Summary: Situated in the mountains above the city of Honolulu, this course is characterized by its latticework of roots across the single track trails. Runners cover the 100 milers over the course of 5 loops with some partial out and backs, gaining and losing 24,500 feet, crossing 20 streams, and of course, running over countless roots, rocks, puddles and “mud wallows”. It’s certainly not for the faint of heart and takes lots of perseverance and an adventurous mindset.

Lessons Learned from Race Reports

Average temps listed are for the city of Honolulu. Expect lower highs and lows, more precipitation, and high humidity (the race is in a rainforest)
The dense canopy in the forest causes shorter daytime hours than the sunrise/sunset listed, so be aware of when you need your headlamp during the race
Very little of the course lends itself to a consistent stride – be ready to be consistently inconsistent in how you run and navigate the footing and elevation changes of the course
There are wild pigs in the forest – exercise caution if you see any, especially any momma and baby pigs
Mosquitos are a factor, especially in areas with little air movement
Dehydration and hypothermia are big risk factors for runners in this race because of the hot and humid days and cooler night temperatures
Of the two stream crossings, one is technical and another is not. Be ready to get your feet wet (if they aren’t wet and muddy already), and be ready to cross scattered and slippery rocks
Hiking poles are allowed (and by the looks of course, aren’t a bad idea!)
Be sure you know the runner, pacer and crew rules in the Book of Hurt
Lots of other day hikers out on the trails, so be aware and respectful of other trail users
Sauna sessions as part of training are helpful because of the high humidity in the race
The course takes constant mental focus because of the technical footing and twists and turns
If you don’t run well with wet feet, have a plan for changing socks and shoes often to have dry feet
The first climb starts out in in the dark and will likely feel crowded with runners all in a line, so if you want to be in front, you’ll need to get out fast. If not, do your own pace and don’t be rushed by others pushing from behind.
Lots of runners fall apart on loop 4, when the darkness settles in and they still have 40 miles left
Know that your pace will slow, likely considerably, once it gets dark. Be prepared to hike.
If it’s muddy, which is likely, the mud gets worse as the day progresses because of so many people running over the same trails over and over again
Have a very strong headlamp – seems intuitive and normal for any ultra at night, but several races reports noted having a weak headlamp and really suffering because of it.

Tips from Coach Masazumi:

Trekking poles save you, so train how to use them before the race if possible. HURT 100 is very technical, and they help place your steps stable. Many use it regardless of whether a runner is fast or slow. Last year, 2nd place runner was using them in his last lap.
In addition to Sauna, try the fitness gym. It’s warmer than outside and easier to stay longer than in the Sauna.
Loop course is one of the big factors of high DNF rate. It’s getting harder to start another loop when you are tired. Be strong and stay focused on your goal.
