Honolulu Marathon Guide 2025: What Runners Need to Know & Why the Day After Is Perfect for Exploring Oahu

Every December, the Honolulu Marathon transforms Oahu into one of the most energetic destinations in the Pacific. As one of the largest marathons in the United States—and the biggest running event in Hawai‘i—the race attracts tens of thousands of runners, families, and supporters from all around the world. Many travel from Japan, the U.S. mainland, and across the Pacific to challenge themselves in one of the most scenic marathon routes on Earth.

Whether you’re a first-time marathoner or a returning Honolulu Marathon veteran, here’s everything you need to know—plus the best way to unwind and explore the island once the race is over.

How Many People Come for the Honolulu Marathon?

The event regularly draws 25,000–35,000 participants, including runners, walkers, and supporters. This surge brings a wonderful buzz to Waikīkī and the surrounding areas, with hotels, restaurants, and beaches filled with athletes preparing for the big day.

For many runners, the Honolulu Marathon is not just a race—it’s a destination experience. Because the course passes stunning locations like Ala Moana Beach Park, Diamond Head, Kahala, and Hawai‘i Kai, it’s a bucket-list run that blends competition with tropical beauty.

Important Things Runners Should Remember

1. Packet Pick-Up at the Honolulu Marathon Expo

Before race day, all runners must stop by the Honolulu Marathon Expo at the Hawai‘i Convention Center.
Here’s what to expect:

• Bring your ID and confirmation to pick up your race packet.
• You’ll receive your bib number, timing chip, and race swag.
• The expo also offers official merchandise, gear, and last-minute essentials.

2. Hydration & Heat Awareness

Even in December, Hawai‘i can be warm and humid. Runners should:

• Stay hydrated the day before and during the race.
• Use sunscreen and stay cool.
• Pace themselves wisely—Honolulu’s humidity can surprise even experienced runners.

3. Transportation & Start Line Tips

• The start line at Ala Moana Boulevard gets busy—arrive early.
• Many hotels offer shuttle information; always check ahead.
• Expect large crowds and road closures in Waikīkī, Ala Moana, and Kapiʻolani Park.

Why the Day After the Marathon Is the Perfect Time to Explore Oahu

After conquering 26.2 miles, your body needs active recovery—and what better way to decompress than exploring the natural beauty of Oahu? Most runners spend months training for race day but often forget to make time to actually see the island.

A relaxed, small-group Circle Island Tour is the best way to:

• Stretch your legs without overexerting
• Enjoy stunning views without driving
• Learn local history, culture, and hidden gems from expert guides
• Celebrate your accomplishment in paradise

From the North Shore surf breaks to the lush Ko‘olau Mountains and the famous Dole Plantation, Oahu offers a day-after experience that is both refreshing and unforgettable.
