wonderful a sunless running

I've been searching for some marathon tips. Here's some inspiration from the Bangkok Marathon website (FAQs)....

Do I need to fast for the race?
Not necessary. A fast definitely causes you to become weak with no more energy to walk or run. [Seems kinda obvious to me but....]

People with what disease cannot participate in the race? Those with life-threatening disease such as heart disease, high blood pressure, pneumonia are not allowed to participate. Others should consult with the doctor before participating. This event is also not suitable for people who have never taken regular exercise.

In case of rain on the race day, is there any assistance for participants?
Except for violent storm or other unmanageable incidents, the race will continue in spite of rain. This is considered normal in the rains.[i.e. if it rains, get over it?!]

As the race starts from early morning 2am and continues for 5-7 hours, what will happen if I do not have enough sleep? Not having enough sleep might affect you health for some degree. Although the race starts at 2am, it will not matter. ...Don’t worry. Simply join Standard Chartered Bangkok Marathon and you will find how wonderful a sunless running brings to you.
