Run 1:31:00 
shoes: Salomon SpeedCross 2 2011
Didn't have the speed, but felt OK on the hills, and had the agility, which this was sort of all about anyway.
The Cresheim Aqueduct has been rather sufficiently closed off from transit. Which is good, because I find it hard to believe that multiple parties did not fall off of that thing to their demise.
It is also unfortunate, because it was pretty awesome to run across that.
