Glen Redpath is a video and performance artist whose work often centres around his parallel interest in running. These include his 1998 performance project One Summer, in which he ran 10 marathon races, one in each province of Canada, between May and October, and Redpath:999-6773, an interactive gallery installation in which he ran the streets of San Francisco during gallery hours as visitors to the installation held conversations with him via cellular phone. Redpath uses movement and exertion as a measuring device to locate himself in relation to the surrounding environment and community.
