YOUR HYROX WORLD CHAMPION!

Watching Alyssa’s journey has been nothing short of inspiring. The work, the discipline, the sacrifices, and the relentless pursuit of getting better all led to this moment.

But what makes this even more special is the person she is when she’s not competing. Alyssa is a light in the gym, a role model, and someone who makes everyone around her better.

Congratulations, Alyssa Mcelheny, on becoming the HYROX World Champion!! We couldn’t be more proud to have you represent our community 🧡
