The Hawaii Kai Ultra Run – XTreme 2018 is a great way to challenge yourself with any distance from 13 miles (Half Marathon) to 100 miles! Taking place in Kalama Valley on the far east end of Oahu this weekend, it includes “Heartbreak Hill” in the shadow of Koko Crater as part of a nine mile loop that takes you through residential Hawaii Kai.
