 Background: Inability to walk outdoors restricts full participation in physical activity and community living for older adults that can reduce health-related quality of life HRQL. Older adults report limited outdoor walking with only 8 achieving the Canadian recommendation for older adults of 150 minutes of moderate-to-vigorous MV intensity physical activity per week. Known barriers to walking outside include fear, physical disability due to chronic disease, the appropriateness of footwear and walking aids, the physical environment, weather and temperature. Group practice walking outdoors in locations with variable environmental challenges has the potential to improve physical ability, confidence, outdoor and overall physical activity and social participation. The extent to which it is safe and feasible to implement this intervention in people with varying degrees of physical ability, preferences for where to walk, neighbourhood walkability, and to measure outdoor walking activity, is unclear.
