SunBeast: Evaluating UV Protective Behaviors and Education Interventions Among Ultrarunners

April 23, 2026 updated by: University of Michigan Rogel Cancer Center

SunBeast: Evaluating UV Protective Behaviors and Education Interventions Among Ultrarunners at the Western States Endurance Run

Participants will be randomly assigned to either the intervention or control group using concealed allocation. The intervention-comprising targeted educational materials and behavioral prompts-will be delivered over three months preceding race day.

All study participants will be required to complete the pre-race survey prior to the intervention. The intervention group will complete the SunBeast Educational module once and receive monthly reinforcement messages leading into race day. The SunBeast Educational Program module consists of a 30-minute live, interactive online discussion and infographics/videos on skin cancer, UV index awareness, sunscreen use, protective clothing, and timing of runs. The control group will receive a general wellness brochure via email. The general wellness brochure will contain UV protection information but will also have other general wellness topics.
