Ran the Assault on Sylvania Mountain 5k last night at a 9'48" pace. I could've done better, but I don't want to push it. I'll do faster before next week.
In the last quarter mile, there is a 400 - 500 ft elevation change. You have one hill, and then after you climb over the serpent's broken back, you get about 0.05 mile breather before you have to attack the head.
I sprinted up it last night, so I feel like I could've bettered my pace if I had sustained my starting pace a little longer. I was afraid I'd run out of juice. I normally take a different route so I skip the first hill on the way back, but I wanted to see what I could do.
After running this route for the past couple months, I don't think hills have any effect on me at all anymore.
