Get ready for an early morning adventure at Kailua Beach Park in Hawaii with this 4.4-mile out-and-back beach race that kicks off at 6:30 a.m. (arrive by 5:30 a.m. for check-in and same-day bib pickup). You'll run along the scenic shoreline to a turnaround point near Kaneohe Marine Corps Base, potentially wading through shallow water depending on the tide, while trying to catch the "shark" that gets a head start—plus stick around after to celebrate with awards for top overall finishers and age-group winners, followed by a potluck social.
