There is no time limit for completing a marathon. Sometimes people who are physically challenged in some way will take until after sunset to complete the race, just to prove to themselves that they can. The fastest time ever recorded for a marathon was just over 123 minutes at the 2011 Boston Marathon.
Yes. You have to be 18 or older on race day. There is no upper limit.
You can walk in most marathons, incl. the NYC Marathon, as long as you finish within the courses time limit. For the NYC Marathon this is 8.5 hours. Larger marathons usually start runners in "waves" based on your anticipated completion time. If you plan on walking, for safety reasons it's best to start your race with the last wave.
A good pace, not too fast though. Go out and practice, time yourself, work up to the two hour time limit. You can do it.
60 percent of the time they complete it everytime
You'll get your answer after the running of the Mount Lemmon Marathon. http://www.mountlemmonmarathon.com/
Never during a marathon. Your body does not have the ability to metabolize fats into energy during the time it takes to run a marathon.
