It is better to prioritize shorter trail distances (e.g., 20km) while being perfectly prepared, rather than embarking on ultra-distance running without adequate preparation, at the risk of having a traumatic experience.

This advice is based on a pragmatic approach to training load management and injury prevention. Scientific literature in sports medicine, notably observational studies on ultra-trail runners (e.g., Knechtle et al.), confirms that a lack of specific preparation is the number one risk factor for DNF (Did Not Finish) and musculoskeletal complications. The notion of 'well-being' during exertion is correlated with an alignment between physical capacity and the imposed demand, which sports science validates under the concept of progressive training load. While the creator emphasizes the mental aspect ('burying one's head in the sand'), research primarily highlights that preparation reduces systemic physiological stress. There is no exaggeration here, as the statement aligns with the fundamental principles of sports periodization. The approach is consistent: prioritizing long-term enjoyment and health over unprepared performance.
