A friend ran with me the first 10min and took some pictures and a video on the downhill. And we had water and gels stored at halfway. But I didn't use that. So I don't know if you would still consider it unsupported!? Anyway, I had a great day on the mountain. And good wine and food with my Canarian friend Victor afterward.
