Alison Miller

Bio

Alison Miller is a 46-year-old physical therapist and elite endurance athlete based in Aledo, Texas. A former scholarship soccer player at Texas A&M University, Alison discovered her passion for endurance sports after college, beginning with marathon running and qualifying for the Boston Marathon on her first attempt with a 3:28 finish. Her athletic pursuits expanded into triathlon, where she has completed 19 Ironman races, including five appearances at the Ironman World Championship in Kona, Hawaii. As a five-time Kona qualifier, Alison consistently placed first or second in her age group to earn her spots at the sport's most prestigious event. Alison transitioned into ultra running approximately 20 years ago, winning her first 50K trail race in Missouri's Ozark Mountains. Since then, she has conquered some of the world's most challenging ultra-marathons, including UTMB (Ultra-Trail du Mont-Blanc), Badwater 135, and the Cruel Jewel 100 in Colorado. She has claimed victories in several local and regional ultra races, including wins at Rockledge Rumble, Bridgeport Grasslands Marathon, Hell's Hills, and the Rattler in Austin. Currently, Alison is attempting the Grand Slam of Ultrarunning—completing Western States 100, Vermont 100, Leadville 100, and Wasatch 100 all within a single season. This rare achievement represents one of ultra running's most demanding challenges, requiring 400 miles of racing across seven weeks. As a practicing physical therapist in an outpatient orthopedic clinic, Alison treats athletes and non-athletes alike, bringing her personal understanding of endurance sports to her professional practice. She holds a degree in exercise physiology and has never used a coach throughout her athletic career, preferring to design her own training programs. Alison's approach to endurance sports emphasizes mental toughness, conservative pacing strategies, and the importance of community support. She credits her husband, also an accomplished Ironman athlete, as essential to her success both as crew support and as someone who understands the demands of elite endurance competition.
