Quivering Quads History

In 1994, Fleet Feet Sports hosted the inaugural Quivering Quads Trail Runs within the boundaries of beautiful Cuivre River State Park.  The unique event incorporated race distances of 10 kilometers, 13.1 miles, 50 kilometers and 50 miles. 175 runners entered the inaugural event, which immediately became a fixture on the St. Louis area’s running calendar.  By 1998, QQ was the largest trail run in Missouri and an event of some national prominence.  The race was regularly featured in Ultrarunning Magazine and earned mention in Kirk Johnson’s 2001 book To the Edge, which documented the world of ultramarathoning.  The race went into hiatus after 2003’s 10th annual event so that Fleet Feet could attend to the growth of their Lewis & Clark Marathon and Half Marathon, which has now become Rock ‘n’ Roll St. Louis.  In 2010, QQ returned as the Quivering Quads Trail Half Marathon.
