Rio Del Lago 50 km Race
Calculated from 50 km alone — the organiser has not published an elevation profile. Read 2.5 as a floor, not a verdict.
What the course asks
DUV results for the 2025 edition (50km) — 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 304 m. Not a forecast.
