Some fatigue is normal, but you don't want to finish exhausted, otherwise you are training too hard. I know you're an Intermediate-I runner, worthy of respect, but don't be afraid to walk occasionally to break the pace. Rehearse everything you plan to do in the marathon itself, including what clothes to wear. The days are longer. Use these extra hours of daylight to get out before the sun rises too high.
Temperatures are cooler, the air cleaner and the scenery prettier in the hours around dawn.
If you are training through the winter, midday may be the best time for you to run. It will help get you to the starting line and, most important, get you to the finish line.
