One of my favorite tracks ever was at snowmass, 2007, as featured in the popular cycling movie Stars and Bars. It was pretty flat, and was 3 minutes of mowed grass, taped off. It was drift city. The bummer was, in the middle there was a right turn into a creek crossing, then you pedaled uphill out of the creek bed. This was followed by a 30 second flat fire road pedal.
What? A creek crossing in a race?
Yes, a creek crossing in a race. One of the stupidest features I've ever seen. There was an uphill out of this, and a speed-killing turn into it.
It made for some wonderful, close-up slow mo Clay Porter shots, though.
