We are considering this race, as are some of my fellow team memebers. Having done it in the past, I know how much fun it is. But we are honestly waiting out the weather. We all raced at the Gallop this year and I can only speak for myself, but I do not want to do that again. It trashed, and I mean trashed our bikes. It was a very expensive race for us. Not to mention the trail damage.
So, if you are willing to change the course, to avoid riding through sections of the trails that you feel might be:
a. further damaged
b. really muddy
I say go for it, and it would probably swing us in the direction of signing up for sure.
