About

Hi, I’m Romain, a trail runner.

In three years, I finished three of the four races on this site. Somewhere on those trails, one question stuck with me: how many people have actually finished all four? UTMB, the Diagonale des Fous, Western States and Hardrock are, for many of us, the monuments of ultrarunning. Nobody seemed to have the answer.

So I built Ultra Monuments to find out. It gathers every result of the four races since their first edition, matches the runners across them, and ranks those who have finished all four.

As for me, I’m still one race short: Hardrock. I’ve entered its lottery three times so far, without luck. Until my name comes up, you’ll find me in the “one race away” list.

How it was made

The results come from the DUV Ultra Marathon Statistics database (statistik.d-u-v.org), an extraordinary volunteer effort. I also used this project to discover what artificial intelligence can do: I built the site with the help of Claude, an AI assistant, and checked the numbers along the way.

Errors are possible: a namesake, a missing race, a wrong country. If you spot one, write to contact@ultramonuments.com. Ideas and partnership proposals are welcome at the same address.
