Over the river and through the woods

I'm stalling.. I'm planning to run a 22 miler today and I'm waiting for it to warm up a bit. It's 15 degrees and I'd like it a little closer to 20. I'm planning to get dressed in a few minutes and then load up my gatorade and gu in my waist pack and hit the road. It will probably take me about 3 hours and 20 minutes. I'm running pretty slow on longer runs and think I might throw in a few hills. I'm heading over the river and through the woods.. literally. We have a series of dirt roads right across the river from our house and while I'm getting pretty tired of running on the same roads, I am very glad they are so convenient.
