R1

In the spring of 2024, before the shoe’s official launch, British ultrarunner Justin Montague took one pair of R1s to the northernmost point of Scotland to run the JOGLE, a multistage ultra to the most southerly tip of England. Over 17 daily stages he ran 854 miles (1,374 km) setting a time that was almost 40 hours faster than the previous record, and he broke each day’s individual stage record along the way.

That result was just a warm up. Since then, the R1 has guided athletes to countless personal, national and world bests, culminating in two of ultrarunning’s most prestigious records. First in spring 2025, US runner Meg Eckert covered 603 miles to shatter the women’s six-day world record. Then, less than a month later, Belgian endurance athlete Matthieu Bonne broke the 29-year-old 48-hour world record with 301 miles. Records are there to be broken and the R1 is here to R1p them up.
