*The Rockin' Rockwoods 53K, 1/2 Marathon & 1/2 Marathon RUCK are the toughest trail events you will run in St. Louis, MO.
We guarantee it!
The terrain ranges from hard-packed dirt to lose, uneven rock and extremely hilly, technical trails.
This is a challenging course of steep grades and rolling hills. Runners will be treated to 95% singletrack with rocks, roots, and creek crossings that make for a fairly technical out-and-back run.
In addition, we are proud to be part of the 50K Mashup SLAM!
