Division Three inter-school athletics reach a crescendo in area four today when boys and girls champions will be decided at the Wan Chai Sports Ground. Thirty-six schools will compete in 50 remaining events after two days of competition last week. The top teams will be promoted to division two. German Swiss International School look strong in the girls competition. They can take full points in the girls' grade C 100m - their sprinter Natalie Armentrout ran a brilliant 12.94 in the heats, easily the fastest time. It was even faster than the best in grade A, Pang Ho-yee of Pui Tak Canossian College, who clocked 14.12 seconds. Natalie has a chance to break a three-year-old grade C 100m record today if she can beat the 12.90 seconds set by Lai Tsui-shan of Heep Yunn School. St Clare's Girls' School 400m runner Coco Chan Yee-man ran a speedy one minute 8.98 seconds in heats last week. The race for the fastest schoolboy in the division should be between Kuo Tsz-lo of Man Kiu College and Tang Kai-ting of Maryknoll Technical College. Tsz-lo clocked 11.92 seconds in the 100m heats last week, just behind Kai-ting's 11.72 seconds. The all-time grade A record is 10.51 set in 1996 by Wong Man-lung of Wah Yan College, Kowloon.
