The online Ekiden registration process is structured to make it easy for each team member to register independently (rather than one person registering all four). Teammates can register by visiting the registration page and following the registration steps. Enter your name and birth date, and it will give you the option to either create a new team or join an existing team. When you type your team name, you should see it appear. Once you choose to add a teammate, you will be prompted to enter the remaining information. Only the initial registrant will submit payment for the Ekiden Relay Team. For each subsequent member of an existing Ekiden Relay Team, the payment total will be $0.

Conveniently sign up at the registration information page or visit Pacific Islands Club front desk to register in person. Credit card payments will be the only acceptable form of payment for in person applications at Pacific Islands Club.

There are no additional fees to register online, and we encourage all participants to register online for a seamless registration experience.

If you are unable to run, your entry fee will not be refunded. As stated on the application and instructions, race fees are non-refundable nor are they transferable from person to person or year to year.

Race numbers are non-transferable, and doing so will create confusion with the results. The Guam Ko'ko' Half Marathon & Ekiden Relay takes NO responsibility for a third party should a number be sold or transferred.

This year marks the 11th Annual Guam Ko'ko' Road Races. Each year the race grows in the number of participants and the added value for Ko'ko' runners -- from the giveaways and activities to the prizes and post-race party. Each finisher will receive an official Ko'ko' Race dri-fit t-shirt, a reusable event bag, access to the Post-Race Monster Bash and entry to win a roundtrip airline ticket on United Airlines to an Asian or Micronesian destination of choice, raffled off at the start of each race! In addition to all that, the Guam Ko'ko' Road Race is a signature Guam Visitors Bureau sports event that is professionally organized by the experienced team at Guam Sports Events, so you will not only have a safe and good time, the course quality and overall experience will be world class.

Running the Race

You must be at least 14 years-old on the day of the race to run in the Half Marathon or 11 years-old on the day of the race to run in the 10K Race or Ekiden Relay.

For safety and insurance reasons, music players and headphones are not permitted on the course. The Guam Ko'ko' Road Race is also one of the few occasions in life in which crowds will be cheering and clapping for you. Enjoy it!

The Ko'ko team loves animals, but for the safety of our furry friends, we ask that you leave them at home on race day. Pets will not be permitted on the course.

For the safety of all of the runners, we do not encourage strollers on the race course. However, if participants bring strollers, their child/stroller will not be registered, nor receive a finish time. Also, please start towards the back of the starting line to ensure you do not block other runners.

Runners of all abilities are welcome. We recommend that you line up towards the back of the start line and run on the right-hand side of the lane. Be sure not to stop suddenly or veer into the paths of other runners. If you're running with friends, run no more than two abreast. Doing so keeps traffic on the course moving smoothly. The half marathon course will stay open for four hours.

No. You will not be able to run the race without a race number. If you do not wear your timing chip, you will not receive a finish time. Race officials will remove non-registered runners from the course.

To ensure fairness, number assignments are made on a completely random basis when each runner registers.

Unfortunately, only one number is issued per runner. Lost numbers cannot be replaced under any circumstance.

Each race number (and corresponding timing chip) is assigned to you specifically. If you wear another person's number, your finishing time will be recorded under his/her name. Please do not mix up your race number and timing chip with someone else's.

Yes. All timing chips must be returned after the race. A designated area will be set up after the finish line for you to return your timing chip. A $20 fee will be accessed to the credit card used to registration for the race for any unreturned timing chips.
