We developed a system for real-time athlete surveying and monitoring with emphasis on outdoor and endurance sports. The goal of our work is to pro-vide a lightweight, non-hindering and highly mobile application that is ca-pable of getting real-time information from an athlete about the physiologi-cal state and the prevailing workout situation, also focusing on its subjective perception. To provide this system, we implemented a software solution tailored to the task of online surveying and data recording on a standard mobile phone. In order to prove the usability of our design, it was used in a one hour running study with 84 participants. Self-rated information about the psychological state of the athletes as well as speed and GPS position information was col-lected specifically for this evaluation. We visualized the collected data in a combined way, integrating the speed and subjective state information in a joint representation together with terrain data and maps. The system proved to be highly reliable in practical use. Moreover, the majority of the study participants stated that the additional equipment was not hindering to their sports activity.
