Summary
Brief summary (as posted)
Recreational UV exposure is associated with every form of skin cancer and individuals who engage in more physical activity have a higher prevalence of sunburn, a proximal biomarker of melanoma risk, perhaps explaining why melanoma is the only cancer with which physical activity is positively correlated. Mobile technology for tracking physical activity has become increasingly prevalent and Strava, an activity tracking app and social networking site for athletes, is one of the most popular of these technologies. This research will test the feasibility of delivering location-based, ecologically-valid sun safety advice to Strava users at times when they are predicted to be engaged in outdoor physical activity, by utilizing Strava's public open-source Applications Programming Interface.

- Intervention Group
- description
- Participants will be enrolled on a rolling basis and participate in SS for 4 weeks in the intervention condition. After pretesting, participants will receive sun protection messages from SS through emails/comments based on results from their activity data. All participants will complete posttest survey 4 weeks from randomization.

- Control Group
- description
- A small control group will be included to see if a no-treatment control condition is acceptable to users and estimate follow-up rates for planning a randomized trial. Participants will be enrolled on a rolling basis and will complete a pretest at randomization. All participants will complete a posttest survey 4 weeks from randomization.
