The best marathon in the most beautiful city in the world! Perfect for beginners and those chasing PB’s.

Great and mostly flat race for any marathon runner. The views were just stunning on either side of the road whether the blue sea, green hills, local shopping strips or picturesque marinas.

You're running in the middle of the night, so don't expect a lot of sightseeing. However, the course is still quite interesting and it's one big loop so you don't have to run back and forth anywhere. 
I found it quite charming and really liked glimpses from behind the darkness; schools, stadiums, fountains, monuments, fields, forests, rivers.

I am not entirely sure whether it was me being better prepared or the weather was different, but I found running KL Marathon a bit easier than Singapore. Still, it is not easy and if you've never run in hot ad humid conditions, you might be up for a very unpleasant surprise.

It is very difficult for foreigners to register unless you can read Korean, have Korean address, phone number and bank account. Information in English is very limited however, if you somehow manage to do it you won’t be disappointed. In Seoul you will be running next to all the best and most interesting places. No skimping on sightseeing. The course is is also flat and wide, so get ready for your next PR!

It is not a place to run for a faint-hearted. The heat and humidity will get you well before you start gun.
