Headwaters Trail Run 50K
Calculated from 52 km alone — the organiser has not published an elevation profile. Read 2.6 as a floor, not a verdict.
What the course asks
DUV results for the 2026 edition (52km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
Typical conditions, June
Regional 2001-2020 average for June — NASA POWER, grid elevation 1326 m. Not a forecast.
