Psychological Impact of an 80-km Ultra-Endurance Race (PSYTRAIL-80)

May 21, 2026 updated by: Centre Hospitalier Régional d'Orléans

A Study of the Psychological Impact of an 80-km Ultra-Endurance Event

Ultra-endurance races (ultra-marathons) take place under extreme environmental conditions, over long distances, involving prolonged physical activity and multiple psychological and physiological challenges.

These extreme conditions expose runners to a wide range of emotions-both pleasant and unpleasant-that can influence their performance, fatigue, and perception of exertion.

Emotional intelligence and emotional regulation appear to be key determinants of emotional trajectories and performance in these contexts. Previous research shows that high levels of emotional intelligence and adaptive emotional regulation strategies are associated with functional emotional trajectories and better performance, whereas maladaptive strategies are linked to dysfunctional emotional trajectories and reduced performance.

Furthermore, defense mechanisms constitute a complementary approach to emotional self-regulation. They can be adaptive or maladaptive and influence how runners cope with emotions and psychological stressors during competition.

Longitudinal studies conducted to date have primarily explored post-race emotional trajectories in relation to emotional intelligence, without examining the impact of defense mechanisms on emotional dynamics during the race. Furthermore, few studies have examined the mediating role of emotional intensity between emotional regulation and perceived performance, and even fewer have adopted an approach that integrates physiological indicators such as heart rate or heart rate variability.

Thus, this study lies at the intersection of sports psychology, emotion, and physiology, and aims to fill these gaps by exploring:

  1. the influence of defense mechanisms on emotional dynamics and physical and mental fatigue during an ultra-endurance race, and
  2. the mediating role of emotional intensity on the relationship between emotional regulation and perceived performance.

The objective of this study is to examine how certain psychological mechanisms used to cope with difficult situations influence the evolution of emotions experienced by participants during and after an 80-kilometer ultra-endurance race.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Defense mechanisms will be assessed before the race using the Defense Style Questionnaire - 26 (DSQ-26). Emotional intensity will be assessed before the race, during the race (at the 25-, 38-, 48-, and 56-kilometer marks), and at the finish line.
Time Frame: Before, during (kilometers 25, 38, 48, and 56), and at the finish line (80th kilometer) of the "Ecotrail de Paris Ile de France 80 kilometers" ultra-trail race taking place on March 21, 2026.
Defense Style Questionnaire - 26 (DSQ-26). Scale from 1 to 6, with 1 being "never" and 6 "always".

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Evaluation of physical and mental fatigue before, during and after the race
Time Frame: Before, during (kilometers 25, 38, 48, and 56), and at the finish line (80th kilometer) of the "Ecotrail de Paris Ile de France 80 kilometers" ultra-trail race taking place on March 21, 2026.
Physical and mental fatigue will be assessed before the race, during the race (at the 25-, 38-, 48-, and 56-kilometer marks), and at the finish line (80-kilometer mark) using a visual analog scale. Scale from 0 to 10 with 10 being the worst score.

Exploration of the relationships between emotional regulation strategies and runnners' perceived performance

Emotional regulation will be assessed before the race using the Cognitive Emotion Regulation Questionnaire (CERQ). Scale from 1 to 5 with 1 being "never" and 5 being "always".

Perceived performance will be measured using a performance satisfaction item during the race (kilometers 25, 38, 48, and 56) and at the finish line (80th kilometer).
