Wow! is all I can say to start with. It looked fun and fast, but I didn't know how fun (and tiring) it really was. It was a very low key race with limited participants, but the most experienced person said it was right up there with the most difficult courses he had done. The run-ups were wood-chip (think course mulch) piles. Some were just up and over, but some were long enough that we ran along the top of them like running over the roof line of a ranch style house.
I did it on my bike that I am converting to a cross bike with some conversions yet to be done. The bike has a triple and I am thinking of making the smallest ring a 32t since I could have used something less than a 38 but larger than a 28.
Will post how future races go and maybe a pic of the bike when it is done.
