Once you know which trails are which, they make more sense. The two 2.5k loops oddly finish interlined with each other, and I still don't know how you run a race that way other than having people finishing through the same chute as lapping, or something. That was the iciest part today.
Lots of elevation to be had, though.
You're right about confusion out of the arena -- I'm sure I did it backwards. At least there was no one else around. And the elevation, a good chance for you to make progress towards your target.
