We’re thrilled to announce a dynamic partnership between The International Running Expo (IRX) and Charlie Sarmiento, founder of VTX and elite endurance athlete. Charlie has completed over 30 ultramarathons across nine years, representing Guatemala at the Trail World Championship in 2018 and ranking among the top 150 globally. Most recently, he conquered the Xtri World Championship at Norseman 2025 in Norway.
VTX is a pioneering sports tech platform that uses the proprietary VTX Score to connect endurance athletes with funding opportunities. Through the VTX Score, athletes combine competitive performance, social presence, and training activity into a single comprehensive score. This collaboration brings VTX to IRX’s global stage of 6,000+ industry leaders, brands, and innovators, spotlighting the future of runners who want support for their upcoming competitions. Charlie is also the author of The Real Ultraman, where he shares a system he created to rewire the brain based on his journey in sports to heal his soul and rise like the phoenix.
As the ultimate business event for the running industry, IRX provides a space where innovation meets inspiration, uniting athletes, brands, and technology to shape the future of running.
