Event details and schedule
Race will begin at 7 am with the 5K racers, followed by the 10K runners at 7:10 am. Both will follow the same course for about a mile where the trail will split and the 10K runners will continue on a longer course up through the ranch. Both races culminate with a run past "the lookout" at the ranch with sweeping views of windward Oahu and then itʻs downhill to the finish line.
Be sure to arrive 45-60 minutes early to get parked, checked-in, and receive your timing chip. This is a working ranch with challenging trails--bring the most rugged shoes you can find!
