The Rock Chalk gravel road race is this Saturday. The promoter sends this: "if more than 20 cat 4/5 show up to the race, I will split the field into a men's open and a cat 4/5. The race should be fun, informal, and cheap. The course consists of mostly flat sections with two climbs. New gravel has been laid down in some areas but the roads are mostly buff smooth gravel."
Also, Sunday features a cyclocross race at Clinton Lake: Sunflower Cross.
