The HKUR – Kalama Valley

Simply show up and sign in with your own start time at the start/finish tent. (Most people start between 3 and 7 am on Sat. morning)

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

** Takes place near Sandy Beach in Hawaii Kai. A (start/finish/aid station) tent will be set up at Kalama Valley Park on Kealahou Street. Ice, drinks, and food will be provided. It is essentially in the middle of the course. You will first run an out and back towards the back of Kalama Valley, then another out and back towards the ocean, so there will be plenty of contact and support from other participants. Each full loop is 3.34 miles (3 loops is 10 miles). Course will not close until the last person finishes on Sunday night.

**Certificates and custom awards to all registered finishers. Random gift giveaways to all participants and volunteers from our generous sponsors. ** Note: This event is a Marathon Maniac, Half Fanatic, and 50 States Marathon Club qualifier and will count towards your totals. If combined with the Honolulu Marathon, you will qualify for the Marathon Maniacs.
