Sometimes when it starts to feel lousy, you have to remind yourself that you are doing yourself good (building endurance, strength, mental toughness, etc.). The unpleasantness is worth it in the long run. Well, as long as you let yourself recover properly from an effort where you push it and don't end up with an injury.

I've seen you, Seven, and you are in great shape. And you are a runner. The good thing about being a runner is that success is measured in the simple act of running and not giving up. Who cares if you can never run a 6 minute mile? You just do your best and celebrate the fact that you are going longer distances, staying injury free, and improving your form.

My husband is inspiring. He's a chunky 50 year old whose been running for years. He does not look like a runner, but he's completed several marathons and half--marathons. He's slow, his form is all his own, but he keeps getting out there and enjoying it. This morning, he ran in Rock Creek Park at sunrise and enjoyed every minute.
