Think St. Louis, MO trails are flat?

Cute - Think again.

People picture crushed gravel and the rails-to-trails and sure, we've got plenty of those. But that's only half the story.

💥 Come run Rockin' Rockwoods, where we trade smooth paths for rocks, roots, climbs, and real grit.

Add in the classic Midwest heat and humidity, and you've got a challenge worthy of anyone who thinks they're tough enough.

💥 Come meet the other side of STL trail running - technical terrain and punchy hills that make Rockin' Rockwoods live up to its name.

~ Lace up and see if you can rock it ~
