Dreaming of Hills

I walked about 3 miles last night instead of speed training. It was less boring because another injured friend walked with me. But it's getting old. I miss running! I find myself craving a tough run. I start imagining a route with all the hills that I hate. I can see the hill infront of me so clearly and remember the feeling of glutes and calves engaging as I start the ascent. The feeling of my shoe gripping the asphalt and pushing it behind me. This has to be what it's like to quit crack.
