This paper proposes an evaluation method for a virtual sporting environment, called the virtaul marathon system. The virtual marathon system is an application of our newly developed locomotion device. An aim of the virtual marathon system is to achieve the novel communication environment that can tranfer the bodily sensations of an athlete in the competition to the users. To evaluate the virtual marathon system, we focus on the versatile subjective impressions in the marathon race. We describe the design methodology for the evaluation indices, using such impressions. And we discuss the validity of our proposed indices from the experimental result of the assessment.
