I still have bad runs and magical ones, I still roll out of bed with sore legs, arms, abs, and other muscles I scarcely knew existed (I love those days by the way)! I still have days where the couch sounds like a solid alternative to training and days where I can't wait to hit the weights, pavement, or the trail... but I embrace all of it as being part of the deal, part of the relationship I have with the training and I wouldn't change a thing.
What I ultimately realized is that I'm not running to get anywhere. I'm right where I want to be. The irony is, in order for me to get here, I had to run.
