This applies to a race, to a training run or just about anything you do. Just finish Baby!
Many times in my running career (yeah, I know that sounds weird but...) I have simply just wanted to quit, to just stop and go home. The mental battle is toughest thing about endurance sports in my opinion. If I can get those voices out of my head that tell me I am tired or that it is too hot, then I win! It is easier said than done.
People still ask me about Ironman and how hard it was. I used to say that it was the toughest day of my life, but now I answer them differently. Now my answer is this, that was the longest day ever. The reason it was so long was that it was a lonely day. I had a lot of time inside my own head. A lot of thoughts bouncing around (although now, I do not remember half of them). During an Ironman, you are thinking about the journey to the starting line, you are simply thinking about finishing. You are thinking about getting off that bike and how good it will feel to walk, then you are thinking about finishing that run. I do not remember a time thinking about the journey... until well after it was completed.
On Saturday, my wife and I lead a running group. As I was running with a guy, he said something about how running was a journey, which I do agree on 100%, but I also know that sometimes, you just have to finish. It's about getting through when you aren't sure if you can or if you even want to anymore.
You still have to finish to continue the journey!
Sorry about the song, but I love this video
