Albert Bennett, an amateur cyclist, participated in a bicycle race conducted by the United States Cycling Federation. During the race, Bennett was hit by an automobile. He claims that employees of the Federation improperly allowed the car onto the course. The Federation claims that it cannot be held liable to Bennett because Bennett signed a release exculpating the Federation from responsibility for any personal injury resulting from his participation in the race. Is the exculpatory clause effective?
