The racing solution: If you think you're going to run faster than a majority of the field, get closer to the front. If you're a slower runner or walker, go toward the back. Many races have posted pace signs for minutes-per-mile. Bigger races have assigned corrals, based on your previous race times or your estimated finish time. Try to start near your estimated pace. If there aren't any pace signs or assigned corrals, ask the people around you what pace they'll be running, so you'll know if you're in the right spot.
