A warm, pre-dawn-start marathon through Honolulu and around Diamond Head, with no field limit and a famous fireworks start.
Sunday 13 December 2026
About 24 weeks away · 168 days · projected from the usual race weekend
Training for the Honolulu Marathon comes down to two things: building the right work in the weeks you have, and pacing it sensibly on the day. Our free generator counts back from race day and sets your plan length to suit how much you are running now — so you are neither under-prepared nor stretching a short build over too many weeks.
If the Honolulu Marathon falls in a warm part of the year for you, plan for the heat: even a few degrees changes a realistic goal pace. Our heat adjuster shows how much to give back, and our course pacing guides cover the elevation and race-day strategy for marathons we have profiled in full.
