Marty entered a cross country skiing marathon, sponsored by Stowe Hills Resort (Resort). Resort advertised the marathon as being a 10-mile ski course on cleared, groomed trails through a wooded area. During the marathon, Marty fell when he skied over a relatively small tree limb on the trail and broke his leg.
