Clarksville resident Tatyana McFadden (Atholton), a 15-time world champion and four-time Paralympic gold medalist, will defend her course record at the 41st Chicago Marathon , organizers of the Oct. 7 event announced Tuesday. Four-time Paralympian Marcel Hug of Switzerland will be among those challenging McFadden in the elite wheelchair field that includes 22 Paralympians from 10 countries. They will return to Chicago on October 7 to vie for the Chicago Marathon crown. "Tatyana McFadden and Marcel Hug have become legends in the sport of professional wheelchair racing, and we are excited to welcome both of them back to Chicago for another run at a championship title," said Chicago Marathon Executive Race Director Carey Pinkowski. "It has been incredible to watch the growth of the sport over the last decade, and to see new athletes joining the front of the pack. We have a very competitive field this year." McFadden, a 17-time Paralympic medalist (including seven gold medals) and the Bank of America Chicago Marathon course record-holder (1:39:17), made history from 2013 through 2016 as the only female athlete to win four AbbottWMM races in one year: London, Boston, Chicago and New York. She closed out her 2016 season as the 2016-17 AbbottWMM Series X champion, and as the most accomplished champion in Chicago Marathon history. She returns to Chicago to attempt to capture her eighth consecutive Chicago Marathon title. She started her 2018 season with a second-place finish in Tokyo, a win in Boston and a second-place finish in London.
