Steps
Map each run/trail as a way tagged piste:type (downhill, nordic, skitour, sled, etc.) following OSM's piste namespace conventions
Add piste:difficulty (novice/easy/intermediate/advanced/expert/freeride/extreme) and piste:grooming (classic/mogul/skating/backcountry) per run
Tag piste:name and piste:ref to match on-mountain trail signage/map numbering
Optionally group multi-segment runs into a route=piste relation so a single named run spanning multiple way segments renders as one trail
Export the tagged area via Overpass Turbo (bounding-box query + Export) to GeoJSON for use in a map renderer, validating winding order/CRS before serving it
Known gotchas
piste:status (open/closed) is meant for live data feeds but OSM itself isn't a live system - don't treat OSM as your real-time trail-status source
Difficulty color/symbol conventions differ by region (US green/blue/black vs European blue/red/black/orange) - don't hardcode one country's convention
