Barbi and I rode Kaena Point this past Saturday on our mountain bikes. The course is in excellent shape. There is just one area of the washout that requires crossing on a 4" x 4" plank. You have a nice big rock to hold on to and it is pretty easy--we did it carrying our bikes.
More info is available on the race by clicking here.
Additionally, we have HURT Trail Series shirts available for $20. These are Patagonia silk weight capilene and are great training shirts and fun to wear around. These will be available at the race.
