Formigal is the anti-Arcalis. It is the kind of stage that usually is a recipe for a tempo climb and a last couple of kilometre shootout in modern cycling, and unless you access it from France via Pourtalet and turn it into a punchy finish on the end of a longer climb (along similar lines to the Châtel-Portes de Soleil stage in this year's Tour) there aren't really any selective climbs near enough to it to do much more than that with it, but it just seems to have an aura that creates racing, wheres Arcalis just has this negative aura that seems to dissuade anybody from trying anything when, on paper, it's a perfectly reasonable cat.1.
