Hawaii Kai Xtreme 2017
Challenge yourself with the longest run of your life – Whether it be a Half Marathon, 30K, Marathon, 50K, 50 Mile, 100K, or 100 Miles. You choose the distance.
The Hawaii Kai Ultra Run takes place semi-annually on the far east end of Oahu. This fun event is designed to challenge runners to take on new distances with the support and camaraderie of fellow runners. Official times are recorded for qualifying purposes for the 50 States Marathon Club, and Marathon Maniacs. There are no age group awards. It’s a personal challenge. Finisher certificate and customized award for all registered finishers.


In 2013 we had two events in Kalama Valley ~ July & December.  And, in 2014 and 2015,  one event in Kalama Valley. The XTreme course changed in 2017 to include Heartbreak Hill and a loop through Hawaii Kai, making it truly… XTreme!  We have continued twice a year since then.
In the future, a a third event will be added – a competitive RACE around Hawaii Kai Towne.


The HKUR – XTreme date for 2020: July 18 and 19

Choose your distance: Half Marathon, 30K, Marathon, 50K, 50 Miles, 100K, or 100 Miles. Choose your own start time: EARLY start option is available from 3AM on Saturday morning. Simply show up and sign in with your own start time at the start/finish tent. (Most people start between 3 and 7am on Sat. morning)

Other options include any time on Saturday afternoon or even Sunday morning.

Check-in at Kalama Valley Community Park (555 Kealahou St. Honolulu, 96825 – It’s approximately 13 miles and a 30 minute drive from Waikiki.)

NOTE *** The XTreme has been changed this year to the winter course: 3.3 mile loop – up and down Kealahou Street. There are no turns. Only two turnarounds at each end. The aid station is postitioned in the middle of this loop. Therefore, you will pass by it after 1.1 mile and 2.2 miles.

COURSE MAP:  https://goo.gl/maps/YA6HRho5ruhhY8G78


I want to run the marathon distance, but I’m not sure I can finish it. Would you allow me to opt to for the 30K distance if I feel I won’t be able to finish the marathon?

If you are debating between two distances, always choose the lesser one to sign in with. In this case 30K. If you are feeling good – you can always run longer and finish the marathon distance. On the other hand, if you choose the marathon, and only finish a 30K, then it will officially count as a DNF (Did Not Finish). We do this for official record keeping purposes (ex.- Marathon Maniacs, 50 States Club, ect.) as we need to keep track of how many people start and finish for each distance. Regardless of the distance you finish… you will receive both a Finishers Certificate and custom finishers award for the distance finished!

Where do we park? Can I leave my things somewhere? 

There is street parking on Kealahou St. directly in front of Kalama Valley Park.
Map location: 555 Kealahou St. Honolulu, HI 96825
Some participants have used their car as a personal aid station. You can do this. However, if you would like to leave a gear bag or a cooler with drinks and food at our main check-in canopy tent – you are welcome to do so. Please label it with your name for easy identification.

What’s your recommended start time? What’s the earliest I can start? It says 8:08 am on your website. Can I start my run Saturday night? say 7 pm? Can I start on Sunday instead? What’s the latest we can run in the day? 

You can start anytime on Saturday… morning, afternoon, night… or even anytime on Sunday. We’ll be there setting up at 3 AM on Saturday. Just sign in with your starting time. We keep track of time for official record keeping purposes, and publish them on our website for the same reason. However, they will not appear on your Finisher Certificate or custom award. This is not a race. It is a personal challenge. For that reason, we also do not have cutoff times. Rest when you need to, and then continue your run/walk.

How are the laps recorded, timing chip, manual? Just curious about keeping an “official” time. How will that be done?

There is no chip timing. It is a personal challenge, not a race. So, the honor system is in place. How does that saying go?… “If you cheat, you’re only cheating yourself.” After you sign in with your starting time, you will check off each time you complete a loop. There may be volunteers on hand to assist you. However, if not – just check it off yourself. When you finish, you will record your finish time, and collect your Finishers Certificate.

Are there restrooms available near the course, even during the night?

Restrooms are available 24 hours at Kalama Valley Park

Do I have to worry about cars or cross traffic?

Please obey all traffic rules, including crosswalks and signals. This is not a closed course. It’s open to all normal traffic. You may run/walk on the sidewalk or edge of the road. It is advised to run facing traffic. This is considered safer as you won’t have cars coming from your back. It’s a residential area, so the traffic is somewhat light, especially on the weekend.  However, there can be a good amount of cars headed towards Sandy Beach later in the morning/afternoon.

Do I need headlamps or flashlights?

If you are running during dawn/dusk or darkness, then reflective gear is strongly recommended. Along with a safety vest and/or flasher or small flashlight. There are street lights in this residential area. However, there are a few sections without. And, greater visibility as a runners is important. Especially if a driver may have poor, or impaired vision. As the saying goes… “Better safe than sorry.”

I wanted to order a t-shirt, but did not see how to do that when I registered.

Purchase of a optional t-shirt was not available online. However, we will have short sleeve shirts available at the event for $25.

Finishers receive a certificate and an award?

All participants will receive a Finisher Certificate on site, for the distance they complete. Custom made awards will be mailed, and have the participants name and distance.

If you have any additional questions, please don’t hesitate to email, call, or text.

Mahalo to everyone participating in this years event.

There was a record turnout – 81, with runners (and walkers) finishing distances from a Half Marathon (13.1 miles) to 100 Miles! Yes, we’ve been waiting for someone to finish 100 Miles on this course for years now, and Blaine Lints came through big time, finishing in just under 21 hours! We also opened it up to back-to-back days with Les Omura and Ruth Modisette both finishing the Marathon x 2. The next HKUR event will be on December 15 & 16, 2018 in Kalama Valley, and again in July 2019 with the XTreme course.

We couldn’t do it without our sponsors. Mahalo!
