Extremo Sul Ultramarathon
Calculated from 226 km alone — the organiser has not published an elevation profile. Read 10.0 as a floor, not a verdict.
What the course asks
DUV results for the 2025 edition (226km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
Typical conditions, November
Regional 2001-2020 average for November — NASA POWER, grid elevation 13 m. Not a forecast.

Course Notes
226km of immense sandy beaches, on a tremendous sandy plain, in an inhospitable and climatically unstable place of enormous contrasts. 54 hours maximum time to cover the route between sand and sea, in a corridor that at times can seem endless.
