Big Island triathletes Susan Nixon and Helgi Olafson pause for a photo with some of the participants in Hawaii Preparatory Academy’s Keiki Triathlon Sept. 29. Olafson and Nixon motivated and supported the young triathletes, who swam, biked on a grass course and ran on the school track. About 80 students in grades K-5 participated. Big Island triathletes Mark and Sylvia Ravaglia also were on hand to motivate and support the youngsters. Betsy Tranquilli, HPA’s Lower School physical education teacher, organized the event.
