issues.

Clearly the unrelenting stress of ultramarathons imposes severe consequences that must be strategically mitigated. But the next section will show how the mind sustains even greater damage.

The Psychological Aspect: What Does it Take to Train for an Ultra

While the bodily impacts of ultramarathons seem unfathomable, arguably even greater strains are inflicted upon the mind. The sheer timescale involved extends exponentially beyond normal conditions experienced by body and brain. Those who complete ultras often cite mental resilience and stubborn willpower over physical gifts.

Common psychological effects include:

Overwhelming Mental Fatigue

Staying alert and engaged becomes progressively more difficult as sleep deprivation sets in. The brain desperately craves rest, seeking any distraction. Tunnel vision and microsleeps signal declining function.

Deterioration of Focus

Runners struggle to maintain concentration and present awareness. Simple tasks require supreme effort. Pacers play a vital role in providing external focus and guidance.

Loss of Appetite

The mere thought of eating makes many runners nauseous. Yet avoiding fuel causes an energy crisis. Forcing down even small bites becomes an exhausting chore.

Mental Obsession Over Pain

Amplified by exhaustion, every ache and discomfort consumes runners’ minds. Thoughts spiral endlessly on pains rather than entertainment or distraction.

Emotional Roller Coasters

Euphoric highs at aid stations crash into lows and self-doubt between. Stretches of joy, tears, anger, stillness, and despair fluctuate randomly due to exhaustion and isolation.

Hallucinations and Delusions

Increasingly disoriented, runners may see, hear, and believe experiences completely detached from reality. Hallucinations grow more vivid and frequent through sleep deprivation.

The unrelenting mental decay explains why many runners describe ultramarathons as 90% mental work. Hour upon hour of mental wrestling awaits. Preparing this muscle may hold the key to finishing.

Hallucinations and Ultramarathons: A Strange Connection

We briefly mentioned the prevalence of hallucinations among ultrarunners. But this phenomenon perhaps warrants more attention given its strangeness yet frequent occurrence in races of 50+ miles. Reports of vivid hallucinations and delusions span the ultrarunning literature.

Causes include:

• Extreme sleep deprivation – Most cannot sleep during the race. Micro-naps increase dreamlike hallucinations.
• Metabolic imbalance – Low blood sugar/sodium and high caffeine/electrolyte drinks disrupt the brain.
• Social isolation – Lack of conversation and human connection affects cognition.
• Sensory deprivation – Unchanging terrain creates dissociation and vivid imaginary senses.
• Pain – Discomfort, exhaustion, and repetition trigger the subconscious and distort reality.

While deeply fatigued, runners commonly report seeing animals or people alongside them, hearing voices or music, and perceiving distortions of the environment. Hallucinations become more frequent and intense as the race continues, testing sanity. But most ultrarunners realise these are merely manifestations of the overwhelmed mind. They represent another quirky dimension of the ultramarathon experience.

Why Do People Run These High Mile Races?

Now you may be wondering – why voluntarily take on such extreme punishment? Who willingly endures hours of agony and mental decay for…’fun’? The motivations are complex, but boil down to deeply personal fulfilment:

Physical Challenge and Achievement

Simply finishing something so brutally difficult builds massive confidence and pride. Experiencing the body’s capabilities is incredibly empowering.

Mental Growth and Resiliency

Proving one’s mental fortitude and coping strategies creates new awareness. The lessons apply well beyond running to life’s toughest trials.

Community and Camaraderie

The supportive ultrarunning community bonds over defying perceived limitations together. Lifelong friendships form.

Exploration of Inner Self

The extreme conditions foster deep introspection and insight. Profound meaning and lessons often arise during the raw stripped down experience.

Escape and Adventure

Journeying through stunning natural settings Satisfies the soul and provides escape from modern life. It reconnects people with primal human persistence hunting roots.

Health and Wellness

While taxing, training cultivates fitness and healthy habits with a strong community. People feel vibrant and engaged with long-term goals.

The takeaway – ultramarathons fill a deep-seated need for exploration, meaning, and connection that enriches lives immensely. Any suffering pales next to the fulfilment felt upon crossing the finish line. Now let’s prepare you to tackle your first ultra!
