Lost Sierra Endurance Run 50Km
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 2026 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, July
Regional 2001-2020 average for July — NASA POWER, grid elevation 1619 m. Not a forecast.

Course Notes
The racecourse starts in downtown Graeagle, climbs to the crest of the Sierra, skirts the edges of a half-dozen alpine lakes, summits two rugged peaks, and then descends 4,000’ back into Graeagle for the finish.
