Yes, you have as much right to race as anyone. If you're willing to put out the effort, you belong in the race. Follow an expert's tip. To offset prerace anxiety associated with a first race, don't get caught up in what others are doing. Focus on what you have brought to the race-your preparation, training and focus.
Proper recovery is essential for a positive first-race experience.
Take it easy. Keep things low-key for a few days after your race. Stretch a little more than usual. Jog a few miles if you feel like it or take a day off. Some runners enjoy cross-training by cycling or swimming to keep their legs loose.
