meet the nutrition coaching team

I'm Alex, a registered dietitian and age-group triathlete and runner. It was the moment I crossed the finish line of Ironman Wisconsin that I felt my calling to create Alex Larson Nutrition.

The mission here is to support you as an endurance athletes with practical and simple nutrition advice for lifelong health and performance.

I want you to confidently fuel you bodies for your athletic goals while still eating like a normal human (let's be real, life is too short to eat like a robot). 

When I'm not working as a nutrition coach or squeezing in a workout, my life is centered around my family and raising my 2 little boys.

I'm Mary, a registered dietitian and a certified personal trainer. I have been fortunate to work in clinical and wellness nutrition, addition to working with athletes. 

I've been a long-standing distance runner after realizing the only part about softball I enjoyed was running the bases. I was a 3-time All-American in cross country and track and field at the University of Wisconsin-Eau Clare. I ran in the 2020 Houston Marathon in 2:44 and qualified and completed in the 2020 US Olympic Marathon trials.

You can find me chasing after my two little girls when I am not running or working. I also enjoy spending time perfecting sourdough recipes, cake decorating, reading for pleasure, biking, hiking, and pretty much anything outdoors. I embrace an all-foods-fit approach to nutrition and am overwhelmingly passionate about helping athletes fuel for training and life.

I'm Hanna, I am a registered dietitian and a certified personal training with certifications in corrective exercise specialist.

I'm a two-time All-American collegiate athlete in cross country and track from the Univ. of Wisconsin.

I have successfully competed in numerous triathlons and road races, including an overall female amateur win at Ironman Canada 70.3, 2nd place finish at Ironman Wisconsin (finish time of 10:08) and 13th overall female amateur finish at the Ironman World Championships in Kona, Hawaii (with a finish time of 9:55). 

I live in Minnesota with my husband, and when I'm not running or working, I enjoy playing in the kitchen dreaming up new recipes, diving into a good book, and helping fellow athletes follow and achieve their dreams!
