UTMB is recognized as the pinnacle of trail running, drawing the sport’s most elite athletes and thousands of passionate fans to the Mont-Blanc region each year. Known as one of the most demanding races in the world, the UTMB challenges competitors with grueling climbs, extreme weather conditions, and 9,900m elevation gain.

Ruth Croft credited the newly launched Amazfit T-Rex 3 Pro with supporting her performance during the race. Tested by elite athletes ahead of its release, the watch’s endurance-focused design, advanced GPS technology, and long battery life helped her monitor pace, heart rate, and performance readiness throughout the extraordinary journey.

In addition, Ruth used the Amazfit Helio Arm Band and Helio Ring, paired to her watch, to track real-time heart rate during the race. Leading up to the event, she used the Amazfit Helio Strap to monitor her recovery, resting heart rate, and sleep.

“I couldn’t have asked for a better day. I was able to manage the cold weather conditions through the evening, and then get back into race mode once day broke. It was made even better getting to share this lap around Mont Blanc with my family and friends.”

Amazfit athletes made their mark across the 2025 UTMBraces. American ultra runner Rod Farvard also relied on the Amazfit T-Rex 3 Pro, paired with the Helio Strap and Helio Ring, to secure the ninth place on his birthday in 21 hours, 18 minutes, and 24 seconds. Rising talent Rosa Lara Feliu used the Amazfit T-Rex 3 Pro and Helio Strap as well to push her way to a strong seventh in the OCC. Together, their performances reflect Amazfit’s support for athletes on the world’s most iconic trails.

Amazfit is committed to empowering athletes with the most advanced outdoor wearable technology. During UTMB week in Chamonix, Amazfit previewed the T-Rex 3 Pro ahead of its official launch and showcased the Helio Strap through athlete meet-and-greets, community activations, and hands-on product demonstrations.

This achievement adds to Amazfit’s growing investment in performance sport, all part of a long-term strategy to create products and programs built for athletes, by athletes.
