KL marathon here I come!

I am registered for the KL marathon June 24th. Yes the full 42km and not the 21, 10 or 5km. Well my last pair of runners are well worn and has done its time. I got this pair of Brooks Glycerin at the Running Lab, Tropicana City Mall. Go there and there is a guy called Chong who will diagnose your running gait on a treadmill and the type of feet you have before recomending a type of shoe to you.
