The 100 Mile Challenge

James MacKinnon and Alisa Smith revolutionized the concept of the 100-mile diet. This method of eating relies solely on consuming those foods that are grown or produced within a 100-mile radius of one's own home. They place a challenge on the residents of Mission, British Columbia, Canada, a small town located in the Fraser Valley just east of Vancouver: live on the 100-mile diet for 100 days.
