Objective To investigate the occurrence of physiological, immunological and biochemical changes in adventure race. Methods Twenty‐five professional athletes, 15 men (age 31.4 ± 5.36 years) and 10 women (age 27.8 ± 5.18 years) traveled 460 km for 4 days long in an international edition of Ecomotion/Pro AR World . Blood and saliva samples were collected before (day 0) and after (day 4) the competition. Results There were risings of α‐amylase and cortisol levels in saliva after the race (p<0.05). The relative changing percentages of α‐amylase and cortisol were significantly higher in women than in men (p<0.05). There were less relative changing percentages of glucose and lactate levels in women than in men (p<0.05). After the competition leukocyte counts got higher compare to the beginning and among gender women got higher leukocyte counts than men (p<0.05). Conclusion Long‐lasting exercises with high intensity moments and little sleep, as adventure race, promoted an increased stress and changes in the immune system which can harm athletes' sports performance and health.
