Four chilean women, Daniela Navarrete, Veronica Lobos, Valeria Collio and Andrea Lopez did the "O" circuit (without the "W" sections) counter-clockwise in 26 hrs 59 min, starting on March 9th, 2018 at 11:50 pm, and finishing on March 11th, 2018 at 2:49 am. We made it to the 10:00 am cut-off time of Camping Perros with only 3 minutes to spare. Weather conditions were pretty bad, with rain, snow, and very muddy sections. This was unsupported except for a can of Coke and Pringles we bought at Refugio Grey.

And this one shows the complete circuit in one track, but was stopped later:
