Ski wax Stelvio — Bormio
The Stelvio in Bormio is considered one of the toughest downhills on the calendar: late December, long shaded passages and a mostly icy, aggressive slope. In these conditions, abrasion-resistant race waxes and a preparation tuned to cold, old snow are what count.
Calculated from current conditions — snow temperature, snow type and moisture for 1,225–3,012 m.
To the recommendation for BormioWhy snow temperature decides on the Stelvio
Race waxes are specified for narrow snow-temperature windows — a few degrees decide whether a base runs or goes blunt. Snow temperature deviates systematically from air temperature: at night the slope radiates heat and cools below the air temperature, during the day sun position, exposure and slope angle warm the surface. raceday.ski computes this evolution with a 3-layer energy-balance model and, for Bormio, takes into account the terrain-derived horizon profile (shading) and the altitude of the calculation point — both validated against terrain models in a catalogue-wide quality assurance.
What this means for ski preparation
For race use, raceday.ski recommends a complete system of preparation, base wax, race wax, optional powder top layer and finish — tuned to snow temperature, snow type and moisture class at start time. The start time is an input of its own: a run at 10:00 runs on different snow than a floodlit slalom in the evening.
