It looks like experienced junior boys will only be allowed to race in the first race--"Cat 4/5 with five or more races." The Juniors race says "Age 14-18 with less than 5 races."
Anyone know if this is true? My son is Cat 4, racing age 13. He had fun at the Early Birds last year, but I don't think I'll be able to get him up early enough on a cold morning to get warmed up for an 8:30 race that may or may not have any other juniors.
