From the Roman Colosseum to the rings of the Olympic Games, circles have long symbolized the spirit of competition and served as a badge of honor. As we designed the logomark for this year’s Muscular Dystrophy Association Chicago Muscle Team event, it seemed only natural to evoke this classical trope. Now in its 15th year, this event brings professional athletes together to put their muscle behind a worthy cause: conquering the 43 neuromuscular diseases that affect more than one million Americans. 50,000feet is proud to support the MDA, which has helped generate more research on neuromuscular diseases than any other private sector organization in the world. www.50000feet.com/news
