Frame running, previously known as RaceRunning, is an adaptive athletic discipline, primarily for people with severe coordination and balance impairments such as cerebral palsy and Multiple Sclerosis. Athletes use a three-wheeled running frame, with a saddle, body support and most notably, no pedals. Athletes run over distances similar to other track and road running disciplines; 100, 200, 400, 800 meters as well as 5 kilometers, 10 kilometers, half and full marathons. Like running more generally, frame running can be competitive, recreational, or for health and fitness.
