It's a time to reflect on the hard work that allowed you to be physically prepared for race day.
Race week is also a time to bottle up energy to use for race day. We always tell our athletes to save their best performance for race day and race week is no exception. Patience is a virtue.
Race week is extremely special because it signifies the end of a journey. There was once a time when you couldn't do the things that you can do now and that's because you had a timeline when you started training and you worked hard to get to where you are now. The deadline has come and you are ready.
Just like you wouldn't try to get in one last long workout on race week to boost fitness, it wouldn't be practical or healthy to manipulate the diet in order to change body composition on race week. But even if that mentality doesn't apply, wasting a lot of your race day energy on how you perceive you look (especially compared to others) is not beneficial to your race day performance and can potentially affect how you fuel and taper your body on race week (and perhaps even on race day).
For many athletes, comparing your body to other, lowers self-esteem. If you doubt your body, you doubt your performance and all that training was a waste of time, money and energy.
Love your body as it has gotten you to this amazing place called race week and in a matter of days, you get to perform with your amazing body.
You have prepared the best possible for your race and before you know it, you get to experience racing in your event, with your current level of fitness, with your one and only, awesome body.
