Hard-Easy Every Day: How Jim Dietz Maintains 1:20 Half Marathon Times in His 60s

Meet Jim Dietz, a 65-year-old retired TI engineer who's been defying age-group expectations with sub-1:20 half marathon times and consistent sub-18-minute 5Ks. In this conversation, Jim takes us back to the golden era of corporate running in the 1980s, when Texas Instruments funded a legendary distance running program that attracted All-Americans and near-Olympic-level talent.Jim's journey spans 45 years, from watching a New York City Marathon movie in college to becoming part of TI's powerhouse team that could take over entire races at Plano Pacers. He shares the untold story of corporate America's investment in employee wellness through competitive running, complete with national meets, sponsored travel, and workplace cultures that encouraged midday training sessions.After a 12-year hiatus where he gained 60 pounds, Jim returned to running at 55 and rebuilt himself into one of the most competitive masters runners in the Dallas area. His unconventional training philosophy—running hard every other day at sub-7-minute pace for 50-65 miles per week—flies in the face of traditional coaching wisdom but continues to produce remarkable results.Beyond the times and training, this episode explores the deep community connections that have sustained Dallas running for decades, from the consistency of Plano Pacers to the enduring friendships formed at White Rock Lake. Jim reflects on retirement, staying injury-free, and why he believes someone breaking the 2:30 marathon barrier locally could inspire a wave of similar achievements.Whether you're curious about running's corporate history, seeking motivation for masters competition, or wondering how to maintain speed well into your 60s, Jim's story offers both inspiration and practical insights from someone who's truly lived the sport.
