Katharine Moustakes
Hey there!

It's me, Katharine.

KATHLETICS was started by a

non-athlete turned strength and outdoor endurance enthusiast. I've spent 7+ years dedicating myself to becoming a multifaceted personal trainer and running coach.


I understand that fitness is not your whole life. Fitness is a PART of your life. I approach training in a way that adds value to your life and longevity, so you can enjoy being active whether you're romping around in the mountains, playing with your kids, or signing up for your first 10K race.

I serve as an outlet for you to gain strength, knowledge, and confidence both in the gym and on the trails.
