I’m Jusman — host of The Endurance Lab — where I combine research, real-world self-experiments, physiologic testing, and hard-earned experience to help midlife runners optimize performance, endurance, and longevity through health-focused and science-driven protocols. What’s new in 2026: The Endurance Lab Podcast In 2026, the channel expands into The Endurance Lab Podcast, where I interview leading experts, elite and everyday midlife athletes, and researchers shaping the future of human performance. Our mission is to deliver bleeding-edge science, tested training insights, and real stories that inspire runners to continue progressing in their 40s, 50s, and beyond. Personally, I ran my first marathon at 45 in 4:13. By age 47, I ran a Boston qualifying 3:05 marathon, as well as completed both a 100K and a 100-mile ultra trail race. I am also a RRCA certified Distance Running Coach. My next goal is to run a sub-3:00 marathon before I turn 48. Awin
