Hey Steve,
Being the first year, I have no idea what to expect for this race. I think that the combined cat 4/5 and Masters field will be the biggest field out there. That being said, I'd be surprised if the field got over 40 riders. A typical cat 5 rider in the Inland NW would be competitive in either the master's or the cat 4/5 field. You should come ride with us sometime. I think I saw that you're registered on our new site. Keep checking back for updates on our weekly club rides. We're normally pretty laid back
