What’s Included

Major Swag

All of STR events are filled with goodies and custom bibs, while we know the killer hills and post race party with plenty of food will make you want to sign up again, we celebrate your finish with major swag. Each STR race has a little different swag because we know nobody needs 14 beer pints, or 12 tshirts.

Aid Stations

All of STR events are full of great aid station with the best available volunteers. The volunteers will help you fill up your bottles and quickly move toward the finish line. Depending on your event distance, our aid stations may include soda, boiled potatoes, candy, gels, electrolyte, salt tablets, and much more.

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.

Early packet pick up for all distances will occur at Auburn Running Company from 1-5pm. We will not give out Sunday's bibs during Saturday's race. If you cannot attend the early PPU, you can pick up your packet starting 1hr before your race, Saturday or Sunday.
