Kaixo!
This is an amazing race that has only got better over the years. Everybody seems to compare it with a mountain stage of the tour de france for atmosphere.
What year did you do it? I went in 2003, 2004 and returned in somewhat worse shape this year.
There are a couple of decent campsites near Alsasua that do self-catering accommodation in log cabins too. Half an hour drive from Zegama though. Could dig out more information if you're interested.
