Customer Reviews

As a cyclist preparing for my first Gran Fondo, I was overwhelmed by all the fueling advice out there most of it felt generic or made for bodybuilders, not endurance athletes. Triforge changed that. Their curated product selection, especially the gels, gave me confidence to fuel properly during long rides. Plus, the educational content actually explains the 'why' behind every recommendation, which helped me plan smarter and ride stronger

Training for my first triathlon felt like entering a maze so many brands, products, and contradicting advice. Triforge helped simplify everything. I found fueling products that actually work for endurance, and their blog broke down complex topics into things I could apply instantly. It’s not just a store, it’s like having a smart training partner in your pocket.

I’ve been running marathons for a few years, but I always struggled with mid-race fatigue. Since using Triforge’s fueling recommendations and products, my energy levels are way more consistent. What I love most is that they only feature brands that are legit for endurance sports no gimmicks, just proven stuff.
