For anyone who is racing in the near future, here are my two favorite paragraphs from the article (I recommend reading the entire article):
"Only you know what got you to the race and will get you to the finish line. Everyone has character strengths and experiences that they can capitalize on in challenging situations. First, have awareness of what your strengths are and secondly, use them. Embrace your competitiveness, your humor, your grit. Remember, it was your time, money, training, and planning that got you to the race, so own it. Enjoy the process and focus on doing you on race day!
Successful athletes know their goal so well that they can close their eyes and create a mental picture of it in their mind. The more vivid and clear your goal is, the more your brain and body know where to aim. Motivation increases when you know where you're are aiming your efforts. This means creating a picture in your mind, putting visual cues of your goal in your environment, or writing it out specifically and clearly in your training log. Then leading up to the race, you can recall your goal to help focus and direct all that energy so you're more excited and less freaked out."
