Big crowds are already coming out for the Cyclocross National Championships races going on this week in Bend. Doug La Placa with Visit Bend, says the big races will be this weekend: “The crowds have, again, exceeded out expectations. At this stage of the week we’re still in somewhat less prestigious racing. So we’re not expecting big crowds, but we still had over 1000 people watching the races. Which is an indicator that we’re expecting enormous crowds on Friday, Saturday and Sunday.” The National Championships will go through Sunday. With temperatures expected to be in the mid to high 40's, participants expect some muddy racing conditions in the Old Mill District.
