Lake Vian 50mi Hilltop Run
Calculated from 80 km alone — the organiser has not published an elevation profile. Read 4.0 as a floor, not a verdict.
What the course asks
DUV results for the 2026 edition (50mi) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
Typical conditions, February
Regional 2001-2020 average for February — NASA POWER, grid elevation 203 m. Not a forecast.
