Hi Tri Series

Untitled design(8).png

The Hi Tri Series was started by Ben Williams and Manu Shelley, in an effort to combine multiple triathlon races and training programs under one umbrella.

Ben, who owns the Hawaii Triathlon Center, has long been an advocate for Triathlons in Hawai'i, especially in youth development.

Manu comes from a race timing background and teamed up with Ben to promote and develop triathlon activities in Hawai'i.

Together the two of them are on the forefront of keeping triathlons relevant in Hawai'i and promoting the sport to our upcoming generation.

What We Do?

Introduce the sport of triathlons to our upcoming generation


Stage several events throughout the year for competitions.

Offer year-round training opportunities for adults and youth.


Remain focused on our kuleana to support our local community.
