I've completed 2 full marathons, but both were Sundown 42k's.
From what I have read, some people find Sundown tougher due to the late night fatigue effect (and overhead bridges previously).
But I also thought that StanChart is really a much hotter race since most of us will have to do it till 10am or later.
That would really zap the energy level, for me at least.
Wanted to find out from those who have done both - which is a faster run?
Also, I know there's really no 'easy' marathon, but
