Reality: Lots of new runners have anxiety about their first racing experience. They have questions such as, "When should I eat?" "What is the starting line like?" "Could I get lost?" Reading about race day preparation is definitely helpful, but you may feel more comfortable if you attend a race before you actually run one.
Go watch a race or offer to volunteer so you can experience the race atmosphere and get a better idea of what to expect. You can also talk to friends and family members who have done races and ask them for tips and advice. Or, better yet, ask a friend who has run races in the past to "adopt" you for a race and show you where to go and what to do at the race. Most runners would be excited to introduce a new runner to road racing.
