Here are some racing tips to keep in mind when approaching a big race. Take these for what they are, suggestions.
Be efficient. Remember to keep your form; head straight, jaw relaxed, shoulders down, arms swinging back and forth by your hips without crossing in front of your torso, good even stride, and quiet landing. [Easier said than done.]
Replenish during the race. Depending on the distance of the race, you might want to consider eating a snack. However, race day is not the day to start experimenting. Eat things that you have already tested during your training and have found that work well for you.
Look forward. Not just for your form, look forward toward your target or goal. Give yourself little goals to reach during the race. This will not only keep you motivated, but will help the race go by faster. Before you know it, you'll be sprinting toward the finish.
Pass with authority. Once you decide you want to pass someone, make the pass and don't look back or second guess yourself. The slower you pass someone, the higher the chances are that he are she will try to stay with you. Every person you pass COUNTS.
