Tantalus 10-Mile Challenge

Lace up for an unforgettable challenge at the Tantalus 10-Mile Challenge, set for Sunday, September 27, 2026, in the stunning landscapes of Honolulu, Hawaii. This demanding 10-mile road race, organized by the Mid Pacific Road Runners Club, promises a truly unique experience with its notoriously hilly, one-loop course around Mount Tantalus. Runners will conquer approximately 1500 feet of elevation gain through a lush rainforest, enjoying incredible panoramic views along the way.

The race kicks off at 6:30 a.m. on Makiki Heights Drive near Halau Kumana School, immediately heading uphill for about five miles along Makiki Heights Drive and then Tantalus Drive. Prepare for a thrilling descent on Round Top Drive for over four miles, before a final uphill push brings you back to the finish line near the starting point. Participants often praise the course for its "beautiful views, lots of shade and breeze," and the refreshing "air filled with eucalyptus smell & spectacular views". For those who anticipate a finish time over 2.5 hours, an optional early start at 6:00 a.m. is available, though it requires a flashlight or headlamp and disqualifies participants from overall or age group awards.

Typical race day conditions in late September in Honolulu feature highs around 88°F and lows around 75°F, with only a 4% chance of precipitation. The Tantalus 10-Mile Challenge offers more than just a race; it's an opportunity to test your limits amidst breathtaking Hawaiian scenery.
