The phrase “it’s 100 per cent mental” is tossed around like a mantra in ultrarunning, suggesting that mental grit alone is what gets runners through challenging endurance races. While mental resilience is undeniably important, claiming that finishing is all in the mind oversimplifies the intense physical toll that these long-distance races demand. This mindset is not only misleading—it’s potentially dangerous. Here’s why.
Most of us have lined up for a race, of any distance, knowing our training was less than ideal and willing to risk a less-than-perfect performance. But believing that mental toughness alone can make up for a lack of preparation is risky, particularly in long races (often on isolated courses) placing unrealistic expectations on our mental capacity and ignoring the very real need for physical readiness.
Mental strength has limits
First, let’s be clear: no amount of mental grit can make up for a lack of training in ultrarunning. With distances ranging from 50K to over 200 miles, on mountainous, often technical terrain, the body needs conditioning to handle the intense demands. Without proper training, runners risk serious injury and even long-term damage.
After my first ultra, I learned a lot about my body’s capacity—and my own mental resilience. Realizing that I could go the distance gave me the confidence to tackle future races, knowing I had reserves of strength I hadn’t tapped into before. But that mental boost only went so far; my body still had to be physically prepared for each race. Mental resilience helps you push through tough moments, but there’s no substitute for the endurance, strength and injury prevention that come from dedicated training. Both body and mind are essential to finishing safely and successfully.
Physical preparation isn’t just about finishing—it’s about finishing safely. For some athletes, the financial investment alone in signing up for some races can lead unprepared runners to attempt an endurance race they are woefully unprepared for. Approaching an ultra thinking it’s “all mental” can lead runners to neglect training, setting themselves up for heartbreak or, worse, risking their health and the safety of others.

The risks of overemphasizing mentality
The “100 per cent mental” mindset can lead some runners to dangerous overexertion. By treating pain or fatigue as mere mental hurdles, they risk ignoring their body’s signals, which can lead to dehydration, heatstroke or serious injury. Pushing through rather than listening can have consequences beyond one race, with runners risking long-term injuries or even life-threatening situations.
Downplaying the physical demands of ultrarunning can also set unrealistic expectations, especially for newcomers. When runners believe they lack “mental toughness” due to physical struggles, they may feel discouraged—when the real issue may simply be a need for more conditioning. Race directors often have medics and rescue teams on standby for emergencies, as even experienced runners sometimes require aid or removal from the course. When inexperienced athletes put themselves at risk by over-relying on mental toughness, they may need these resources, impacting everyone involved.
Balancing mental and physical strengths
A successful ultra is about harmonizing both mental and physical strengths. Yes, runners need to train their minds to cope with doubt, discomfort and long hours on the trail. But they also need a strong, prepared body to carry them over technical terrain, up mountains and across long, seemingly endless stretches of trail. Effective training integrates physical endurance, muscle strength and strategic recovery—all components that mental strength alone cannot achieve.
Training for an ultra needs to emphasize a well-rounded approach, acknowledging the importance of both mental and physical endurance. This mindset not only helps runners perform better but also keeps them safe, as they’re more likely to listen to their bodies and make smart decisions in races.
