Studies focusing on the territorial impact of outdoor activities rarely take into account the use of digital tools, such as digital mobile devices and applications. However, these digital tools can serve as sustainable outdoor infrastructure. While digital technology is not universally embraced by trail runners today, consumer studies confirm a growing usage of digital equipment. To provide a concrete example of how digital tools are used and their potential, our study aimed to understand the patterns of digital use among trail runners in France. Through an online questionnaire study (n = 699), we found four main logics of digital use: (1) playful visit, (2) tourist discovery, (3) performance analysis, and (4) social use. Among all forms of use, the most commonly mentioned applications used by respondents during their trail runs were Strava, Garmin, and Suunto. Overall, trail runners demonstrated a high proficiency in digital use, with 95% reporting the use of these applications.
