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.

About the Big Island International Marathon

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
