Last school competition?

Today was the Geelong High Schools cross country event. A, R and C all competed. In probably his last event representing his school, A had a great run finishing 12th...just out of qualifying. R finished 16th and C, 18th. Her team however finished 1st....an aggregate score for the first 4 runners from each school. With 1st, 3rd, 15th and 18th they are off to Melbourne for the next level of competition.
