American runner Ben Dhiman claimed this year’s UTMB men's title in an unprecedented 18 hours 16 minutes 29 seconds.

After the race he uploaded his activity data to the social fitness platform Strava. Let’s take a look at his remarkable numbers.

His watch showed a distance of 169.97 km and total ascent of 9,686 m, roughly matching the official figures. Moving time was 18 hours 03 minutes, which means he spent only about 13 minutes in aid stations in total.

Look at his heart rate: an average of just 128 bpm, spending almost the entire race in Zones 1 and 2 — no wonder he picked up speed as the race went on.

His finish scored in both the UTMB and ITRA systems as well, at 995 and 992 points respectively — almost a perfect score.

After seeing his data, what surprised you the most?
