USA Track & Field lost two giants of the sport in the past week with the passing of Air Force Academy head coach Ralph Lindeman and Mt. San Antonio College men's head coach Ron Kamaka. Lindeman, 70, had served as the head coach at Air Force since 1989 and led the Falcons to numerous conference championships and guided dozens of NCAA Division I All-America athletes. He was an integral part of USATF's men's development structure, acting as chair of the hurdles subcommittee for seven years, and he oversaw video analysis at U.S. championship meets. In 2018, Lindeman was the men's head coach for Team USATF at the World Indoor Championships in Birmingham, England. He also served as the jumps, pole vault, and decathlon coach for Team USATF at the 2004 Olympic Games in Athens, and as an assistant men’s coach for Team USATF at the 2007 World Championships in Osaka, Japan. In 1999, Lindeman led the U.S. men's team at the Pan American Games, and he was on the staff at the 1992 World Junior Championships in Korea. Lindeman was the Coaches Advisory Committee Chair from 2011-14 on the Coaching Education Committee and was President of USTFCCCA’s Division I Coaches Association from 2001-2003. He was a graduate from Arizona State University and was a high school coach before joining the staff at his alma mater in 1980. He then coached at Arizona and Long Beach State before taking the helm at Air Force. Lindeman and his wife, Cindy, were married for 50 years and had two children and six grandchildren. Information about services for Lindeman may be found here. Kamaka, 59, became head coach of the Mt. SAC men's program in 2013 after joining the school's staff in 2008. He led the men's team to three California community college state championship titles and earned several Coach of the Year honors. Prior to his time at Mt. SAC, Kamaka served as an assistant and associate head coach at Cal State Fullerton for 12 years. As a high jumper, he won a state community college title for Santa Rosa Junior College and then went on to compete for Arizona State University, where he had a personal best of 2.22m/7-3.25. A native of Hawaii, Kamaka suffered a bodysurfing accident in his home state in 1990 that left him a quadriplegic, but he found his calling in teaching and coaching, inspiring students with his love for life and his wealth of knowledge. He was a familiar presence at the prestigious Mt. SAC Relays, ensuring a good experience for athletes from high school to the elite level. He and his wife, Lynda, were married for 25 years. Services are pending.
