I think that most people's biggest obstacle on race day will be mental rather than physical. Expect to have doubts and fears, worries and unanswered questions. Expect that if you have never run it before, you cannot know how far 26.2 miles really is. Expect that you may have thoughts - even if they are not serious - of quitting. But also expect that you can overcome all of these feelings and finish strong.
