The plans and pendants I wish I'd had.
I'm Katie — a two-time Ironman finisher, US Masters Swimming coach, and personal trainer at a university wellness center. Endorphin Designs is what happens when those worlds come together.
It started with a charity race. My first triathlon was the Philadelphia Insurance Olympic, run as part of Team in Training to raise funds for the Leukemia and Lymphoma Society. I crossed that finish line and never looked back — two Ironmans, more half marathons than I can count, and coaching adult athletes through their first 500-yard swim, their first triathlon, their first marathon.
This shop exists because I kept noticing two gaps:
Adult athletes need real training plans. Not generic PDFs scraped from a fitness blog — actual structured programs built by someone who has stood at the back of the pool with a hundred nervous beginners and who has been the nervous beginner. Every training resource here is designed by a coach, for the athletes I work with daily.
Finishers deserve to celebrate. Medals end up in drawers. A delicate pendant engraved with 70.3, 13.1, or 26.2 becomes part of the everyday — wearable proof you did the hard thing. The motivational prints carry the same idea: the things you earn deserve to live somewhere you'll see them.
Whether you're learning to swim, training for your first race, or buying a gift for the athlete in your life — this shop was made for you.
Thanks for being here.
— Katie
