The Westweg (Westvariante) goes from Pforzheim - Basel and crosses the hole Blackforest from North to South. Its the oldest long-distance hiking trail in the Black Forest and was founded in 1900. On the Trail you see the highest Mountains in the Black Forest and all in all its a trail to be recon with. The normal number of Dayhikes is about 12, but its still runnable all at once.

From https://en.wikipedia.org/wiki/Westweg:

The Deschutes River Railbed Trail is one of nine official Rails-to-Trails in Oregon, and follows the old Des Chutes Railroad line for 23.1 miles from Deschutes River State Park to Macks Canyon Campground.  The Deschutes is the sixth largest river in Oregon, and much of this section of the Lower Deschutes is designated a Wild & Scenic River, and a favorite with river rafters and kayakers.

Two loops adding up to ~10 miles in Hawn State Park.  The terrain is mixed; it follows a lot of creeks at the lower elevations with a lot of mud. There are a lot of rocky sections, but there is a ton of nice, runnable trail all throughout.
