Big Island International Marathon
Race Day Weather
Warm start, chance of rain
A warm 74°F start means heat management is critical — consider dialing back your goal pace by 10-20 sec/mi. Temperatures rising to 83°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. There's a chance of rain, so have a backup gear plan ready. Moderate humidity at 79% is worth noting for effort level, especially in later miles.

Race Info
The Big Island International Marathon is held each March in Hilo, Hawaii. The marathon starts at 6:00 AM in the garage of the Hilo Hawaiian Hotel on Banyan Drive and finishes on the lawn behind the hotel. The course is two out-and-backs: one north along Highway 19 to a turnaround just past the Hawaii Tropical Botanical Garden, the other along Kalanianaole Avenue past the Onekahakaha and Richardson beach parks. A half marathon, 10K and 5K start from the same hotel the same morning, and the course closes at 1:00 PM. Source
