JAL Honolulu Marathon: Course, Route Profile & Map

Course & Elevation

You set off in the dark along Ala Moana Boulevard as the fireworks fade over the park. The opening kilometres pass the harbour and the Aloha Tower into downtown and Chinatown, then run along South King Street past landmarks in their Christmas lights – the Iolani Palace, the gilded King Kamehameha statue. Kapiolani Boulevard brings you back toward the water and onto Kalakaua Avenue, right through Waikiki between the hotels and the beach. At kilometre 12 comes the first Diamond Head ramp: about 700 metres at four percent, touching nearly eight.

Then the long eastern half opens up: through residential Kahala onto Kalanianaole Highway, which follows the coast out to Hawaii Kai. Between kilometres 24 and 30 the course loops through the neighbourhood streets around the bay's inland waterways before returning along the same highway – long straights, by now in the rising sun. Past the Waialae Country Club and the Kahala mansions, the second, shorter Diamond Head passage waits at kilometre 39 on the ocean side; the road then drops past the lighthouse and the final kilometres run along Sans Souci Beach and the Waikiki Aquarium to the finish at the Kapiolani Park Bandstand.

What makes this race unmistakable is its character as a festival of running: nearly half the field travels from Japan – JAL has been title sponsor since 1985 – many are first-time marathoners, and because the course stays open until the last runner arrives, the finish in the park is still celebrating into the early afternoon. Fresh malasadas wait behind the line.

Pacing Strategy

Pacing Honolulu is above all a thermal calculation. At the five o'clock start it is around 23 degrees with high humidity, and you run the first two hours in the dark – the best conditions of the day. From sunrise around seven, temperature and sun exposure climb steadily. Your goal pace therefore belongs in the cool hours, but under control: the huge field makes the opening kilometres crowded anyway, so no weaving – settle in patiently.

The race is decided on Kalanianaole Highway and the Hawaii Kai loop between kilometres 21 and 34: exposed straights with little shade, by now in the morning sun, and the trade wind can turn into a headwind on the way back. What counts here is a stable rhythm and drinking at every station – get through this stretch intact and you can bring the race home along the coast.

The classic trap is the pace of the cool opening hour: run the dark, flat kilometres like a PB chase and you pay double in the heat after kilometre 30. Both Diamond Head ramps are short – cap the effort, roll easy over the top, and use the descent at the lighthouse to set up the finishing kilometres.

Training plan for JAL Honolulu Marathon: 12-week build

As an age-group runner, plan for four to six hours – and since there is no time limit, deliberately longer race days are perfectly legitimate here. The effort is uniformly aerobic: apart from the two short Diamond Head ramps there is no change of terrain, so only you hold your pace.

The most important building block is adaptation to heat and humidity. For a December marathon, the key training weeks fall in late autumn at home – targeted heat exposure in the final three to four weeks (sauna after runs, deliberately overdressed sessions) bridges the gap. Practise your drinking and electrolyte strategy in training too: in tropical humidity you lose far more fluid than in a northern winter.

Carry the volume with easy long runs, several finishing progressively: the second half on the highway demands that you hold rhythm as fatigue builds. Sharpen with threshold blocks on flat ground; strides or short hill pickups cover everything the course's brief ramps will ask.

Two quirks deserve their own attention. The five o'clock start means getting up in the middle of the night and running in the dark – put some long runs in the early morning hours so your body and breakfast routine know the drill. And in the dark, crowded opening kilometres, start by feel rather than trusting the watch alone.
