This Honolulu ultra offers seven distance options ranging from a half marathon to 100 miles, giving you flexibility to choose either organized wave starts at designated times on Saturday and Sunday mornings or your own custom start time at the start/finish tent. If you're aiming to qualify for a HURT event with a 50-mile, 100K, or 100-mile entry, you'll need to select a wave start for official timing certification. Just keep in mind that to avoid course cutoff times, you must begin by noon on Saturday, and all distances must start by noon on Sunday unless you've arranged otherwise with race organizers.
