Coca Cola girls defending champions, Adi Cakobau School, will have to work extra hard this year after former athlete, Alena Vadrasalu has left the school system.

Vadrasalu scooped the Senior Girls 100 and 200 metres Gold Medals at the Zone and Coca Cola games last year, something fellow teammate Sera Tuinalase will try to retain this year.

Adi Cakobau still has the services of long distance runner and Pacific Games 3000 metres Gold medalist - Akesa Drotini, who is expected to feature in the 400 metres this year.

Tuinalase and Drotini will feature for Adi Cakobau in the two-day Triple N Zone which will be held tomorrow and on Wednesday at the TFL National Stadium.
