Organiser's Description

This is an unsanctioned event. This means the event is not recognized, supported, or supervised by any official organization. There are no bibs, trackers, or placements. This run is for those looking to spice up a training run or looking for a reason to get the crew together. St. Louis River to River is a point-to-point 28(ish) mile route and with it being unsanctioned or a self-supported route, it comes with some logistical planning on the runners end. Unsanctioned Hybrid has provided an outline of where bathrooms and water may be available under "Event Information", but it will be subject to the STL River to River route on Strava. You are free to create your own or follow someone elses route. Just make sure your start/finish lines are the base of the Saint Louis Arch and the Lewis and Clark statue in Frontier Park, Saint Charles. Registered participants will receive a lapel pin to remember the journey on foot. Go after it solo, with a friend, or with a group; just make sure to enjoy your adventure without the course markers. Keep your head up, eyes open, and participate at your own risk.
