I eventually got my pictures of the UTMB. I'm not looking quite charming on all of them ... It would be interesting to establish a relationship between the face aspect and the number of kilometers run. I'd expect the experiment to be biaised because everyone tries to smile at the photographer, but well, these results don't show that much biais :)
