DATE/TIME | Sunday, March 8th, 2020

  • 50K | the first wave starts at 8:00 am
  • 13.1M | the first wave starts at 9:00 am

Cuivre River State Park is located in Troy, Missouri.  Runners are sent onto the race course in waves of 25 that have been seeded according to their predicted pace for a road half marathon. 

This year’s event will feature a completely new half marathon course and both courses will feature incredible bluff views. Along the course, runners can expect wide fireman roads, narrow single track trails, rolling hills, steep climbs (but not too many), and numerous creek crossings through the bottomland forest of Big Sugar Creek. Participants should also expect to experience your average midwest rocks, roots, mud, along with some spectacular wildlife.   The striking views along the course will remind you of the famous Missouri Ozarks.  The course offers new challenges for every level while enjoying the amazing scenery. 

Participants of the 50K will complete two loops.  Loop #1 will be ~17.9 miles, and loop #2 will be the half marathon course of 13.1 miles.  Limited course support will be available during loop #1, and 50K participants should plan to sustain themselves during the first loop. Please reference cutoff times below. 

Dogs are not permitted on the course or in the race.

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 a 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 became Rock ‘n’ Roll St. Louis.  In 2010, QQ returned as the Quivering Quads Trail Half Marathon.
