My advice ? Be wary of your trailing foot and Don't freak out over this event. There are only a few competitors, the rest are there for the challenge and beauty of it.
Enjoy you fellow marathoners, These folks are best you'll meet anywhere, and everyone is willing to lend a hand, and they all look out for each other.
I'm sorry I'll miss it this year. I'll really miss it.
your training is done, Enjoy your taper. When you're at the starting line, DON'T LOOK UP ! You may strain your neck. Ha-Ha-Ha !
Enjoy folks... It truly is a wonderful experience !!!
