We ended up arriving at about 4.20 pm, just missing the train and had to catch the train to Calahorra and a bus from Calahorra to Logrono.
But it turned out that it wasn't so bad after all, considering what other horror might have befallen us.
On the way to Alcanadre, we had to climb up a small mountain and when we reached the top, we saw this huge black cloud hovering over the horizon. It was about another two hours to the village and we hadn't seen signposts for the last six or seven kilometers, so thought we were lost.
Just when we were about to give up, we saw a beautiful yellow arrow on an abandoned barn marking the camino. (The Camino de Santiago is pretty well signposted and it's hard to get lost but we were doing this stage in reverse, which is a lot more complicated that it sounds.)

I'm not sure if anyone was caught in the storm but I suppose it would've been quite uncomfortable to have hailstones the size of cricket balls pelting at your head.
