Unlike the well-established UTMB, the Petite Trotte à Léon (PTL) race was held for the first time this year.
Even more arduous than the UTMB, the PTL is 220km long and takes runners a total distance of 17km up and down. A maximum of 100 hours is allowed for completion. Participants also do not have as set a route as that for the UTMB. Fifty-nine teams of three each participated in this inaugural race.
The race's control room is pictured above.
