What’s Included

Amazing Post Race Feast

This course is not only known for the killer hills, one single giant loop, amazing aid stations, and very likely high heat. But, is also known for the amazing post race party feel with plenty of pizza and local craft beer.

Custom Bibs

All runners will receive a custom bib with the elevation profile. This profile will allow you to see what’s ahead on the course during the race. The elevation profile is placed upside down so you can easily read it while the bib is pinned to your shorts or t-shirt.

Major Swag

All of STR events are filled with goodies, while we know the killer hills and post race party will make you want to sign up again, we celebrate your finish with major swag. All of Folsom Lake Ultra Trail 110K finishers will receive a wrap from Orange Mud, and a handcrafted wooded buckle.

Cupless Event

Each runner is responsible for bringing their own reusable cup or water bottle. Reusable cups are small, are no problem to carry along while running and will save thousands of cups from being trashed, and possibly blown away littering our beautiful trails. We will have some small collapsible water containers for sale at the event, or we recommend you purchase one in advance at your local running store or online at HydraPouch.
