From the Sea to the highest peak of the Iberian Peninsula and back. Start and finish at Playa Poniente. The first 55km are paved then the route becomes a gravel road until 1km from the summit which has to be hiked.

The route can be a free route as long as you start and end at the sea then reach the summit.

Make sure to get water at Capileira as from there on there isn't much available apart from a lake near the summit (slight detour)

The Jedediah Smith Memorial Trail (or American River Bike Trail) is a paved multi-use pathway that runs between the confluence of the Sacramento River with the American River, just north of downtown Sacramento, California, and Beal's Point at Folsom Lake, north of Folsom.

The trail is 32 miles (51 km) long, and is used as a major recreational destination, as well as a commuter artery for cyclists. The trail is considered one of the longest paved purpose-built bike trails in the US. The trail was recognized as a national trail in 1974.
