沖縄県 那覇市
Hilly
Warm even in December, and with plenty of climbing. It is usually talked about as a race for the atmosphere and the roadside support rather than for a time. Do not plan hydration and heat management the way you would for a mainland race.
Observed at Naha on the same date over the past 5 years
Finishing may matter more than the clock. Heat management is essential.
