Every October runners from across the USA and around the world travel to the Bank of America Chicago Marathon.

Along the way 12,000 volunteers and hundreds of thousands of spectators offered their support and applause as runners accomplished something magnificent by fighting their way to the finish line on Columbus Drive.
