Race with river raft trip as prize?

[Michelle Lowry]

I remember looking at a race in Utah with a river raft trip for 2 as a prize, but I don't remember what race it was or what month it was in.  I just remember thinking it'd be cool to try to win.  Anyone know what race this is?

The Kanab 10K has a river rafting trip as its prize.  The whole value of it is over $1000 - very cool.  I won it this past year.  It is only for 1 person - not so cool.  So I can either go by myself or pay for my wife to go with me; so basically a meaningless prize since I don't have money floating around.  I would have rather had won the 2nd place $100 dollars.
But a great prize if you are planning a river trip anyway.
The race is usually Mother's Day Saturday.
