The series will continue over the next five weeks.
The events will be handicapped with the quickest guys and girls starting several minutes after the average riders.
The events are open to all eligible triathlon fraternity members and any new persons who have not competed before, and who would like to give it a go.
Sponsorship is by Westpac Bank and very worthwhile prizes of cycle gear with energy food munchies at the finish will be on offer.
The first event will be a 16km distance from Avarua out to Aroa Nui Hall at Arorangi and back which means cyclists will get to ride over the new seal outside the airport twice which will be 5km worth.
An 8km mark with arrows to turn at will be placed on the road at the turn.
Subsequent weeks will have distances of 16km and 20km as well as a full circuit of the island.
The Triathlon Association is grateful to Westpac Banking Corporation for sponsoring these events and cycling gear prizes will be on offer.
These races are a blast for people of any ability and many different people have won these events under the handicap system.
Prizes are not necessarily for the fastest time with first across the line and fastest improver usually rewarded.
The starts will be outside The Goldmine and Raviz on the inland side of the road and will finish at the same spot on the seaward side of the road.
