A flat course ruled by heat
Typical sessions
Tropical heat and humidity, starting near 23°C and climbing past 28°C as the sun rises
A 5:00am pre-dawn start in cool dark air that tempts a fatal fast opening
The exposed Hawaii Kai out-and-back, the hottest stretch, hitting just as the sun comes up
Diamond Head, the one real hill, climbed twice, the second pass when you are hot and tired
What your weeks look like
Typical sessions
Warm-weather long runs of 25-30km in the heat of the day, rehearsing hydration and dousing
Marathon-pace long runs of 28-35km, some at your heat-adjusted goal pace
A 2-3 week heat acclimation block timed to peak in the final few weeks
Weekly tempo and threshold work to build the aerobic engine underneath
