In Asturias the route was designed, executed and approved by the Federation of Mountain Sports, Climbing and Hiking of the Principality of Asturias (FEMPA) in 2000, crossing Asturias from north to south, from Gijón to Pajares on the occasion of the Eurorrando.
Subsequently, the FEMPA designed, executed and homologated the GR 100.1 Via de la Carisa. Much of this path runs along the layout used by the Roman general Carisius for the conquest of Asturias.
In 2013 the Silver Route Cooperation Network proposed to FEMPA to modify the layout to adapt it, as far as possible, to the historical route of the Asturica ad Legionem Augusta or Asturica Augusta and Legio VII with the transmontan lands of the north of the Iberian Peninsula: Lucus Augusti (near Lugo de Llanera) and Noega (Gijón) , through the Via de La Carisa and keep the number of the Grand Tour.
According to THE FEDME, FEMPA had no problem modifying the signature of both GR, becoming known as: GR 100 Ruta de la Vía de la Plata.
The itinerary enters Asturias through the heights of the Carisa between the municipalities of Aller Lena and runs through the central Asturian area until it flows into the Cantabrian Sea in Gijón.
