We like to run trails

Wildcat River Runners are a running club in St Louis. We love running trails and hanging out afterward with fun folks. We are excited to partner with Pere Marquette State Park and Go! St Louis to put on the first annual Piasa Trail Races!

The inaugural Piasa Trail Races will be held on May 16th 2026 at Pere Marquette State Park, just outside of Grafton IL, one hour from Saint Louis Missouri.

We will have 3 distances: 12.5k, 25k and 50k.
