SWIM (2.4 Miles):

Without a doubt, the most emotionally charged mass swim start in the sport, thanks to TV helicopters, enthusiastic spectators and the sun rising over Hualalai Volcano.

With waters a balmy 79 F, wetsuits are not permitted in the single-lap course in Kailua Bay.

Currents can be a factor, so a few pre-race practice swims in the bay are advisable.

BIKE (112 Miles):

As riders make their way north along the Queen Ka’ahumanu Highway, from Kailua-Kona to the turnaround at Hawi, they can be exposed western and northern coast of the Big Island.

The winds can vary in intensity from steady to heavy blasts that can blow a rider across the road.  For this reason, disc wheels are not permitted.

The winds can subside during the gradual climb to Hawi.

The winds usually pick up again once athletes make their way back to sea level on the Kohala Coast, en route back to T2.

RUN (26.2 Miles):

Finishing the bike is a bittersweet victory.

After a draining bike leg, your reward is a very hot marathon.

After making it out of T2, runners will wind through town before taking on Ali’i Drive, where spectators will pack the roads.

Athletes will then re-trace their steps, climb up Palani Road to the Queen Ka’ahumanu Highway to make their way to the Natural Energy Lab.

Unless cloud cover or nightfall spares you, anticipate high heat and humidity.
