The Course

Okinawa International Triathlon run course

2 small loops + an out-and-back
· Most clocked around 9.4-9.7KM.


7 loops to 5 loops
Compared to last year’s bike course, the route was extended a little each way to make each lap longer (7.6KM), allowing athletes to do two fewer loops (and agonizing bridge climbs) this year.

Duathlon to Triathlon
Inclement weather during the days leading up to the race last year meant the swim was cancelled. The run-bike-run format took place in stifling post-typhoon heat and humidity.

This year, with the race date moved from mid-June to late May, the race organizers all but guaranteed better weather before the start of typhoon season.

Last year, transition was in the parking lot of Wakasa Park – right at the base of the climb up the bridge. 

This year, transition was relocated a couple hundred yards to the Naminoue Driving School. We didn’t have a swim last year but for both years, the swim start was at Naminoue Beach and we finished at Umisora Park.

Love It

Spectator Friendly
The good thing about race courses with multiple loops! The swim start, transition area, and finish chute are all within 1KM! Plus, plenty of opportunities to watch parts of the bike and run course. For athletes, it’s great to have so much support along the route – there
was even a nice man with a garden hose spraying runners past the Loisir Hotel!

One of the Okinawa International Triathlon’s biggest draws is its convenient location in Naha, the capital city of Okinawa. Hotels are a plenty nearby the race site and provide accommodation for all budgets. This is about as easy as it gets for a triathlon in Japan!

To race venue…
• From Naha Airport: 10-15 minutes
• Camp Kinser:
10 minutes
• Camp Foster:
30 minutes
• Kadena:
40 minutes
• Camp Schwab:
1 hour

Age Grouped Bibs
If you’re competitive, this makes it easier to pick out who you need to chase down! The first digi on each bib indicated age group (in increments of 10).

Great Course
There’s no denying the beauty of racing in Okinawa – the crisp open waters, the blue skies, and island vibes unlike mainland Japan. Hard to beat!

Needs Work

Swim in/out
Going in and out of the waters was a little tricky – there were a lot of rocks making it difficult to get a good start, nonetheless dolphin dive into the swim.

To make matters worse, we had to repeat the same dance again upon exiting the waters once after lap one, re-entering the waters for lap two, and exiting the waters again after lap two.

2 laps on the swim, 5 laps on the bike, 2 (short) laps on the run.

If you weren’t counting your laps, taking a look at your Garmin every so often, and watching the volunteers with signs carefully, you could miss a crucial turn! Honestly, 5 laps is really about the maximum number of laps any race should consider implementing.

The Naha Beachside Hotel is a simple, no frills hotel by Naminoue Beach. Lives up to its namesake, boasting very close access to the beach and boardwalk.

Walking distance to and from the race site – downtown Naha is a short cab ride or a leisurely walk away. From the airport, I rode a jumbo taxi with my bike in a Scicon and paid ¥1,300.

• Rent a mama chari bicycle for free (up to an hour)  – useful to explore the area or grab groceries (or a cheap meal) at the nearby store.
• Rooms vary greatly in size but generally run small.
• Simple but filling buffet style breakfast available.
