I quite liked the couch detour. Perhaps it wasn't fun to watch, but it certainly was hard to do - exactly the opposite of things like bunjee jumping or helicopter rides, and I can definitely imagine teams like Ron and Chris or Mel and Mike struggle a lot carrying those couches across Vienna, especially in the snow. The chimneys were disappointing though.
Is it just me or this race is more physical than any recent one we've had? Except for the first leg there have been pretty tiring tasks all the time.
