All three races (5K, Half Marathon, and Marathon) start together at 8am.
It is OK to change to a shorter distance race if you are having problems.
Just be sure to tell the workers in the finish chute that you changed to the 5K (for example). This is because the numbers are colored coded for each distance. We will need to make the adjustment for results purposes. However, don't let this be a crutch for you. Go for your goal distance, if possible. You may want to come run our Mayor's Cup 5K this Saturday, in Biloxi, before attempting a half marathon for your first race.
