Last Day on Frances Route?

I'm in a place called Terradillos de los Templarios. Sahagun, which is a biggest town about 12km west of here. Since I've already done "this" Camino, which has about 350km left, I'm planning on catching a train or bus from Sahagun to Leon, then from Leon to Zamora so I can finish the Via de la Plata, which I abandoned for the the Portuguese coastal route last year. I think it's hard and hilly, with about 400km left to Santiago, but every step will be new. I think it's the only route that doesn't finish with the route of last years "60km day". Not sure if I've mentioned the 60km day but let me know if you want to hear all about it.
