You'll be hard-pressed to find someone who knows more about biking infrastructure in the United States than Stephen Clark. The longtime bicycle advocate has a deep résumé:
• Founder of Minnesota Coalition of Bicyclists (now Bicycle Alliance of Minnesota) more than three decades ago.
• First bike coordinator for the city of Boulder, Colo.
• Program manager for Transit for Livable Communities. He helped implement the federally supported Nonmotorized Transportation Pilot Program in Minneapolis, one of four cities to receive $25 million to demonstrate how walking and biking infrastructure can increase the activities in its city.
• Helped plan much of Wisconsin's Ice Age Trail, which was established in 1980.
• Served as the president of the League of American Bicyclists.
Splitting his time between Minneapolis and his farm in Cushing, Wis., north of St. Croix Falls, Clark, 58, is now the bicycle-friendly community program specialist for the League of American Bicyclists. He visits nearly 80 cities for the nonprofit each year to help communities become more bikeable and walkable.
Clark is someone who practices what he preaches. Traveling extensively for his job, he makes the 75-mile ride from his farm to Minneapolis-St. Paul International Airport via a foldable bike that fits into a case, that doubles as a bike trailer for his luggage. In the winter, he rides 100 miles to the American Birkebeiner in Cable, Wis., with a homemade bicycle ski rack. After racing the ski marathon, he packs up his skinny skis and pedals home.
