Using onsite trail interviews, this study evaluates physical activity patterns and trail use among new and habitually active exercisers. The authors determined that 23% of the trail users were new exercisers. New exercisers were more dependent on the trails as a primary outlet for physical activity than were habitually active exercisers. New exercisers traveled shorter distances to access the trails and rated convenience as a primary reason for using them. Both safety and terrain issues emerged as enablers for trail use, and unsafe conditions emerged as a concern among new exercisers.
