Come join us to explore a 400 KM route from Seattle to Tacoma and out into the Cascade Foothills.

To honor Tacoma's Frank Herbert and his sci-fi masterpiece Dune, we will visit the new Dune Peninsula Park built in Tacoma at the site of a former smelter (See Why did we name it Dune Peninsula?). You'll learn that as a teenager, Frank had a randonneur streak in him. We'd like to think he would approve of our human powered challenge through the region. We'll ride through urban/suburban/industrial areas then head into the less impacted but still threatened Cascade foothills. In the quite moments, you can ponder our impacts on the planet - which is one of the themes in Dune as Frank Herbert was heavily influenced by the smelter and environmental destruction of Puget Sound he observed as a child. The route will let you experience the ‘pleasures’ of the major planetary forces that shape our region: Hills formed by ice age glaciers 1 mile thick; 200+ ft high lahar flows from Mt. Rainier; and shoreline hills carved by water erosion from the never-ending rain.
I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me.
— Frank Herbert, "Dune"
