Quicksilver 100 km Endurance Run
Calculated from 100 km alone — the organiser has not published an elevation profile. Read 5.0 as a floor, not a verdict.
What the course asks
DUV results for the 2026 edition (100km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
Typical conditions, May
Regional 2001-2020 average for May — NASA POWER, grid elevation 233 m. Not a forecast.
The Aid Station
Course-specific beta from the community
With trail terrain, choose a shoe with moderate cushioning for optimal performance.
For 100km+ efforts, prioritize real food at aid stations to prevent palate fatigue.
