Many On The Genny 45 Mile Trail Ultra
Calculated from 72 km alone — the organiser has not published an elevation profile. Read 3.6 as a floor, not a verdict.
What the course asks
DUV results for the 2026 edition (45mi) — 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 489 m. Not a forecast.
