. Blood glucose is the main source of energy during exercise, especially in endurance sports such as cycling, therefore, in this study, serum cortisol levels will be measured before and after being given treatment in the form of 30 km cycling training. The purpose of this study was to determine changes in serum cortisol levels after a 30 km cycling event in the cycling community in Makassar. The research method was quasi-experimental with a one group pre-test post-test design. Sample selection using the purposive sampling method by meeting the inclusion criteria in the form of active cyclists, cycling for more than one year, men aged 30-60 years, willing to have blood samples taken. Exclusive criteria include having a history of cardiovascular disease and a history of hypertension. A total of 30 respondents were collected at one time for an initial health check and blood sampling (pretest). A week later, a 30 km event was carried out. After the event was completed, the respondents were re-examined for vital signs and blood was taken later (posttest). The collected blood was centrifuged to obtain serum. Then the serum was examined using the ELISA method using a cortisol kit. The results showed a significant decrease in serum cortisol levels of -1.93 µg/dL from 13.33 µg/dL to 11.34 µg/dL (-14.19%) after traveling 30 km. In conclusion, there is a difference between pretest and posttest cortisol levels, so it is concluded that cycling 30 km can reduce cortisol levels in cyclists
