More Butterflies

As if to validate Matt Ogdens classic course setting last weekend, the World Cup in Spain has a great little butterfly loop in the middle of a very long tough course. In this terrain you want to stay as straight as possible while wriggling through the contours. I'm not sure what their rough open is like, I imagine pretty rough, so overlay this with the scattered tree hash and you are looking at some potentially sapping terrain.

Competitors clearly must deal with more than the butterflies in their stomachs before the race....
