I was looking at the calendar for the skyrunner series http://www.buffskyrunner.com and I see the first race is in Berga, Catalonia, only an hour or so from Barcelona or Girona Airports.
Has anyone any experience of these races, e.g terrain or distance, as I wouldn't mind giving this one a whirl.
Heard somewhere they are quite simialr to Sierre-Zinal.
