Location and Course | 2017 Course Map - updated map coming soon
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 10K.
The 2018 event features an updated 8.14-mile course that incorporates completely different trails from the original QQ and will take runners through some of the most picturesque areas of the park. The course will begin and finish near race headquarters at the beautiful stone lakeside pavilion. Heading out on the course in waves of 25, participants can expect rolling dirt hills, mixed with rocky patches, great scenic views from all angles around the lake and open fields with tall grass, before heading back into the woods. The course offers new challenges for every level; competitive runners can let loose and move into a flow around twists and turns without having to worry about difficult climbs. Novice runners will get a taste of a semi-fast course while enjoying awesome scenery. Beginners can enjoy striking views along the entire course that will remind you of the Ozarks, with some challenging footing and questions along the way to keep you on your toes!
To avoid overcrowding the trail, registration is limited to the first 500 entrants. Entry fees include a $3 fee charged by the Missouri Department of Natural Resources.
Participants can choose between a custom BOCO backpack or a vintage thermal long sleeve shirt. Want both items? Purchase the custom QQII backpack for the discount rate of $16 thru 8/26. After 8/26, the backpack will increase to $20. (regularly $35).
Finisher Medals & Awards
All finishers will receive a custom finisher medal. Awards will be awarded to the top three overall finishers and the top three in ten year age groups.

QQ was endorsed in 2014 by Outside Magazine, which named it one of the six best Outside running races. We're confident QQII will live up to QQ's great reputation.
History of Quivering Quads
In 1994, Fleet Feet Sports hosted the inaugural Quivering Quads Trail Runs along the beautiful single track trails of 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. In the late 90s, 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 Fleet Feet could attend to the growth of their Lewis & Clark Marathon and Half Marathon, which has now become Rock ‘n’ Roll St. Louis, and the Race Directors could attend to the growth of their kids. In 2010, QQ returned as the Quivering Quads Trail Half Marathon. QQ continues to take place every March.
