Lucong Geng used one pair of

Mount to Coast S1 to cover over 600 miles.

In the spring of 2024, Asian ultrarunner Lucong Geng reached the northernmost point of Scotland to run the MTC JOGLE, a multistage ultra to the southernmost point of England. Over 17 daily stages he ran 854 miles and 54,475 feet of elevation. From east to west and north to south, Lucong broke the Asian record eventually and ranked the 3rd in the history of the race, with one pair of S1s to cover 620 miles of his journey. That’s more than just running. That’s ultrarunning.
