Coaches recommend trying to maintain as steady a pace as possible when running a marathon. Some advise novice runners to start out slower than their average goal pace to save energy for the second half of the race (negative splits). As an example, the first five to eight miles (8–13 km) might be run at a pace 15–20 seconds per mile slower than the target pace for later.

Typically, there is a maximum allowed time of about six hours after which the marathon route is closed, although some larger marathons (such as Myrtle Beach, Marine Corps and Honolulu) keep the course open considerably longer (eight hours or more).
