Often described as the Super Bowl of trail running, the UTMB is a mountain ultramarathon that takes runners through three countries in Europe. Sections of the race loop through France, Italy, and Switzerland. The race route is 100 miles long (more than 171 kilometers).
With a total elevation gain of 10,040 meters (32,940 ft), the UTMB is one of the most difficult races in the world. While the fastest runners complete the loop in slightly less than 20 hours, most runners take 30 to 46 hours to reach the finish line. Many runners will have to run through two days and two nights in order to complete the race.
Many don't finish the race at all. These are called DNFs (did not finish). The DNF rate for UTMB is quite high. In 2024, the DNF rate was 36%. Out of the 2761 runners at the start line, 1001 of them did not finish the race.
This is Carranza's second time to run the UTMB. He ran it the first time in 2017.
"It’s a humbling and rewarding experience to have finished twice one of the most iconic and mythic trail running races in the world—the Ultra Trail du Mont Blanc (UTMB)," Carranza wrote in an update on Facebook after completing the race.
UTMB 2025 was won by Tom Evans of the United Kingdom (male division) and Ruth Croft of New Zealand (female division).
