Ten photos from the UTMB®: FROM DUSK TILL DAWN

Covering a distance of 171 kilometers, climbing more than 10,000 meters of vertical, spending one and sometimes two nights out on the race course, for runners participating in the 2017 edition, the world's most famous trail run lived up to its reputation. An incredibly talented lineup of top runners led the race, followed by thousands of participants pursuing their dreams. Everyone experienced difficult conditions in the mountains at some point, and made a colossal effort to reach the finish line. Here is a quick review in photos…
