Introduction
Excessive sun exposure and sunburns are the main preventable causes of skin cancer. The growing popularity of outdoor sports in developed countries has motivated the objective of this work to study the risk of photoexposure and the skin cancer prevention needs of athletes in an extreme race and evaluate an intervention targeted at this population.
Methods
An observational study was conducted during the XXIII edition of the 101 km de Ronda race, which consisted of trail running and mountain biking categories. Environmental and personal dosimetry, monitoring of meteorological conditions, evaluation of the athletes' photoprotection and skin examination habits, a dermatological checkup, and a satisfaction questionnaire were performed.
Results
The ultra‐endurance race was carried out under adverse conditions (maximum ultraviolet index (UVI) = 9.2, temperatures above 30°C, and relative humidity >35%). The mean effective erythema dose received by race athletes (n = 11) was 2959.2 ± 404.2 J/m2, equivalent to 29.6 standard erythema doses (SED). The CHACES questionnaire (n = 1145) showed a sunburn rate of 58% and poor protective habits: 62.9% of athletes do not usually use sunscreen and 67.2% do not self‐examine their skin. Actinic keratoses (4.7%) and suspicious skin cancer lesions (4.2%) were found in dermatologic screening exams (n = 170). On the satisfaction questionnaire (n = 111), this intervention was rated as excellent (95.5%).
Conclusion
This research highlights the extreme risk of photoexposure that athletes are subjected to during ultra‐endurance competitions. In the same way, it shows the need to carry out interventions aimed at the acquisition of healthy photoprotection habits and skin surveillance in this target group.
