Roots, rocks and logs

I went trail running today to get ready for my 10K trail run next weekend. I dodged many a rock and root while traversing some of the narrower trails in our nearby Forest Park. I felt pretty good as I hurdled one large log at the beginning of my run, but on the way back, that same log seemed twice as big and I had to negotiate my weakened stride a bit.
Overall, I really enjoyed the trail. I hope to be able to explore more trails in my running shoes before next week.
Here is a look at the elevation profile of the trail I will be "racing" on:

I figure as long as I can get up that first hill, I'm golden. But can I run uphill, nonstop, with an elevation gain of 500 feet in less than one mile? That is the question...
