I will racing as a Cat-IV for the B-R. Has anyone on the forums raced in the B-R? How was the course. From what I read on the web-site (bikereg) it looks like it is going to be a tough race with some hills early on. What have your experiences been? Did you run a special set up for the dirt roads? I was thinking of going to a 25 instead of a 23. 55 miles is long for April in Upstate NY but who cares it looks like it is going to be a blast.
