that's a very good question! Because some runners prepare for ultra trail running races( 50 miles,100 miles)
and will be on the mountain all night, so they must train for that :)
I am not preparing for a ultra race ,i did it just for the experience ;)

So then, now that you are experienced, will you do it again or stick to daytime?

surely i prefer daytime,but if a friend of mine will tell me " let's go for a night run" ,i will follow him,haha
